Monitoring Patient ToleranceQuestion 1 of 20

A 68-year-old male is in a phase II cardiac rehabilitation program 8 weeks after a myocardial infarction. His medications include metoprolol and aspirin. During treadmill exercise, his vital signs change from a resting baseline of HR 62 bpm, BP 124/80 mm Hg, and SpO2 98% to HR 78 bpm, BP 145/94 mm Hg, and SpO2 97%. The patient reports a rating of perceived exertion (RPE) of 12/20 and denies chest pain. The telemetry monitor shows sinus rhythm with unifocal premature ventricular contractions (PVCs) at a rate of 4 per minute.

Based on these findings, which of the following is the MOST appropriate immediate action for the physical therapist to take?

Continue the exercise at the current intensity, as the patient's heart rate and RPE are within appropriate limits for a beta-blocked individual.
Stop the exercise immediately, lay the patient supine with legs elevated, and contact the supervising physician.
Reduce the treadmill intensity and continue to closely monitor blood pressure and the EKG rhythm for any changes.
Increase the treadmill grade slightly to determine if the PVCs become more frequent, which would confirm an ischemic response.

All questions

Question 1

A 68-year-old male is in a phase II cardiac rehabilitation program 8 weeks after a myocardial infarction. His medications include metoprolol and aspirin. During treadmill exercise, his vital signs change from a resting baseline of HR 62 bpm, BP 124/80 mm Hg, and SpO2 98% to HR 78 bpm, BP 145/94 mm Hg, and SpO2 97%. The patient reports a rating of perceived exertion (RPE) of 12/20 and denies chest pain. The telemetry monitor shows sinus rhythm with unifocal premature ventricular contractions (PVCs) at a rate of 4 per minute.

Based on these findings, which of the following is the MOST appropriate immediate action for the physical therapist to take?

  1. Continue the exercise at the current intensity, as the patient's heart rate and RPE are within appropriate limits for a beta-blocked individual.
  2. Stop the exercise immediately, lay the patient supine with legs elevated, and contact the supervising physician.
  3. Reduce the treadmill intensity and continue to closely monitor blood pressure and the EKG rhythm for any changes. (correct answer)
  4. Increase the treadmill grade slightly to determine if the PVCs become more frequent, which would confirm an ischemic response.
Explanation: The correct action is to reduce the intensity and continue monitoring. The key abnormal finding is the increase in diastolic blood pressure (DBP) by 14 mm Hg. A DBP rise of >10 mm Hg during exercise is an abnormal response, suggesting potential coronary ischemia. While the heart rate response is blunted by metoprolol and the RPE is acceptable, the DBP response is a sign of intolerance that warrants a reduction in intensity. Stopping exercise completely is not yet warranted as the patient is hemodynamically stable and asymptomatic, but continuing without modification is unsafe.

Question 2

A 70-year-old male is 3 days post-total knee arthroplasty and is performing gentle active-assistive range of motion exercises in bed. The patient has a history of peripheral vascular disease. He reports a sudden increase in calf pain, describing it as a deep, aching, and cramping sensation that is different from his incisional pain. The therapist notes localized swelling and warmth in the posterior calf, and the patient's calf measurement is 2.5 cm greater than the contralateral side.

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

  1. Continue with gentle ankle pump exercises to promote circulation and reduce the risk of venous stasis.
  2. Apply a hot pack to the calf to alleviate muscle cramping and improve patient comfort.
  3. Discontinue the intervention, keep the patient's leg elevated, and immediately notify the nursing staff and physician. (correct answer)
  4. Perform a Homan's sign test to confirm the presence of a deep vein thrombosis before taking further action.
Explanation: The patient's presentation—sudden onset of a different type of pain (deep ache/cramp), unilateral swelling, warmth, and tenderness—is highly suggestive of a deep vein thrombosis (DVT), a common post-operative complication. The Wells' clinical prediction rule for DVT would yield a high-probability score. Further activity or application of heat could potentially dislodge a thrombus. Homan's sign has poor diagnostic utility and is no longer recommended. The standard of care is to cease activity, position the patient for comfort without compressing the area, and immediately report the suspicion to the medical team for diagnostic workup (e.g., Doppler ultrasound).

Question 3

A physical therapist is using continuous ultrasound at 1 MHz, 1.5 W/cm² to the right shoulder capsule of a patient with adhesive capsulitis. The patient has a history of stable angina, which is managed with sublingual nitroglycerin as needed. Partway through the treatment, the patient reports the onset of left-sided jaw and neck pain, similar to their previous anginal episodes.

Which of the following actions should the therapist take IMMEDIATELY?

  1. Stop the ultrasound treatment, assess vital signs, and prepare to assist the patient with their prescribed nitroglycerin. (correct answer)
  2. Decrease the ultrasound intensity to 1.0 W/cm² and ask if the referred pain sensation subsides.
  3. Continue the treatment but move the sound head more quickly to avoid any periosteal irritation.
  4. Reposition the patient's arm to reduce stretch on the capsule and ask if that alleviates the jaw pain.
Explanation: The patient is reporting symptoms (jaw and neck pain) that are a classic anginal equivalent. The thermal effect of the ultrasound may have increased metabolic demand in the area, leading to an ischemic cardiac event. This is a medical emergency. The first step is to stop the intervention that is likely causing the problem. The therapist must then assess vital signs and be prepared to follow the protocol for an acute anginal attack, which includes administering nitroglycerin if prescribed and activating emergency services if the pain does not resolve. Modifying the treatment parameters or repositioning ignores the potential cardiac origin of the symptoms.

Question 4

A patient with relapsing-remitting multiple sclerosis is participating in an aquatic therapy session in a pool heated to 92°F (33°C). After 15 minutes of gentle exercise, the patient reports a significant increase in fatigue, blurred vision, and a feeling of heavy weakness in their legs, making it difficult to stand.

This adverse response is BEST explained by which of the following phenomena?

  1. Overwork weakness from excessive muscle activation.
  2. An acute exacerbation of the multiple sclerosis.
  3. A hypotensive response to the warm water environment.
  4. Uhthoff's phenomenon due to heat sensitivity. (correct answer)
Explanation: When you encounter a multiple sclerosis patient experiencing rapid symptom worsening in a heated environment, think about temperature-related neurological phenomena rather than structural damage or general medical complications. The correct answer is D) Uhthoff's phenomenon. This well-documented condition occurs when elevated body temperature temporarily worsens neurological symptoms in people with multiple sclerosis or other demyelinating diseases. Heat slows nerve conduction in already-damaged, demyelinated axons, causing existing symptoms to become more pronounced. The patient's rapid onset of fatigue, visual disturbances, and leg weakness after just 15 minutes in 92°F water is classic for this phenomenon. Importantly, these symptoms are temporary and reversible once body temperature normalizes. Option A) overwork weakness typically develops over hours to days from excessive exercise, not within 15 minutes of gentle activity. Option B) an acute exacerbation involves actual inflammation and new tissue damage, which wouldn't occur so rapidly or be directly triggered by brief heat exposure. Option C) hypotensive response would primarily cause dizziness, lightheadedness, or fainting rather than the specific neurological symptoms described (blurred vision, leg weakness). For the NPTE, remember that rapid neurological symptom worsening in MS patients exposed to heat strongly suggests Uhthoff's phenomenon. This is why aquatic therapy protocols for MS patients typically recommend cooler pool temperatures (83-88°F) and careful monitoring. Always consider temperature as a reversible trigger for symptom exacerbation in demyelinating diseases.

Question 5

A physical therapist is initiating a tilt table protocol for a patient with a C5 complete spinal cord injury. After elevating the table to 60 degrees, the patient reports a pounding headache. The therapist notes that the patient's face is flushed, and there is significant piloerection on the upper extremities. The patient's blood pressure is 170/110 mm Hg, and heart rate is 50 bpm.

Which of the following actions should the physical therapist take FIRST?

  1. Lower the tilt table to 30 degrees and reassess the patient's symptoms and vital signs.
  2. Immediately return the tilt table to the horizontal position and check for any noxious stimuli below the level of the lesion. (correct answer)
  3. Maintain the current position and administer prescribed emergency antihypertensive medication.
  4. Activate the emergency response system and begin preparations for cardiopulmonary resuscitation.
Explanation: The patient is exhibiting classic signs and symptoms of autonomic dysreflexia (pounding headache, hypertension, bradycardia, flushing above the lesion level), a medical emergency. The first and most critical action is to sit the patient upright to help lower blood pressure via orthostatic effects. However, since the patient is on a tilt table, the immediate priority is to lower the table to horizontal and then, if possible, sit the patient up. Simultaneously, the therapist must identify and remove the offending noxious stimulus, which could be a kinked catheter, tight clothing, or fecal impaction. Lowering the table only partially or administering medication before removing the stimulus is incorrect.

Question 6

A 45-year-old female with Guillain-Barré syndrome is in the subacute phase of rehabilitation. The plan of care includes progressive-resistive exercises for lower extremity strengthening. During a session of seated knee extension with a light resistance band, the patient successfully completes two sets of 10 repetitions. On the third set, the therapist observes that the patient's active range of motion has decreased by 15 degrees and the patient reports increased muscle soreness 24 hours later that does not resolve within the next day.

This patient's response is MOST indicative of which of the following phenomena?

  1. A normal training response indicating appropriate muscle fatigue and adaptation.
  2. The onset of Uhthoff's phenomenon, requiring immediate cooling measures.
  3. Overwork weakness, necessitating a reduction in exercise intensity and volume. (correct answer)
  4. A relapse of the acute inflammatory phase of the disease requiring medical consultation.
Explanation: The key signs presented—a decline in strength and function (decreased ROM) during the session, and delayed-onset muscle soreness that persists for more than 24-48 hours—are hallmark indicators of overwork weakness in patients with neuromuscular diseases like Guillain-Barré syndrome. This occurs when the demands placed on partially denervated muscles exceed their metabolic and physiological capacity, leading to a temporary or permanent decline in strength. The appropriate response is to reduce the intensity and volume of exercise to a level that does not produce these signs.

Question 7

A 55-year-old female is receiving treatment for right upper extremity lymphedema secondary to a mastectomy. During a session of complete decongestive therapy that includes manual lymphatic drainage and multi-layer compression bandaging, the patient reports a new onset of mild shortness of breath and a non-productive cough. Auscultation reveals faint crackles at the lung bases bilaterally.

What is the MOST likely cause of these symptoms, and what is the therapist's best course of action?

  1. An allergic reaction to the bandage materials; remove the bandages and apply a hypoallergenic lotion.
  2. Increased fluid load on the central circulation; stop treatment, elevate the head of the bed, and contact her physician. (correct answer)
  3. Exercise-induced bronchospasm; administer a rescue inhaler and monitor her response.
  4. A normal sensation of pressure from the bandages; reassure the patient and continue with the treatment.
Explanation: Complete decongestive therapy mobilizes a large volume of lymphatic fluid from the periphery back into the central circulation. In a patient with underlying or latent cardiac or renal insufficiency, this can overwhelm the heart's ability to manage the increased preload, leading to acute fluid overload and congestive heart failure. The symptoms of shortness of breath, cough, and crackles at the lung bases are classic signs of pulmonary edema. This is a potentially serious complication requiring immediate cessation of treatment, positioning to decrease cardiac workload (elevating the head), and prompt medical consultation.

Question 8

A physical therapist is working with a patient with Parkinson's disease on sit-to-stand transfers. The patient took their carbidopa-levodopa medication 30 minutes prior to the session. After two successful transfers, the patient reports feeling dizzy and lightheaded upon standing. The therapist measures the patient's blood pressure as 110/70 mm Hg while sitting and 85/55 mm Hg within one minute of standing.

Which of the following interventions is the MOST appropriate immediate response?

  1. Have the patient march in place to activate the muscle pump and increase venous return.
  2. Return the patient to a seated position and elevate their legs to above heart level. (correct answer)
  3. Provide the patient with a glass of water and continue with the transfers once the dizziness subsides.
  4. Check the patient's medication schedule to ensure they did not miss a dose of carbidopa-levodopa.
Explanation: The patient is experiencing symptomatic orthostatic hypotension, defined as a drop in systolic blood pressure of ≥20 mm Hg or diastolic blood pressure of ≥10 mm Hg within three minutes of standing. This is a common side effect of dopaminergic medications like carbidopa-levodopa, which can peak around 30-60 minutes after ingestion. The most immediate and safest action is to return the patient to a seated or supine position to restore cerebral perfusion and prevent syncope or a fall. Elevating the legs can further assist with venous return. Other interventions like ankle pumps can be done once the patient is safely seated, but the priority is to get them out of the upright position.

Question 9

A 32-year-old female who is 30 weeks pregnant is performing a bridging exercise in the supine position. After the second repetition, she reports feeling lightheaded, nauseous, and short of breath. The physical therapist observes that she has become pale and diaphoretic.

Which physiological mechanism is the MOST likely cause of the patient's symptoms?

  1. A vagal response triggered by the exertion of the bridging exercise.
  2. Gestational hypoglycemia due to increased metabolic demands of the fetus.
  3. Anxiety-induced hyperventilation related to the exercise.
  4. Compression of the inferior vena cava by the gravid uterus. (correct answer)
Explanation: When you encounter pregnancy-related symptoms during exercise, especially in the second or third trimester, always consider the mechanical effects of the enlarged uterus on surrounding structures. The correct answer is D because supine hypotensive syndrome (also called aortocaval compression syndrome) is a well-documented complication after 20 weeks of pregnancy. When a pregnant woman lies supine, the heavy gravid uterus compresses the inferior vena cava against the vertebral column, reducing venous return to the heart. This decreases cardiac output by up to 25-30%, causing the classic triad of hypotension, lightheadedness, and compensatory tachycardia. The pale, diaphoretic appearance reflects the body's sympathetic response to decreased perfusion. Option A is incorrect because a vagal response would typically cause bradycardia and would be unusual after just two repetitions of a low-intensity exercise like bridging. Option B misses the mark because gestational hypoglycemia develops gradually over time and wouldn't cause such acute, position-related symptoms that appeared immediately during supine positioning. Option C fails to explain why the symptoms occurred specifically in supine position rather than when standing or sitting, and anxiety-induced hyperventilation typically presents with different symptoms like tingling and muscle cramping. NPTE Strategy: Questions about pregnant patients exercising in supine position after 20 weeks gestation are testing your knowledge of supine hypotensive syndrome. Always consider positional modifications (left side-lying or semi-reclined) as the immediate intervention, and remember this contraindication is absolute in the second and third trimesters.

Question 10

A 62-year-old patient with type 2 diabetes and peripheral neuropathy is participating in a moderate-intensity aerobic exercise program. Midway through a 20-minute session on a stationary bicycle, the patient becomes confused and irritable. The therapist notes that the patient's skin is pale and clammy, and they appear uncoordinated in their movements.

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

  1. Hyperglycemia, requiring immediate cessation of exercise and administration of insulin.
  2. Silent myocardial ischemia, requiring activation of the emergency response system.
  3. Heat exhaustion, requiring removal to a cool environment and fluid replacement.
  4. Hypoglycemia, requiring immediate administration of a fast-acting carbohydrate. (correct answer)
Explanation: When you encounter exercise complications in patients with diabetes, you need to quickly differentiate between metabolic emergencies and other conditions based on the clinical presentation and timing. The key signs here point to hypoglycemia: confusion, irritability, pale and clammy skin, and uncoordination during moderate exercise. These are classic symptoms of low blood sugar, which can develop rapidly during physical activity as muscles consume glucose faster than it can be replenished. The timing (midway through exercise) and neurological symptoms (confusion, poor coordination) are hallmark features of hypoglycemia. Option D is correct because hypoglycemia requires immediate treatment with fast-acting carbohydrates like glucose tablets, juice, or candy to rapidly raise blood sugar levels. Option A is wrong because hyperglycemia typically presents with different symptoms (excessive thirst, frequent urination, fatigue) and develops more gradually. The pale, clammy skin and acute confusion are not characteristic of high blood sugar. Option B is incorrect because while silent MI is a concern in diabetic patients, the neurological symptoms (confusion, irritability) and skin changes are more consistent with metabolic causes rather than cardiac ischemia, which would more likely present with chest discomfort, shortness of breath, or fatigue. Option C is wrong because heat exhaustion typically involves elevated body temperature, excessive sweating, and occurs in hot environments. The pale, clammy presentation with neurological changes points away from heat-related illness. Remember: In diabetic patients exercising, sudden onset of confusion with pale, clammy skin should make you think hypoglycemia first. Always have fast-acting carbohydrates readily available during exercise sessions.

Question 11

A patient is 4 days post-coronary artery bypass graft (CABG) surgery and is ambulating in the hallway with telemetry monitoring. The physical therapist notes on the monitor that the patient's rhythm has changed from normal sinus to a run of 4 consecutive wide, bizarre-looking QRS complexes. The patient suddenly reports feeling very dizzy and grabs onto the railing.

The EKG finding and the patient's symptoms are MOST indicative of which of the following events?

  1. A new onset of atrial fibrillation with rapid ventricular response.
  2. A short run of non-sustained ventricular tachycardia. (correct answer)
  3. Frequent multifocal premature ventricular contractions.
  4. ST-segment elevation indicating an acute myocardial infarction.
Explanation: A run of three or more consecutive PVCs is defined as ventricular tachycardia (V-tach). The description of wide, bizarre QRS complexes is characteristic of this arrhythmia. Because it lasted for only 4 beats, it is non-sustained. However, V-tach can compromise cardiac output, leading to symptoms like dizziness or syncope, and can degenerate into a more lethal arrhythmia. This is a critical event. The therapist should have the patient stop, sit down immediately, and call for immediate medical assistance. Atrial fibrillation would show an irregularly irregular rhythm with narrow QRS complexes. ST elevation is an ischemic sign, not a description of the QRS complex itself.

Question 12

A patient in the intensive care unit is mechanically ventilated with a positive end-expiratory pressure (PEEP) of 10 cm H2O. A physical therapist is performing passive range of motion to the lower extremities. The patient's heart rate increases from 90 to 125 bpm, and their mean arterial pressure (MAP) drops from 75 to 55 mm Hg. The patient remains sedated and unresponsive.

The MOST likely cause for this acute hemodynamic change is which of the following?

  1. Decreased venous return and cardiac output exacerbated by the PEEP. (correct answer)
  2. An adverse response to the sedative medication.
  3. A dislodged endotracheal tube causing hypoxia.
  4. Autonomic dysreflexia triggered by the range of motion exercises.
Explanation: When you encounter hemodynamic changes in mechanically ventilated ICU patients, think about how positive pressure ventilation affects cardiovascular function. PEEP increases intrathoracic pressure, which can significantly impact venous return and cardiac output. The patient's presentation—tachycardia (90→125 bpm) with hypotension (MAP 75→55 mmHg)—indicates compensatory mechanisms trying to maintain cardiac output despite decreased venous return. The elevated PEEP of 10 cm H2O creates sustained positive intrathoracic pressure that impedes venous return to the right ventricle. When you add physical therapy movements that may further compromise venous return (through positioning or increased intra-abdominal pressure), the cardiovascular system can decompensate rapidly. This makes option A correct. Option B is unlikely because sedative medications typically cause gradual hemodynamic changes, not acute decompensation during physical therapy. The timing doesn't match a medication effect. Option C would present with obvious signs like decreased oxygen saturation, visible tube displacement, or loss of breath sounds—none of which are mentioned. A dislodged ET tube would cause immediate respiratory distress that wouldn't be missed. Option D is incorrect because autonomic dysreflexia occurs in patients with spinal cord injuries above T6, and this condition isn't mentioned. Additionally, autonomic dysreflexia typically causes severe hypertension, not hypotension. Remember: In mechanically ventilated patients with high PEEP, always consider cardiovascular compromise when you see acute tachycardia with hypotension. The positive pressure ventilation directly affects preload, making these patients hemodynamically fragile during interventions.

Question 13

A patient with end-stage renal disease (ESRD) is seen for physical therapy on a non-dialysis day. The plan includes light strengthening and endurance training. During the session, the patient develops muscle twitching, cramping, and reports paresthesias around their mouth. An EKG strip on the monitor shows peaked T waves.

This constellation of signs and symptoms is MOST indicative of a critical imbalance of which electrolyte?

  1. Hyperkalemia (correct answer)
  2. Hypocalcemia
  3. Hyponatremia
  4. Hypermagnesemia
Explanation: When you encounter electrolyte imbalance questions on the NPTE, focus on the classic symptom clusters and any EKG changes mentioned. These clinical presentations have distinctive patterns that help you quickly identify the specific electrolyte involved. The combination of muscle twitching, cramping, paresthesias, and peaked T waves on EKG is the textbook presentation for hyperkalemia. Peaked T waves are particularly diagnostic - they're the earliest and most reliable EKG finding in potassium excess. ESRD patients are especially prone to hyperkalemia because their kidneys cannot effectively excrete potassium, and this risk increases between dialysis sessions when potassium continues to accumulate. Option A (Hyperkalemia) is correct because it matches all the presented symptoms perfectly. The neuromuscular irritability (twitching, cramping) occurs as elevated potassium affects nerve and muscle cell membrane potentials, while the peaked T waves reflect cardiac conduction changes. Option B (Hypocalcemia) would cause similar neuromuscular symptoms but typically presents with Chvostek's or Trousseau's signs and QT prolongation on EKG, not peaked T waves. Option C (Hyponatremia) primarily causes neurological symptoms like confusion, headache, and seizures rather than the muscle cramping and EKG changes described. Option D (Hypermagnesemia) typically causes muscle weakness and depressed reflexes rather than twitching and cramping, plus it would show prolonged PR intervals on EKG. Remember: Peaked T waves + neuromuscular irritability in a renal patient = hyperkalemia. This is a medical emergency requiring immediate intervention, so recognizing this pattern is crucial for patient safety.

Question 14

An 80-year-old female with severe osteoporosis is participating in a group exercise class that includes gentle resistance training. While performing a seated rowing exercise with a light resistance band, she experiences a sudden, sharp, and localized pain in her mid-thoracic spine. She is unable to continue with the exercise and has palpable tenderness over the T8 spinous process.

Given the patient's history and the acute onset of symptoms, what is the MOST likely cause of her pain?

  1. A thoracic muscle strain from overexertion.
  2. A compression fracture of a thoracic vertebra. (correct answer)
  3. Costochondritis from the movement of the rib cage.
  4. An acute herniation of a thoracic intervertebral disc.
Explanation: In a patient with severe osteoporosis, even minor forces or movements (like the pulling motion of a rowing exercise) can be sufficient to cause a vertebral compression fracture. The presentation of sudden, sharp, localized spinal pain with point tenderness is a classic sign. Muscle strains are possible but typically do not present with such acute, sharp pain and focal bony tenderness. Thoracic disc herniations are rare and would likely have a radicular component. Costochondritis pain is typically located more anteriorly at the costosternal joints. The high suspicion for fracture requires cessation of activity and referral for medical evaluation.

Question 15

A patient with chronic obstructive pulmonary disease (COPD) is performing diaphragmatic breathing and pursed-lip breathing exercises. During the intervention, the therapist observes that the patient's upper chest and sternocleidomastoid muscles are contracting paradoxically during inspiration, and the patient's respiratory rate has increased from 18 to 28 breaths per minute. The patient's SpO2 remains stable at 91% on 2L of supplemental oxygen.

Which of the following is the MOST appropriate interpretation and subsequent action by the therapist?

  1. The patient is experiencing acute respiratory failure; activate the emergency response system immediately.
  2. This is a normal response to the increased work of breathing; continue the exercises with verbal cueing to relax.
  3. The patient is demonstrating respiratory muscle fatigue; stop the exercise and allow the patient to rest in a forward-leaning position. (correct answer)
  4. The patient is hyperventilating due to anxiety; switch to a relaxation technique such as guided imagery.
Explanation: The combination of increased respiratory rate, paradoxical breathing pattern (inward movement of the abdomen and excessive use of accessory muscles during inspiration), indicates significant respiratory muscle fatigue. The diaphragm, the primary muscle of inspiration, is failing, and the body is compensating with inefficient accessory muscles. While the SpO2 is stable, these physical signs indicate that the current activity is too demanding. The most appropriate action is to stop the intervention and place the patient in a position that optimizes respiratory mechanics and reduces the work of breathing, such as a forward-leaning (tripod) position.

Question 16

A patient with a traumatic brain injury (Rancho Los Amigos Level IV) becomes increasingly agitated during a bedside session focused on passive range of motion. The patient begins to thrash, and the therapist notes profuse diaphoresis, tachycardia (HR 130 bpm), hypertension (BP 180/100 mm Hg), and extensor posturing of the lower extremities.

This cluster of signs is MOST consistent with which of the following neurologic phenomena?

  1. Autonomic dysreflexia secondary to a noxious stimulus.
  2. A complex partial seizure originating in the temporal lobe.
  3. Paroxysmal sympathetic hyperactivity, also known as 'sympathetic storming'. (correct answer)
  4. Malignant hyperthermia triggered by the physical activity.
Explanation: Paroxysmal sympathetic hyperactivity (PSH), or 'sympathetic storming,' is a syndrome common after severe traumatic brain injury. It is characterized by episodes of increased sympathetic nervous system activity, leading to tachycardia, hypertension, tachypnea, diaphoresis, and dystonic posturing. These episodes are often triggered by external stimuli, including routine care like passive range of motion. Autonomic dysreflexia is associated with spinal cord injury above T6. Seizure activity would typically involve more specific motor manifestations or altered consciousness. Malignant hyperthermia is a rare reaction to anesthesia.

Question 17

A physical therapist is applying intermittent mechanical lumbar traction to a patient with a posterolateral disc herniation and right-sided S1 radiculopathy. The initial pull is set to 25% of the patient's body weight. After 5 minutes, the patient reports that the pain in their calf has completely resolved, but they now feel a new sensation of numbness in the saddle region.

What is the MOST appropriate action for the therapist to take?

  1. Continue the traction, as the resolution of distal pain indicates successful centralization.
  2. Increase the traction force by 5-10 pounds to further reduce the disc herniation.
  3. Immediately stop the traction, place the patient in a neutral position, and perform an urgent neurological screen. (correct answer)
  4. Document the change in sensation and continue for the full duration, reassessing at the end of the session.
Explanation: The new onset of saddle anesthesia is a significant red flag for cauda equina syndrome, a medical emergency caused by compression of the nerve roots at the end of the spinal cord. While the resolution of calf pain might seem like centralization, the appearance of this specific symptom is an ominous sign that indicates worsening nerve compression at a critical level. The standard of care is to stop the intervention immediately, assess for other signs of cauda equina syndrome (e.g., changes in bowel/bladder function, perineal sensation), and notify the referring physician or emergency services urgently.

Question 18

A physical therapist is using neuromuscular electrical stimulation (NMES) for quadriceps strengthening on a patient with chronic atrial fibrillation who is medically managed and stable. During the third set of contractions, the patient states, "I feel like my heart is fluttering and skipping beats." The patient appears anxious but denies chest pain or shortness of breath. The therapist palpates a radial pulse and confirms an irregularly irregular rhythm.

What is the physical therapist's MOST appropriate immediate action?

  1. Discontinue the NMES treatment, monitor the patient's vital signs, and document the subjective report. (correct answer)
  2. Reassure the patient that this sensation is common and related to the electrical current.
  3. Continue the NMES but decrease the intensity to a level below which the patient feels symptoms.
  4. Immediately activate the emergency response system as this indicates a conversion to ventricular tachycardia.
Explanation: When treating patients with known cardiac conditions, you must always prioritize patient safety and recognize when symptoms may indicate cardiac involvement, even during routine treatments like NMES. Answer A is correct because it follows proper clinical reasoning for a patient with known atrial fibrillation reporting new cardiac symptoms. Although the patient has chronic a-fib and the irregular pulse may be baseline, the patient's subjective report of increased symptoms ("fluttering and skipping") during treatment requires immediate assessment. Discontinuing the potential trigger (NMES), monitoring vital signs, and documenting creates a safe environment for proper evaluation. This doesn't assume an emergency, but appropriately responds to a change in the patient's condition. Answer B is wrong because dismissing cardiac symptoms in a patient with known heart disease is dangerous. Even if NMES can sometimes cause sensations, you cannot assume the patient's symptoms are benign without proper assessment. Answer C is incorrect because continuing any treatment when a cardiac patient reports worsening symptoms ignores basic safety principles. Reducing intensity doesn't eliminate the potential cardiac trigger or allow for proper evaluation. Answer D represents overreaction. An irregularly irregular rhythm is consistent with the patient's known atrial fibrillation, not ventricular tachycardia. The patient is stable without chest pain or dyspnea, so emergency activation isn't warranted based on current presentation. Remember: When patients with cardiac conditions report new or worsening cardiac symptoms during treatment, always stop the intervention first, assess thoroughly, and document. You can always resume treatment once safety is confirmed.

Question 19

A 24-year-old collegiate football player is participating in pre-season training in a hot, humid environment. After a series of intense plyometric drills, he complains of severe bilateral thigh pain, profound weakness, and notes that his urine is dark, almost brown, in color. He appears confused and is nauseous.

The patient's presentation is MOST concerning for which of the following conditions?

  1. Severe delayed onset muscle soreness (DOMS).
  2. Bilateral quadriceps tendon rupture.
  3. Acute heat stroke with dehydration.
  4. Exertional rhabdomyolysis. (correct answer)
Explanation: The classic triad of symptoms for rhabdomyolysis is muscle pain (myalgia), weakness, and dark (tea- or cola-colored) urine due to myoglobinuria. This condition involves the rapid breakdown of skeletal muscle tissue, releasing damaging proteins into the bloodstream, which can lead to acute kidney injury. The altered mental status is also a severe sign. This is a medical emergency requiring immediate referral. While heat stroke and dehydration are likely co-present, the specific combination with severe myalgia and dark urine points directly to rhabdomyolysis as the primary emergent diagnosis.

Question 20

A physical therapist is managing a patient's diabetic foot ulcer with negative pressure wound therapy (NPWT). During a dressing change, the therapist notes that the exudate in the collection canister has increased significantly in volume and has changed from serosanguinous to bright red. The wound bed itself appears to be actively bleeding.

What is the MOST appropriate immediate action for the therapist?

  1. Reinforce the dressing, increase the pressure setting on the NPWT device, and notify the physician at the next opportunity.
  2. Disconnect the NPWT device, apply direct pressure to the wound with a sterile dressing, and seek immediate medical assistance. (correct answer)
  3. Irrigate the wound with sterile saline to better visualize the source of the bleeding before taking further action.
  4. Document the findings and switch to a different type of wound dressing, such as an alginate, to help with hemostasis.
Explanation: A sudden change to frank, bright red bleeding is a sign of active hemorrhage, a rare but serious complication of NPWT, especially if a blood vessel has eroded. Continuing NPWT would exacerbate the bleeding. The immediate priority is to control the hemorrhage. This requires disconnecting the suction, applying direct pressure to the wound, and obtaining immediate medical help. Irrigating the wound or simply switching dressings without controlling the bleed and getting a medical evaluation would be unsafe and inappropriate.
