All questions

Question 1

A 45-year-old male presents with a 9-month history of slowly progressive leg stiffness and walking difficulty. He denies any sensory loss, bladder dysfunction, or cognitive changes. Examination reveals spasticity in the lower extremities, bilateral extensor plantar responses, and hyperreflexia with clonus at the ankles. Upper extremity strength, sensation, and reflexes are within normal limits. There are no fasciculations noted. The patient reports no significant episodes of neurological symptoms in the past.

These findings are MOST consistent with which of the following neurological conditions?

  1. Primary progressive multiple sclerosis (PPMS). (correct answer)
  2. Amyotrophic lateral sclerosis (ALS), lower motor neuron dominant type.
  3. Transverse myelitis with incomplete recovery.
  4. Cervical spondylotic myelopathy.
Explanation: The correct answer is A. This presentation of insidious, slowly progressive spastic paraparesis without relapses or remissions is the classic pattern for primary progressive multiple sclerosis (PPMS). The signs (spasticity, hyperreflexia, Babinski) are purely upper motor neuron (UMN) and are confined to the lower extremities, which is a common onset for PPMS. B is incorrect because ALS involves both UMN and lower motor neuron (LMN) signs. The absence of fasciculations, atrophy, or weakness (LMN signs) makes this diagnosis less likely, especially a lower motor neuron dominant type. C is incorrect because transverse myelitis typically has an acute or subacute onset, often accompanied by a distinct sensory level and bladder dysfunction, which are absent here. D is incorrect because cervical spondylotic myelopathy would typically present with both upper and lower extremity UMN signs, and often neck pain or radicular symptoms in the arms.

Question 2

A 38-year-old male with a history of alcohol abuse is admitted to the hospital with acute pancreatitis. During a physical therapy session for bed mobility, the patient becomes agitated, confused, and experiences a coarse tremor in his hands. His heart rate is 130 bpm, blood pressure is 160/100 mmHg, and he is diaphoretic. His last alcoholic drink was approximately 48 hours ago.

The patient's current signs and symptoms are MOST indicative of which of the following complications?

  1. An adverse reaction to pain medication.
  2. Hypoglycemia secondary to pancreatitis.
  3. A septic encephalopathy from the pancreatitis.
  4. Alcohol withdrawal delirium (delirium tremens). (correct answer)
Explanation: When evaluating a patient with a history of alcohol abuse who's been hospitalized, you need to consider the timeline and constellation of symptoms to identify potential complications. This question tests your ability to recognize alcohol withdrawal syndromes in the acute care setting. The patient's presentation - agitation, confusion, coarse tremor, tachycardia (130 bpm), hypertension (160/100), and diaphoresis occurring 48 hours after his last drink - is classic for alcohol withdrawal delirium (delirium tremens). This severe form of alcohol withdrawal typically occurs 48-96 hours after cessation and represents a medical emergency. The autonomic hyperactivity (elevated heart rate and blood pressure) combined with neurological symptoms (confusion, tremor) in this timeline makes option D correct. Option A is incorrect because adverse reactions to pain medications typically present with sedation, respiratory depression, or allergic responses rather than this hyperadrenergic state. Option B fails because hypoglycemia would more likely cause altered mental status with cool, clammy skin and wouldn't explain the hypertension and tachycardia pattern. Option C represents septic encephalopathy, but the patient lacks fever or other signs of systemic infection, and the 48-hour timeline after alcohol cessation points specifically to withdrawal. Remember that alcohol withdrawal follows a predictable timeline: mild symptoms at 6-12 hours, peak withdrawal at 24-48 hours, and delirium tremens at 48-96 hours. Always consider withdrawal in hospitalized patients with alcohol use disorders, especially when symptoms appear 2-4 days after admission.

Question 3

A 68-year-old female patient is referred to physical therapy for bilateral shoulder pain that began insidiously 6 weeks ago. She reports significant morning stiffness lasting approximately 90 minutes, making it difficult to dress or comb her hair. Passive range of motion is limited in all planes by pain, but no true capsular pattern is identified. Resisted isometric testing of the rotator cuff is 4/5 and painful. Her medical history is significant for giant cell arteritis, which is currently in remission. Her sedimentation rate is elevated at 55 mm/hr.

Based on this clinical presentation, which of the following is the MOST likely underlying condition contributing to the patient's shoulder pain?

  1. Bilateral adhesive capsulitis secondary to prolonged systemic inflammation.
  2. Polymyalgia rheumatica with associated glenohumeral synovitis. (correct answer)
  3. Severe bilateral rotator cuff tendinopathy with impingement syndrome.
  4. Rheumatoid arthritis with early-onset symmetrical shoulder involvement.
Explanation: The correct answer is B. The patient's presentation of age over 50, bilateral, symmetrical shoulder pain, profound morning stiffness (>60 min), and an elevated ESR are classic signs of polymyalgia rheumatica (PMR). The strong association between PMR and giant cell arteritis further supports this diagnosis. The pain and stiffness often affect the shoulder and pelvic girdles. A is incorrect because while adhesive capsulitis can cause stiffness, it typically presents with a clear capsular pattern of restriction (external rotation > abduction > internal rotation), which is absent here. C is incorrect because rotator cuff tendinopathy is less likely to present with such profound bilateral symmetry, prolonged morning stiffness, and a significantly elevated ESR. D is incorrect because while rheumatoid arthritis can cause bilateral shoulder pain, it typically involves smaller joints of the hands and feet first, and a positive rheumatoid factor would be expected.

Question 4

An 82-year-old male with dementia is admitted from a nursing home. The physical therapist is consulted for a mobility assessment. The therapist observes a 5 cm diameter, non-blanchable, deep purple area over the sacrum. The skin is intact, but feels boggy and warmer than the surrounding tissue. The patient's medical record indicates he was found on the floor 12 hours prior to admission after an unwitnessed fall.

Based on the wound characteristics and patient history, what is the MOST accurate classification of this finding?

  1. Stage 1 pressure injury with impending tissue breakdown.
  2. A mature ecchymosis resulting directly from the fall-related trauma.
  3. Suspected deep tissue injury related to prolonged pressure and shear. (correct answer)
  4. Unstageable pressure injury due to obscured tissue depth.
Explanation: The correct answer is C. A suspected deep tissue injury (sDTI) is characterized by a localized area of discolored (purple or maroon) intact skin or a blood-filled blister due to damage of underlying soft tissue from pressure and/or shear. The history of being on the floor for a prolonged period supports this diagnosis. The intact skin with a boggy feel and discoloration is the classic presentation. A is incorrect because a Stage 1 pressure injury is defined as non-blanchable erythema of intact skin, typically red, not deep purple or maroon. B is incorrect because while a bruise can result from a fall, the location over a bony prominence and the specific characteristics (boggy feel, non-blanchable) in a patient with prolonged immobility points more specifically to a pressure-related injury. D is incorrect because an unstageable pressure injury is one where the base of the ulcer is covered by slough or eschar, obscuring the true depth. This patient's skin is intact.

Question 5

A 13-year-old overweight male complains of a 2-month history of a vague, aching pain in his right groin and anterior thigh, which occasionally refers to his knee. The pain is worse with running and climbing stairs. On examination, he walks with a slight limp. Passive hip internal rotation and abduction are significantly limited and reproduce his pain. There is no history of acute trauma. He is afebrile and systemic symptoms are absent.

Given the patient's age, body habitus, and clinical findings, which condition requires the MOST urgent medical evaluation?

  1. Legg-Calvé-Perthes disease.
  2. Slipped capital femoral epiphysis (SCFE). (correct answer)
  3. Femoroacetabular impingement (FAI).
  4. Apophysitis of the anterior inferior iliac spine.
Explanation: The correct answer is B. Slipped capital femoral epiphysis (SCFE) is the most likely diagnosis. It typically occurs in overweight adolescents during their growth spurt. The classic presentation includes a limp and vague groin, thigh, or knee pain. The hallmark physical finding is limited hip internal rotation and abduction. SCFE is considered an orthopedic emergency because a stable slip can become unstable, risking avascular necrosis of the femoral head. A is incorrect because Legg-Calvé-Perthes disease (avascular necrosis of the femoral head) typically affects a younger age group (4-8 years old). C is incorrect because while FAI can cause groin pain and limited rotation, it is less common in this age group and does not carry the same risk of acute instability as SCFE. D is incorrect because apophysitis would present with point tenderness over the AIIS and pain with resisted hip flexion, which are not the primary findings described.

Question 6

A 48-year-old female presents with diffuse proximal muscle weakness, fatigue, and a 20-pound weight gain over the past six months, primarily around her abdomen. She notes easy bruising and has recently developed purple striae on her abdomen. On examination, she has difficulty rising from a chair without using her arms. Blood pressure is elevated at 155/95 mmHg. Lab work shows hyperglycemia.

These clinical features are MOST characteristic of an excess of which hormone?

  1. Thyroxine.
  2. Cortisol. (correct answer)
  3. Growth hormone.
  4. Aldosterone.
Explanation: The correct answer is B. This is a classic presentation of Cushing's syndrome, which is caused by prolonged exposure to excess cortisol. Key features include central obesity, proximal muscle weakness (steroid myopathy), purple striae, easy bruising, hypertension, and hyperglycemia. The combination of all these signs is highly specific for hypercortisolism. A is incorrect. Excess thyroxine (hyperthyroidism) causes weight loss, heat intolerance, tachycardia, and sometimes proximal muscle weakness, but not the central obesity or purple striae. C is incorrect. Excess growth hormone (acromegaly) causes enlargement of hands, feet, and facial features, but not the characteristic body fat distribution or skin changes of Cushing's. D is incorrect. Excess aldosterone (hyperaldosteronism) primarily causes hypertension and hypokalemia, but not the other systemic features described.

Question 7

A 60-year-old male presents with gait disturbance and neck pain. Examination reveals a spastic gait, generalized hyperreflexia in both upper and lower extremities, positive Hoffman's and Babinski signs bilaterally, and weakness of the intrinsic hand muscles. He also has widespread fasciculations in his biceps, triceps, and quadriceps. Sensation to light touch and pinprick is intact throughout. He denies any bowel or bladder changes.

Which diagnosis BEST accounts for the combination of upper and lower motor neuron signs in both upper and lower extremities, along with the preservation of sensation?

  1. Amyotrophic lateral sclerosis (ALS). (correct answer)
  2. Cervical spondylotic myelopathy.
  3. Multiple sclerosis, primary progressive type.
  4. Syringomyelia of the cervical spine.
Explanation: When you encounter a patient with both upper and lower motor neuron signs affecting multiple extremities while preserving sensation, you're dealing with a motor neuron disease pattern. The key is recognizing how different conditions affect the motor versus sensory systems. The combination described here—spastic gait, hyperreflexia, positive Hoffman's and Babinski signs (upper motor neuron signs) alongside fasciculations and intrinsic hand muscle weakness (lower motor neuron signs)—with completely intact sensation points directly to amyotrophic lateral sclerosis (ALS). ALS selectively destroys motor neurons in both the brain and spinal cord while sparing sensory pathways, which explains why this patient has no sensory deficits or bowel/bladder dysfunction. Option B, cervical spondylotic myelopathy, would primarily cause upper motor neuron signs due to spinal cord compression, but wouldn't typically produce the widespread fasciculations or pure lower motor neuron findings seen here. Option C, primary progressive multiple sclerosis, could cause upper motor neuron signs but rarely produces lower motor neuron findings like fasciculations, and often involves sensory symptoms. Option D, syringomyelia, characteristically causes a "cape-like" sensory loss pattern affecting pain and temperature sensation while sparing light touch—the opposite of what's described. For the NPTE, remember that ALS is the classic "pure motor" disease. When you see mixed upper and lower motor neuron signs with preserved sensation throughout all extremities, think ALS first. The presence of fasciculations alongside spasticity and hyperreflexia is particularly diagnostic.

Question 8

A 28-year-old female reports a 6-month history of widespread body pain, profound fatigue, and unrefreshing sleep. She describes the pain as a constant, dull ache that is present in her neck, back, shoulders, and hips. She also notes frequent headaches and difficulty concentrating ('fibro fog'). A physical examination is largely unremarkable except for tenderness to palpation at multiple specific points. She has a faint, reddish rash across her cheeks and the bridge of her nose.

The presence of the facial rash in addition to her other symptoms should prompt the therapist to consider which of the following as a potential underlying diagnosis?

  1. Chronic fatigue syndrome.
  2. Fibromyalgia as a primary diagnosis.
  3. Polymyalgia rheumatica.
  4. Systemic lupus erythematosus (SLE). (correct answer)
Explanation: When you encounter a patient presenting with multiple systemic symptoms, it's crucial to recognize red flags that might indicate a serious underlying condition rather than accepting the most obvious diagnosis at face value. While this patient's symptoms of widespread pain, fatigue, unrefreshing sleep, and tender points strongly suggest fibromyalgia, the presence of a facial rash is a critical differentiating feature. The "faint, reddish rash across her cheeks and the bridge of her nose" describes a classic malar (butterfly) rash, which is a hallmark sign of systemic lupus erythematosus (SLE). This autoimmune condition can present with fibromyalgia-like symptoms but requires immediate medical attention and different treatment approaches. The correct answer is D. Looking at the distractors: A) Chronic fatigue syndrome doesn't typically involve facial rashes or the specific tender points described. B) While fibromyalgia explains most symptoms, you cannot ignore the facial rash, which isn't characteristic of primary fibromyalgia. C) Polymyalgia rheumatica primarily affects older adults (typically over 50) and involves different pain patterns, particularly in the shoulders and hips, without facial manifestations. Remember that fibromyalgia can be secondary to other conditions, including SLE. When you see classic fibromyalgia symptoms plus any unusual features—especially skin manifestations like rashes—always consider underlying autoimmune or systemic conditions. This is a common NPTE pattern: testing your ability to recognize when additional symptoms warrant further investigation rather than accepting the most apparent diagnosis.

Question 9

A 67-year-old male with peripheral arterial disease complains of bilateral calf and thigh pain after walking 200 feet. He states the pain is reliably relieved by standing still for 2-3 minutes. He also mentions that when he walks through the grocery store leaning on the shopping cart, he can walk for much longer distances without pain. A bicycle test performed in the clinic shows that he can pedal for 15 minutes against resistance in a slumped, forward-flexed posture without leg pain.

What is the MOST likely interpretation of these findings?

  1. The patient most likely has neurogenic claudication secondary to lumbar spinal stenosis. (correct answer)
  2. The patient's symptoms are consistent with purely vascular claudication.
  3. The patient has a combination of both vascular and neurogenic claudication.
  4. The shopping cart sign is a false positive and the symptoms are from severe hip osteoarthritis.
Explanation: When evaluating claudication symptoms, you need to distinguish between vascular (blood flow) and neurogenic (nerve compression) causes, as they require different treatments and have distinct clinical presentations. The key diagnostic clue here is the shopping cart sign - the patient can walk much longer distances when leaning forward on a cart. This forward-flexed posture opens up the spinal canal and relieves compression on neural structures, which is pathognomonic for neurogenic claudication from lumbar spinal stenosis. The bicycle test further confirms this: cycling naturally places the spine in flexion, allowing 15 minutes of activity without symptoms. In pure vascular claudication, posture wouldn't matter - any sustained muscle activity would trigger symptoms regardless of spinal position. Answer A is correct because the shopping cart sign and bicycle test are classic findings for neurogenic claudication. The forward flexion relieves spinal stenosis symptoms by increasing the diameter of the spinal canal. Answer B is wrong because purely vascular claudication wouldn't improve with postural changes. The symptoms would occur consistently with any walking activity regardless of spine position. Answer C is incorrect because there's no evidence supporting a vascular component. The patient's ability to exercise without symptoms in forward flexion strongly suggests the problem is purely neurogenic, not mixed. Answer D misinterprets the shopping cart sign as a false positive. This sign is actually highly specific for lumbar spinal stenosis, and hip osteoarthritis wouldn't explain the postural relief pattern or the bicycle test results. Study tip: Remember the shopping cart sign - it's a high-yield finding that reliably distinguishes neurogenic from vascular claudication on the NPTE.

Question 10

A 35-year-old female presents with pain at the radial side of her wrist, which is aggravated by lifting her newborn child. Finkelstein's test is positive. However, the therapist also notes sausage-like swelling (dactylitis) of the second digit, and the patient reports nail pitting on several fingernails. She also complains of morning stiffness in her hands and feet lasting about 45 minutes.

This combination of findings suggests that the patient's wrist pain is MOST likely a component of which systemic condition?

  1. De Quervain's tenosynovitis.
  2. Rheumatoid arthritis.
  3. Systemic lupus erythematosus.
  4. Psoriatic arthritis. (correct answer)
Explanation: When you encounter a question combining local musculoskeletal symptoms with systemic signs, always look beyond the obvious diagnosis to identify underlying conditions that could explain the full clinical picture. While this patient has a positive Finkelstein's test suggesting De Quervain's tenosynovitis, the additional findings point to psoriatic arthritis. The key diagnostic clues are the combination of dactylitis (sausage-like digit swelling), nail pitting, and prolonged morning stiffness. Psoriatic arthritis commonly affects the hands and wrists, and can present with tenosynovitis that mimics De Quervain's. The timing with lifting her newborn likely represents symptom aggravation rather than causation. Option A (De Quervain's tenosynovitis) only explains the wrist pain and positive Finkelstein's test but doesn't account for the dactylitis, nail changes, or systemic morning stiffness. Option B (rheumatoid arthritis) could explain morning stiffness and joint involvement, but dactylitis is rare in RA, and nail pitting is not a feature. Option C (systemic lupus erythematosus) typically presents with different patterns of joint involvement and doesn't commonly cause dactylitis or nail pitting. The correct answer is D because psoriatic arthritis uniquely combines all these features: tenosynovitis (explaining the positive Finkelstein's test), dactylitis, nail pitting, and prolonged morning stiffness. Study tip: Remember that dactylitis and nail pitting are pathognomonic signs of psoriatic arthritis. When you see these findings with any musculoskeletal complaint, consider psoriatic arthritis as the underlying systemic cause rather than treating symptoms in isolation.

Question 11

A 52-year-old female presents three days post-total knee arthroplasty with a sudden onset of shortness of breath, pleuritic chest pain, and anxiety. Her vital signs are: heart rate 115 bpm, respiratory rate 24 breaths/min, blood pressure 130/80 mmHg, and oxygen saturation 91% on room air. Auscultation of the lungs reveals clear breath sounds bilaterally. She has mild calf tenderness but a negative Homan's sign.

The patient's signs and symptoms are MOST suggestive of which postoperative complication?

  1. Atelectasis.
  2. Pulmonary embolism. (correct answer)
  3. Postoperative pneumonia.
  4. Anxiety-induced hyperventilation.
Explanation: The correct answer is B. The constellation of acute dyspnea, pleuritic chest pain, tachycardia, tachypnea, and hypoxemia in a patient who recently underwent a major lower extremity surgery is highly suspicious for a pulmonary embolism (PE). The negative Homan's sign is not reliable for ruling out DVT, which is the most common source of a PE. A is incorrect because while atelectasis is common post-op, it typically does not cause pleuritic chest pain or such a significant degree of tachycardia and hypoxemia. Breath sounds might be diminished, not clear. C is incorrect because pneumonia usually presents with fever, productive cough, and crackles or ronchi on auscultation, none of which are present. D is incorrect because while the patient is anxious, the hypoxemia (SpO2 91%) is an objective sign of a physiological problem, not just anxiety. Hyperventilation from anxiety would more likely lead to respiratory alkalosis without hypoxemia.

Question 12

A 62-year-old patient with poorly controlled type 2 diabetes presents with a full-thickness ulcer on the plantar surface of the first metatarsal head. The wound base is pale with minimal granulation tissue. The periwound skin is thin, shiny, and hairless, with a cool temperature upon palpation. The dorsalis pedis pulse is non-palpable, and the ankle-brachial index (ABI) is 0.65.

These findings are MOST indicative of which type of ulcer?

  1. A purely neuropathic ulcer with secondary infection.
  2. A venous stasis ulcer with atypical location.
  3. A pressure injury from improperly fitting footwear.
  4. A neuroischemic ulcer with significant arterial insufficiency. (correct answer)
Explanation: When evaluating lower extremity ulcers in patients with diabetes, you need to distinguish between three main types: neuropathic, ischemic, and neuroischemic. The key is systematically analyzing the clinical presentation, vascular status, and wound characteristics. This patient presents classic signs of arterial insufficiency combined with diabetic neuropathy. The pale wound base with minimal granulation tissue indicates poor blood supply—healthy granulation tissue appears red and beefy due to adequate perfusion. The periwound skin changes (thin, shiny, hairless, and cool) are hallmark signs of chronic arterial insufficiency. Most importantly, the non-palpable dorsalis pedis pulse and ABI of 0.65 confirm significant vascular compromise (normal ABI is 0.9-1.3; values below 0.8 indicate arterial disease). Option A is incorrect because purely neuropathic ulcers typically have good granulation tissue and normal perfusion signs—this patient clearly has vascular compromise. Option B is wrong because venous stasis ulcers occur around the medial malleolus, not on pressure points like the first metatarsal head, and they present with different skin changes (hemosiderin staining, edema). Option C misses the underlying pathophysiology—while ill-fitting shoes may contribute, the vascular findings indicate this is primarily a circulation problem, not just mechanical pressure. The correct answer is D because this represents a neuroischemic ulcer: diabetes causes the neuropathy (allowing injury at the pressure point), while arterial disease impairs healing and creates the pale, poorly perfused wound appearance. Remember: Always assess vascular status in diabetic foot ulcers—check pulses, skin changes, and ABI to differentiate neuropathic from neuroischemic presentations.

Question 13

A patient with a 15-year history of Crohn's disease is referred for physical therapy due to insidious onset of low back and right buttock pain over the past 3 months. The pain is worst in the morning with stiffness lasting over an hour and improves with activity. He reports no specific injury. The pain occasionally wakes him during the second half of the night. Examination reveals tenderness over the right sacroiliac joint and a positive thigh thrust test. Lumbar range of motion is full but painful at end-range extension.

The patient's clinical presentation is MOST indicative of which of the following conditions?

  1. Lumbar facet joint arthropathy with referred pain to the buttock.
  2. Piriformis syndrome causing compression of the sciatic nerve.
  3. Sacroiliitis associated with inflammatory bowel disease. (correct answer)
  4. Lumbar spinal stenosis with neurogenic claudication.
Explanation: The correct answer is C. The patient's history of Crohn's disease (an inflammatory bowel disease) combined with the classic signs of inflammatory back pain (insidious onset, morning stiffness > 60 min, improvement with activity, nocturnal pain) and positive sacroiliac joint provocation testing strongly suggests sacroiliitis. This is a common extra-intestinal manifestation of IBD. A is incorrect because facet arthropathy typically presents as mechanical pain, which worsens with activity (especially extension) and improves with rest, the opposite of this patient's pattern. B is incorrect because piriformis syndrome would not typically cause prolonged morning stiffness or night pain that improves with activity. D is incorrect because lumbar spinal stenosis usually affects an older population and causes neurogenic claudication (pain with walking that is relieved by sitting or flexing forward), which is not described here.

Question 14

A 55-year-old female with a history of type 2 diabetes and obesity is being treated for a right frozen shoulder. During the examination of her lower extremities, the therapist notes a rocker-bottom deformity of her left foot, which the patient states has developed slowly over the past year without any significant pain or trauma. The foot is warm and erythematous compared to the contralateral side. Dorsalis pedis pulse is 2+/4 bilaterally.

The combination of the patient's frozen shoulder and the left foot presentation is MOST likely indicative of which underlying systemic process?

  1. Poorly controlled diabetes mellitus leading to both connective tissue and neuropathic changes. (correct answer)
  2. Rheumatoid arthritis affecting both appendicular and axial joints.
  3. Complex regional pain syndrome affecting both upper and lower extremities.
  4. Peripheral vascular disease causing ischemic changes in multiple extremities.
Explanation: The correct answer is A. This is a multi-step reasoning question. The frozen shoulder (adhesive capsulitis) has a high incidence in patients with diabetes, likely due to glycosylation of collagen. The painless, progressive rocker-bottom deformity with erythema and warmth in a diabetic patient is the classic presentation of Charcot neuroarthropathy. Both conditions are well-known complications of poorly controlled diabetes. B is incorrect because rheumatoid arthritis typically presents with painful, inflammatory synovitis, which does not match the painless deformity of the foot. C is incorrect because CRPS is characterized by severe pain that is out of proportion to any injury, which is contrary to the painless nature of the patient's foot condition. D is incorrect because the presence of strong (2+/4) dorsalis pedis pulses makes significant peripheral vascular disease less likely as the primary cause of the foot deformity.

Question 15

A 66-year-old male with a significant smoking history and a recent diagnosis of severe COPD is hospitalized for an acute exacerbation. He is connected to a cardiac monitor, which shows a heart rate of 120 bpm with a continuously varying P-wave morphology and irregular R-R intervals. The monitor labels the rhythm as multifocal atrial tachycardia (MAT). The patient is scheduled for physical therapy for airway clearance techniques.

What is the MOST significant implication of this cardiac rhythm for the physical therapy session?

  1. The rhythm is a contraindication to airway clearance techniques due to risk of cardiac arrest.
  2. The patient's hemodynamic instability may limit his tolerance for positional changes and exertion. (correct answer)
  3. The rhythm is a benign finding commonly associated with bronchodilator use in COPD patients.
  4. The patient should be placed in a Trendelenburg position to improve cardiac preload and stabilize the rhythm.
Explanation: The correct answer is B. Multifocal atrial tachycardia (MAT) is an arrhythmia strongly associated with severe pulmonary disease, such as a COPD exacerbation. While not immediately life-threatening, it indicates significant cardiac stress secondary to hypoxia and metabolic derangement. The rapid, irregular ventricular response can impair diastolic filling time, potentially leading to hemodynamic instability (e.g., hypotension, worsening ischemia). This instability will likely limit the patient's tolerance for activity, including aggressive airway clearance and postural drainage. A is too strong; MAT is not an absolute contraindication, but it requires caution and close monitoring. C is an oversimplification; while associated with COPD, it is not benign and signifies severe underlying physiological stress. D is contraindicated; the Trendelenburg position would increase work of breathing in a patient with severe COPD and would not be an appropriate intervention for MAT.

Question 16

A 65-year-old male with a history of metastatic prostate cancer to the bone is receiving outpatient physical therapy for generalized weakness. He reports a new onset of severe, deep, boring mid-thoracic back pain that has been present for one week. The pain is constant, worse at night, and not relieved by changes in position. He denies any recent trauma. Neurological screening of the lower extremities is currently unremarkable.

Given the patient's history and new symptoms, which action is MOST appropriate for the physical therapist to take?

  1. Initiate gentle spinal mobilization techniques to address mechanical pain.
  2. Instruct the patient in positioning strategies for pain relief and continue with the established plan of care.
  3. Immediately contact the referring oncologist to report suspected spinal cord compression. (correct answer)
  4. Place the current plan of care on hold and re-evaluate the patient in one week to assess symptom progression.
Explanation: The correct answer is C. The patient's symptoms are red flags for spinal metastasis leading to potential spinal cord compression, which is an oncologic emergency. The key features are the history of cancer known to metastasize to bone, new onset of severe back pain, and the non-mechanical nature of the pain (constant, worse at night, not relieved by position changes). Even without current neurological deficits, this presentation warrants immediate communication with the oncologist for urgent medical evaluation. A is incorrect and potentially harmful, as mobilization is contraindicated with suspected spinal metastasis. B and D are incorrect because they delay necessary medical intervention for a time-sensitive and potentially catastrophic condition.

Question 17

A 72-year-old female with a history of hypertension and diastolic dysfunction undergoes a submaximal exercise test. Her resting heart rate is 80 bpm and blood pressure is 135/85 mmHg. After 6 minutes on the treadmill, she reports significant dyspnea and fatigue, forcing her to stop. Her peak heart rate is 130 bpm, and blood pressure is 190/95 mmHg. Oxygen saturation remains 96% on room air. The primary reason for test termination is exertional dyspnea, disproportionate to the workload achieved.

Which pathophysiological mechanism BEST explains the patient's primary limitation during the exercise test?

  1. Chronotropic incompetence preventing an adequate heart rate response to exercise.
  2. Impaired ventricular systolic function leading to a low cardiac output.
  3. Abnormally high left ventricular filling pressures due to poor ventricular relaxation. (correct answer)
  4. Peripheral oxygen extraction limitations from skeletal muscle deconditioning.
Explanation: The correct answer is C. The patient has a history of diastolic dysfunction, which is the hallmark of heart failure with preserved ejection fraction (HFpEF). In HFpEF, the ventricle is stiff and does not relax properly, leading to elevated left ventricular end-diastolic pressures (LVEDP), especially with exertion. This increased pressure backs up into the pulmonary circulation, causing pulmonary congestion and the sensation of severe dyspnea. A is incorrect because her heart rate increased by 50 bpm, a reasonable response for a submaximal test, not indicating chronotropic incompetence. B is incorrect because impaired systolic function is characteristic of HFrEF, not HFpEF (diastolic dysfunction). D is incorrect because while deconditioning may be a factor, the severe dyspnea points to a central cardiorespiratory limitation, specifically the high filling pressures, rather than a primary peripheral limitation.

Question 18

A 42-year-old male cyclist presents with perineal and pelvic pain, urinary urgency, and frequency. The pain is vaguely located and he has difficulty sitting for long periods. A urologist has ruled out a bacterial infection. Physical examination reveals significant tenderness to palpation of the obturator internus and levator ani muscles. There is no sacroiliac joint or lumbar spine tenderness. All neurological testing is normal.

This patient's cluster of symptoms is MOST consistent with which of the following diagnoses?

  1. Pudendal nerve entrapment.
  2. Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), non-bacterial. (correct answer)
  3. Sacroiliac joint dysfunction with anterior referred pain.
  4. Interstitial cystitis/painful bladder syndrome.
Explanation: The correct answer is B. The combination of pelvic pain, urinary symptoms (urgency, frequency), and myofascial tenderness in the pelvic floor muscles, in the absence of a bacterial infection, is the classic presentation of non-bacterial Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS), specifically Type IIIb (non-inflammatory). The tenderness of obturator internus and levator ani is a key finding pointing to musculoskeletal involvement. A is incorrect because while pudendal nerve entrapment can cause perineal pain, it typically involves more distinct neuropathic symptoms (burning, numbness) in the nerve's distribution and is less commonly associated with urinary frequency and urgency. C is incorrect because the examination specifically ruled out SI joint tenderness. D is incorrect because interstitial cystitis is primarily characterized by bladder pain that is relieved by voiding, and while it shares urinary symptoms, the prominent pelvic floor muscle tenderness points more toward CP/CPPS.

Question 19

A 22-year-old male presents with a progressive foot drop that developed over the past few months. He reports tripping frequently. Examination reveals weakness of ankle dorsiflexion and eversion (3/5), and weakness of the extensor hallucis longus (2/5). Sensation is diminished over the dorsum of the foot and the lateral calf. Ankle inversion and plantarflexion are strong (5/5). He has high arches (pes cavus) and mild hammertoe deformities bilaterally. His father had similar foot problems starting in his twenties.

Given the bilateral foot deformities and family history, what is the MOST likely underlying diagnosis?

  1. L5 radiculopathy from a herniated nucleus pulposus.
  2. Traumatic common fibular (peroneal) nerve palsy.
  3. Charcot-Marie-Tooth disease. (correct answer)
  4. Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy (CIDP) variant.
Explanation: The correct answer is C. This presentation is highly suggestive of Charcot-Marie-Tooth (CMT) disease, a hereditary motor and sensory neuropathy. Key features are the insidious onset of distal weakness (foot drop), sensory loss, the characteristic pes cavus foot structure, and a positive family history. The weakness pattern perfectly matches the muscles innervated by the fibular nerve, which is commonly affected in CMT. A is incorrect because L5 radiculopathy is typically unilateral, often associated with back pain, and would also involve weakness in tibialis posterior (inversion), which is strong here. B is incorrect because a traumatic palsy would have an acute onset related to an injury and is typically unilateral. D is incorrect because CIDP, while causing progressive weakness, is an autoimmune condition and does not cause the congenital bony deformities (pes cavus, hammertoes) seen in this patient.
