All questions

Question 1

A patient with LBP has morning stiffness and saddle numbness. Which finding alone warrants urgent referral?

  1. Saddle numbness (correct answer)
  2. Morning stiffness
  3. Pain with bending
  4. Mild leg ache
Explanation: Saddle numbness is a red flag for cauda equina syndrome, which can cause permanent bowel, bladder, and lower-extremity damage if not treated emergently. It warrants urgent referral even as the only symptom. Morning stiffness is the most tempting wrong choice, but it points to inflammatory back pain, not an emergency; it can be evaluated non-urgently.

Question 2

A patient has acute shoulder pain, fever, and painful passive motion. What is the best action?

  1. Apply ice to the shoulder
  2. Start gentle pendulum motions
  3. Refer for septic joint workup (correct answer)
  4. Schedule recheck tomorrow
Explanation: Fever with acute shoulder pain and pain even with passive motion are red flags for septic arthritis, which can destroy the joint rapidly. The best action is urgent referral for joint aspiration and workup. Applying ice may ease symptoms but delays diagnosis and treatment, so it is the tempting but unsafe choice.

Question 3

After neck manipulation, which finding with vertigo warrants emergency referral over canalith repositioning?

  1. Nystagmus with fatigue
  2. New onset slurred speech (correct answer)
  3. Positive Dix-Hallpike
  4. Neck pain with rotation
Explanation: Slurred speech after neck manipulation suggests possible vertebral artery dissection or stroke, which is a true emergency and requires immediate referral. Canalith repositioning is only for benign positional vertigo, not for brainstem or vascular symptoms. The tempting wrong answer is nystagmus with fatigue, because that pattern does suggest BPPV, but it is not an emergency red flag.

Question 4

A patient on long-term prednisone develops acute severe back pain after bending. What is the best action?

  1. Continue usual exercises
  2. Begin hamstring stretches
  3. Apply moist heat and rest
  4. Refer for spinal imaging (correct answer)
Explanation: Long-term prednisone weakens bones, so acute severe back pain after bending suggests a vertebral compression fracture. You need spinal imaging to confirm or rule out fracture before any exercise or manual therapy. The most tempting wrong choice is applying moist heat and rest, but that masks symptoms and delays fracture management.

Question 5

For a patient 2 weeks after knee arthroplasty with calf swelling, which finding most clearly warrants medical referral?

  1. Unilateral calf warmth (correct answer)
  2. Generalized leg fatigue
  3. Pain when walking starts
  4. Stiffness after rest
Explanation: Two weeks after knee arthroplasty, new unilateral calf swelling with warmth suggests deep vein thrombosis, which needs immediate medical evaluation. Generalized fatigue, start-of-walk pain, or rest stiffness are common post-op symptoms and don't signal an urgent complication. The most tempting distractor is pain when walking starts because it seems localized, but this is typical incisional or muscle pain, not a red flag.

Question 6

Which finding suggests a need for immediate referral in a patient with low back pain and new urinary retention and saddle numbness?

  1. Pain increases with prolonged sitting and improves with walking
  2. Positive slump test reproducing posterior thigh symptoms
  3. New urinary retention with saddle anesthesia symptoms (correct answer)
  4. Lumbar flexion limited to fingertips reaching mid-shin
Explanation: This question tests NPTE-level skills in recognizing examination findings indicating the need for referral or further medical evaluation. Referral indicators are critical in physical therapy to ensure patient safety and appropriate management. Recognizing red flags such as neurological signs, cardiovascular abnormalities, or unexplained systemic symptoms can guide necessary referrals. In this scenario, the patient's new urinary retention and saddle anesthesia with low back pain suggest a referral for possible cauda equina syndrome is warranted. Choice C is correct because it aligns with clinical guidelines for referring patients exhibiting signs of acute neurological compression. Choice A is incorrect because it misinterprets the symptoms as mechanical back pain, ignoring the potential for serious emergent conditions. To help students: Encourage recognition of symptom patterns that deviate from expected recovery or health status. Practice case studies focusing on identifying red flags and appropriate referral decisions. Watch for: overlooking systemic symptoms, assuming benign causes without thorough evaluation.

Question 7

Based on new irregularly irregular pulse, dizziness, and BP 78/46 mmHg during warm-up, what should the PT do next?

  1. Stop activity and activate emergency medical services (correct answer)
  2. Have patient drink water and resume at lower intensity
  3. Continue monitoring and complete the planned treatment session
  4. Treat as orthostatic intolerance with ankle pumps only
Explanation: This question tests NPTE-level skills in recognizing examination findings indicating the need for referral or further medical evaluation. Referral indicators are critical in physical therapy to ensure patient safety and appropriate management. Recognizing red flags such as neurological signs, cardiovascular abnormalities, or unexplained systemic symptoms can guide necessary referrals. In this scenario, the patient's new irregularly irregular pulse, dizziness, and low blood pressure suggest a referral to emergency services for possible arrhythmia or shock is warranted. Choice A is correct because it aligns with clinical guidelines for referring patients exhibiting signs of acute cardiovascular instability. Choice B is incorrect because it misinterprets the symptoms as dehydration, ignoring the potential for serious cardiac conditions. To help students: Encourage recognition of symptom patterns that deviate from expected recovery or health status. Practice case studies focusing on identifying red flags and appropriate referral decisions. Watch for: overlooking systemic symptoms, assuming benign causes without thorough evaluation.

Question 8

A 55-year-old male presents with an insidious onset of mid-thoracic back pain over the last month. He describes the pain as a deep, boring ache that is worse at night and frequently wakes him from sleep. The pain is not significantly altered by changes in position or by rest. His past medical history is notable for prostate cancer, which was treated with a prostatectomy 5 years ago and has been in remission. Examination reveals tenderness to palpation over the T7 spinous process, but active and passive thoracic range of motion do not reproduce his primary pain complaint.

Which component of the patient's presentation is the MOST compelling reason for an immediate referral to a physician?

  1. The history of prostate cancer in remission for 5 years.
  2. Tenderness to palpation over the T7 spinous process.
  3. The insidious onset of pain without a clear mechanism of injury.
  4. Pain that is constant, intense, and unrelieved by rest or position changes. (correct answer)
Explanation: The correct answer is D. The pain pattern—constant, intense, worse at night, and not relieved by rest or positional changes—is a classic red flag for a non-mechanical cause of back pain, such as infection, inflammation, or malignancy. Given the patient's history of prostate cancer, spinal metastasis must be considered. While the history of cancer (A) is a significant risk factor, the current clinical pain pattern is the most active and urgent finding. Spinous process tenderness (B) is a non-specific finding common in both mechanical and systemic conditions. Insidious onset (C) can occur with mechanical pain and is less specific than the pain's behavior.

Question 9

A 62-year-old female presents with a 2-day history of left shoulder pain that began without any trauma. She describes the pain as a deep ache located primarily in the axilla and anterior chest wall, with radiation to the medial aspect of her left arm. She reports that the pain is most severe when she walks up the single flight of stairs to her apartment, at which time she also feels short of breath and sweaty. The physical therapist's examination reveals full and painless active and passive range of motion of the left shoulder in all planes.

Based on these findings, what is the MOST appropriate immediate action for the physical therapist?

  1. Perform special tests for thoracic outlet syndrome, such as Adson's test.
  2. Instruct the patient in pendulum exercises and apply ice to the shoulder.
  3. Activate emergency medical services or refer for immediate medical evaluation. (correct answer)
  4. Advise the patient to follow up with her primary care physician within the week.
Explanation: The correct answer is C. This patient's presentation is highly suspicious for an acute cardiac event (myocardial infarction). Key red flags include pain exacerbated by exertion (climbing stairs), associated systemic symptoms (shortness of breath, diaphoresis), a non-mechanical pain pattern (full, painless shoulder ROM), and a typical referral pattern for cardiac ischemia (left chest, axilla, medial arm). This constitutes a medical emergency. Performing TOS tests (A) or treating it as a musculoskeletal issue (B) would be inappropriate and dangerous. A routine follow-up (D) is not sufficiently urgent.

Question 10

A 45-year-old female is evaluated in physical therapy 3 days after feeling a 'tweak' in her right calf while playing tennis. She presents with localized tenderness, mild swelling, and warmth in the posterior calf. She reports a persistent feeling of 'tightness' and pain with ambulation. The therapist calculates a Wells' score for DVT of 3 based on calf swelling, localized tenderness along the deep venous system, and a recent history of immobilization due to a long flight last week. A Homan's sign is also positive.

The physical therapist's examination findings are most consistent with the need to take which of the following actions?

  1. Initiate treatment for a grade 1 gastrocnemius strain with ice, compression, and elevation.
  2. Refer the patient for an immediate medical assessment to rule out deep vein thrombosis. (correct answer)
  3. Perform gentle passive stretching of the calf musculature to alleviate the tightness.
  4. Apply therapeutic ultrasound over the tender area to promote tissue healing and reduce pain.
Explanation: The correct answer is B. A Wells' score of 3 or greater indicates a high probability of deep vein thrombosis (DVT). The cluster of findings (unilateral swelling, tenderness, recent immobilization) strongly suggests a DVT over a simple muscle strain. A DVT is a medical emergency requiring immediate evaluation and anticoagulation to prevent a pulmonary embolism. Treating it as a muscle strain (A), stretching the calf (C), or applying ultrasound (D) are all contraindicated as they could potentially dislodge a thrombus.

Question 11

A 38-year-old male presents via direct access with a severe headache that began suddenly during a heavy deadlift two hours ago. He describes it as the 'worst headache of my life' and a 'thunderclap' onset. He also complains of neck stiffness, sensitivity to light, and nausea. He has no prior history of migraines. The physical therapist's examination reveals nuchal rigidity and a positive Brudzinski's sign.

These examination findings are MOST indicative of the need for which action?

  1. Instruction in relaxation techniques and trigger point release for a tension-type headache.
  2. Immediate referral to an emergency department for suspected subarachnoid hemorrhage. (correct answer)
  3. Treatment for cervicogenic headache with manual therapy to the upper cervical spine.
  4. Referral to a neurologist for an outpatient evaluation of new-onset migraines.
Explanation: The correct answer is B. The 'thunderclap' headache onset, especially during exertion (valsalva), is a major red flag for a subarachnoid hemorrhage. The associated signs of meningeal irritation (neck stiffness/nuchal rigidity, photophobia, positive Brudzinski's sign) further support this suspicion. This is a life-threatening medical emergency that requires immediate evaluation in an emergency department. Treating it as a cervicogenic (C) or tension-type (A) headache would be catastrophic. A non-urgent neurology referral (D) is an inappropriate delay of care.

Question 12

A patient is being treated for neck pain following a motor vehicle accident 2 weeks prior. During the application of a grade III central posterior-to-anterior mobilization to the C2 vertebra, the patient suddenly reports severe dizziness, nausea, and that he is 'seeing double.' The therapist immediately ceases the technique and, upon observing the patient's eyes, notes a persistent nystagmus with a vertical, down-beating pattern.

The patient's acute signs and symptoms are MOST indicative of which of the following conditions?

  1. Benign paroxysmal positional vertigo (BPPV).
  2. A vasovagal response to the manual technique.
  3. Vertebrobasilar insufficiency. (correct answer)
  4. Exacerbation of cervicogenic dizziness.
Explanation: The correct answer is C. The sudden onset of the '5 D's' (dizziness, diplopia) and '3 N's' (nausea, nystagmus) during a neck movement is highly suggestive of vertebrobasilar insufficiency (VBI). Persistent vertical nystagmus is a cardinal sign of a central nervous system lesion, unlike the torsional nystagmus of BPPV (A), which is also typically latent and fatiguing. Cervicogenic dizziness (D) is a diagnosis of exclusion and does not typically present with diplopia or central nystagmus patterns. A vasovagal response (B) would involve pre-syncope but not these specific neurological signs.

Question 13

A 70-year-old male with a history of hypertension presents with low back and left flank pain of 4 weeks' duration. He describes the pain as a constant, deep, 'boring' sensation that is not significantly affected by movement or position. During the examination, the physical therapist is able to palpate a prominent, pulsating mass in the central abdomen, superior to the umbilicus.

Which action is MOST appropriate for the physical therapist to take?

  1. Perform a screening examination of the lumbar spine and hip.
  2. Apply a hot pack to the lumbar spine to alleviate muscle spasm.
  3. Refer the patient for immediate medical evaluation for a suspected abdominal aortic aneurysm. (correct answer)
  4. Instruct the patient in gentle core strengthening and stretching exercises.
Explanation: The correct answer is C. The combination of non-mechanical back/flank pain and a palpable, pulsating abdominal mass is the cardinal sign of an abdominal aortic aneurysm (AAA). This is a life-threatening condition that requires immediate medical attention. Performing a standard musculoskeletal examination (A) or initiating any form of treatment (B, D) would dangerously delay necessary medical care and could potentially lead to rupture.

Question 14

While treating a 55-year-old patient with fair skin and a history of working outdoors for his right shoulder adhesive capsulitis, the physical therapist notices a lesion on the posterior aspect of the shoulder. The lesion is dark, has an irregular border, appears to have multiple shades of brown and black, and measures approximately 7 mm in diameter. The patient reports he was not aware of the lesion.

What is the physical therapist's MOST appropriate course of action?

  1. Document the lesion's characteristics and monitor it for changes at subsequent visits.
  2. Reassure the patient that such lesions are common and likely benign.
  3. Advise the patient to see a physician as soon as possible for evaluation of the lesion. (correct answer)
  4. Avoid manual therapy techniques near the lesion to prevent irritation.
Explanation: The correct answer is C. The lesion displays several characteristics consistent with the 'ABCDE' rule for melanoma: Asymmetry, irregular Border, multiple Colors, and Diameter greater than 6 mm. This is highly suspicious for a malignant melanoma, a serious form of skin cancer. The therapist's professional responsibility is to recognize these signs and refer the patient for prompt medical evaluation. Monitoring the lesion (A) would be an unacceptable delay. Providing false reassurance (B) is outside the scope of practice. While avoiding the area (D) is prudent, it does not address the primary need for medical diagnosis.

Question 15

A 35-year-old female presents with diffuse muscle aches, profound fatigue, and symmetrical swelling and tenderness in the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints of both hands. She reports that her joints are stiff for more than an hour upon waking each morning. She has no history of trauma.

These findings are MOST characteristic of a condition that requires a referral to which type of specialist?

  1. A rheumatologist for a suspected systemic inflammatory disorder. (correct answer)
  2. An orthopedist for suspected osteoarthritis.
  3. A neurologist for suspected fibromyalgia.
  4. A primary care physician for a suspected viral infection.
Explanation: When you encounter a patient with joint symptoms, the key is distinguishing between mechanical joint problems and systemic inflammatory conditions by analyzing the pattern, timing, and associated symptoms. This patient's presentation points strongly toward rheumatoid arthritis, a systemic autoimmune disorder. The classic triad here is: symmetrical involvement of small joints (MCP and PIP), prolonged morning stiffness lasting over an hour, and systemic symptoms like fatigue and diffuse muscle aches. The bilateral, symmetrical pattern affecting the hands is particularly characteristic of inflammatory arthritis rather than wear-and-tear conditions. Choice A is correct because rheumatologists specialize in autoimmune and inflammatory joint diseases. This symptom constellation requires specialized testing like rheumatoid factor, anti-CCP antibodies, and inflammatory markers that rheumatologists are best equipped to interpret and manage. Choice B is wrong because osteoarthritis typically affects weight-bearing joints asymmetrically, causes brief morning stiffness (under 30 minutes), and rarely presents with systemic symptoms like fatigue. An orthopedist would be appropriate for mechanical joint problems, not inflammatory conditions. Choice C is incorrect because while fibromyalgia causes fatigue and muscle aches, it doesn't cause joint swelling or the specific symmetrical small joint involvement described here. Neurologists don't typically manage fibromyalgia primarily. Choice D misses the mark because viral arthritis is usually acute and self-limiting, not presenting with the chronic, symmetrical pattern described. Remember: Symmetrical small joint involvement + prolonged morning stiffness + systemic symptoms = think rheumatoid arthritis and rheumatology referral.

Question 16

A 48-year-old male with a history of intravenous drug use is being treated for severe, localized lumbar back pain. The pain is described as constant and is not relieved by rest or changes in position. He also reports having a low-grade fever, chills, and drenching night sweats for the past two weeks. Examination reveals exquisite tenderness with light percussion over the L3-L4 spinous processes, but neurological screening is negative.

The physical therapist should recognize this clinical picture as highly suspicious for which condition requiring urgent medical evaluation?

  1. Vertebral osteomyelitis or discitis. (correct answer)
  2. Ankylosing spondylitis.
  3. A large, acute herniated nucleus pulposus.
  4. Metastatic carcinoma of the spine.
Explanation: The correct answer is A. The combination of constitutional symptoms (fever, chills, night sweats), constant back pain unrelieved by rest, focal spine tenderness to percussion, and a significant risk factor (IV drug use) is a classic presentation for a spinal infection like vertebral osteomyelitis or discitis. This requires urgent medical evaluation and antibiotic therapy. A disc herniation (C) does not cause systemic signs of infection. Ankylosing spondylitis (B) is an inflammatory, not infectious, process. Metastasis (D) is a possibility, but the infectious signs and risk factor point more strongly toward osteomyelitis.

Question 17

A 55-year-old patient is receiving physical therapy on post-operative day 3 following a total knee arthroplasty. During ambulation training, the patient suddenly grabs his chest and complains of a sharp, stabbing pain that is worse when he takes a deep breath. He becomes extremely short of breath and tachycardic. The physical therapist notes his oxygen saturation has dropped from 97% to 88% on room air.

The therapist should immediately suspect which life-threatening post-operative complication?

  1. Atelectasis.
  2. Myocardial infarction.
  3. Anxiety or panic attack.
  4. Pulmonary embolism. (correct answer)
Explanation: The correct answer is D. Recent major orthopedic surgery (like a TKA) is a major risk factor for venous thromboembolism. The classic triad for a pulmonary embolism (PE) is the sudden onset of dyspnea, tachycardia, and pleuritic chest pain. The significant drop in oxygen saturation further supports this diagnosis. While a myocardial infarction (B) can cause chest pain and dyspnea, the pain is typically described as crushing pressure and is not pleuritic. Atelectasis (A) and anxiety (C) are less likely to cause this combination of sharp, pleuritic pain and profound, acute hypoxia.

Question 18

A 60-year-old male with a 50-pack-year smoking history presents with right shoulder pain radiating down the medial aspect of his arm to his fourth and fifth digits. He also complains of a new onset of right eyelid drooping, a constricted right pupil, and decreased sweating on the right side of his face. He has had a persistent, nagging cough for several months. A cervical spine screening examination, including Spurling's test, fails to reproduce any of his symptoms.

This cluster of signs and symptoms is a classic presentation of which condition requiring immediate medical referral?

  1. Pancoast tumor. (correct answer)
  2. Neurogenic thoracic outlet syndrome.
  3. Cervical radiculopathy affecting the C8-T1 nerve roots.
  4. Adhesive capsulitis with associated complex regional pain syndrome.
Explanation: When you encounter a patient with shoulder/arm pain combined with neurological symptoms affecting the face and eyes, think beyond typical musculoskeletal causes. This question tests your ability to recognize serious pathology requiring immediate medical attention. The key combination here is ulnar nerve distribution pain (medial arm to 4th/5th digits) with Horner's syndrome - the triad of eyelid drooping (ptosis), constricted pupil (miosis), and decreased facial sweating (anhidrosis). Add the patient's significant smoking history and persistent cough, and this points definitively to a Pancoast tumor. These apical lung tumors invade the brachial plexus (causing the C8-T1 pain pattern) and compress the sympathetic chain (causing Horner's syndrome). The negative cervical spine screening helps rule out spinal causes. Choice B (neurogenic thoracic outlet syndrome) can cause similar arm symptoms but wouldn't produce Horner's syndrome or be associated with persistent cough. Choice C (cervical radiculopathy) fits the pain pattern but again wouldn't explain the facial/eye symptoms, and Spurling's test was negative. Choice D (adhesive capsulitis with CRPS) doesn't match the specific nerve distribution or explain any of the neurological findings. For the NPTE, remember that Horner's syndrome in combination with upper extremity symptoms and a smoking history is a classic red flag pattern. Any time you see this triad - especially with C8-T1 distribution symptoms - think Pancoast tumor and immediate referral. Don't get distracted by the shoulder pain; focus on the complete symptom cluster.

Question 19

A 68-year-old male is being treated for chronic low back pain. He has had 5 sessions with moderate success. At his sixth visit, he reports his pain has worsened and is no longer responding to the exercises that previously provided relief. He also mentions an unintentional weight loss of 15 pounds over the past 3 months and complains of profound, generalized fatigue. His past medical history is significant for smoking 1 pack of cigarettes per day for 40 years.

Which course of action should the physical therapist prioritize?

  1. Modify the therapeutic exercise program to include more advanced core stabilization.
  2. Refer the patient back to his primary care physician for investigation of systemic disease. (correct answer)
  3. Add modalities such as heat and electrical stimulation to the current plan for pain management.
  4. Perform a neurological screening including a slump test and straight leg raise.
Explanation: The correct answer is B. The combination of red flags—unexplained weight loss, profound fatigue, a change in a chronic pain pattern (no longer responding to previously effective treatment), and a significant smoking history—is highly suggestive of an underlying systemic disease, most concerningly a malignancy (e.g., lung, pancreatic, multiple myeloma). The priority is to refer the patient for a medical workup to rule out a serious pathology. Continuing with routine physical therapy treatment (A, C, D) would be inappropriate and would delay a potentially critical diagnosis.

Question 20

A 64-year-old female is 6 months post-mastectomy with axillary lymph node dissection for right breast cancer and is attending physical therapy for shoulder rehabilitation. She has noticeable lymphedema in her right arm. During a session, she reports an insidious onset of swelling in her left leg over the past month. The therapist's examination of the left lower extremity reveals firm, non-pitting edema from the foot to the thigh. The patient has a history of a DVT in the left leg 2 years ago.

The combination of findings in the left lower extremity is MOST concerning for which condition, warranting communication with her oncologist?

  1. Bilateral lower extremity lymphedema secondary to chemotherapy.
  2. Congestive heart failure leading to dependent edema.
  3. Recurrence of deep vein thrombosis in the iliofemoral vein.
  4. Pelvic malignancy recurrence causing lymphatic or venous obstruction. (correct answer)
Explanation: The correct answer is D. In a patient with a history of cancer, the insidious onset of unilateral, non-pitting edema should raise high suspicion for an obstruction of the lymphatic or venous system by a tumor recurrence or metastatic disease in the pelvis or abdomen. While post-thrombotic syndrome from her old DVT (a component of C) is possible, the cancer history makes malignancy the most urgent concern to rule out. Congestive heart failure (B) typically causes bilateral, pitting edema. The edema is unilateral, not bilateral (A). The right arm lymphedema is an expected finding and acts as a distractor.
