All questions

Question 1

A patient on digoxin and furosemide reports nausea and yellow vision. What is the likely cause?

  1. Hypokalemic digoxin toxicity (correct answer)
  2. Furosemide-induced ototoxicity
  3. Hyperkalemia from digoxin
  4. Furosemide-induced hypovolemia
Explanation: Nausea and yellow vision are hallmark symptoms of digoxin toxicity. Furosemide depletes potassium, and low potassium potentiates digoxin's effects, so this is hypokalemic digoxin toxicity. Furosemide-induced ototoxicity is the tempting wrong answer because it involves furosemide, but it causes hearing loss or tinnitus, not yellow vision.

Question 2

A patient on propranolol has a blunted heart-rate response. Which exercise target is most valid?

  1. By heart-rate reserve
  2. By perceived exertion (correct answer)
  3. By metabolic equivalents
  4. By pretesting vital signs
Explanation: Because propranolol blunts the heart-rate response, any target based on heart rate is unreliable. Perceived exertion reflects your effort and symptoms and remains valid under beta blockade. The tempting error is heart-rate reserve: it is a standard exercise target, but it depends on HR, so it would give a falsely low or misleading intensity.

Question 3

A patient on long-term prednisone has atraumatic hip pain. What should be ruled out?

  1. Avascular necrosis of the hip (correct answer)
  2. Adrenal insufficiency crisis
  3. Greater trochanteric bursitis
  4. Lumbar radicular referral
Explanation: Long-term prednisone is a major risk factor for avascular necrosis, and atraumatic hip pain is its classic presentation, so that must be ruled out first. The tempting wrong answer is adrenal insufficiency crisis, but that causes systemic findings such as hypotension, fatigue, and nausea, not isolated deep hip pain.

Question 4

A patient on warfarin has INR 3.2 and new calf pain. What should the PT do?

  1. Start gentle strengthening
  2. Proceed with aerobic training
  3. Apply heat and gentle stretch
  4. Screen for DVT before exercise (correct answer)
Explanation: New calf pain in a patient on warfarin is a red flag for deep vein thrombosis, especially with an INR of 3.2. You must screen for DVT before any exercise or local treatment. The tempting mistake is treating it as a muscle strain with heat and gentle stretching, which could risk clot dislodgment. Screen first.

Question 5

A patient on insulin and metformin has glucose 58 mg/dL before PT. What should be done first?

  1. Start low-intensity exercise
  2. Delay exercise 30 minutes
  3. Treat with 15 g oral glucose (correct answer)
  4. Take supplemental insulin
Explanation: A glucose of 58 mg/dL is hypoglycemia. Before any PT, you must raise blood sugar first, so give 15 g of fast-acting oral glucose. Low-intensity exercise is tempting because exercise lowers glucose, but in hypoglycemia it risks driving glucose even lower. Delaying exercise or taking insulin won't correct the current low.

Question 6

A 66-year-old post–TKA receives oxycodone; during transfers shows impaired attention and delayed balance reactions. Based on the case, what is the primary concern of oxycodone in PT examination?

  1. Increased fall risk from sedation and slowed responses (correct answer)
  2. Improved proprioception leading to safer independent ambulation
  3. Higher muscle tone requiring tone-inhibiting techniques
  4. Reduced edema by enhancing venous return during exercise
Explanation: This question tests understanding of the pharmacological impact on physical therapy examination, prognosis, and care planning. Pharmacological management affects physical therapy by altering patient response, exercise tolerance, and healing rates. In the vignette, oxycodone is used, affecting attention and balance reactions. Choice A is correct because it reflects the increased fall risk from opioid sedation. Choice B is incorrect because it misinterprets the drug's effect, as oxycodone impairs rather than improves proprioception. To help students: Emphasize understanding drug mechanisms and their clinical implications in PT. Encourage reviewing pharmacology basics and patient case studies.

Question 7

A 70-year-old post–TKA uses oxycodone; PT finds RR 10/min, drowsiness, and poor participation. Based on the case, what is the primary concern of oxycodone in PT examination?

  1. Respiratory depression and sedation limiting safe activity (correct answer)
  2. Increased aerobic capacity allowing aggressive interval training
  3. Improved balance reactions enabling unguarded stair training
  4. Elevated muscle tone requiring prolonged stretching only
Explanation: This question tests understanding of the pharmacological impact on physical therapy examination, prognosis, and care planning. Pharmacological management affects physical therapy by altering patient response, exercise tolerance, and healing rates. In the vignette, oxycodone is used, affecting respiration and participation. Choice A is correct because it reflects respiratory depression and sedation limiting activity. Choice B is incorrect because it misinterprets the drug's effect, as opioids decrease rather than increase aerobic capacity. To help students: Emphasize understanding drug mechanisms and their clinical implications in PT. Encourage reviewing pharmacology basics and patient case studies.

Question 8

A 62-year-old with hypertension takes metoprolol; HR stays 58–62 bpm during cycling though RPE rises. Which pharmacological effect should be most considered when planning therapy?

  1. Blunted HR response requires using RPE and symptoms (correct answer)
  2. Marked bronchodilation allows higher aerobic intensity
  3. Improved anaerobic power permits maximal interval training
  4. Increased resting HR requires longer warm-up periods
Explanation: This question tests understanding of the pharmacological impact on physical therapy examination, prognosis, and care planning. Pharmacological management affects physical therapy by altering patient response, exercise tolerance, and healing rates. In the vignette, metoprolol is used, affecting heart rate response during aerobic exercise. Choice A is correct because it reflects the blunted HR response from beta-blockers, necessitating alternative monitoring like RPE. Choice B is incorrect because it overlooks the drug's effect, as beta-blockers do not cause marked bronchodilation. To help students: Emphasize understanding drug mechanisms and their clinical implications in PT. Encourage reviewing pharmacology basics and patient case studies.

Question 9

A 45-year-old male with a transtibial amputation is managing phantom limb pain with pregabalin. He has been working with a prosthetist on a new socket design. He reports to physical therapy that his pain is much improved, but his residual limb now feels "puffy" and the new prosthesis is suddenly too tight. He also notes a 10-pound weight gain over the last six weeks without any change in diet.

The physical therapist should recognize these new findings as most likely being:

  1. A result of a poorly fitting prosthetic socket causing localized inflammation and fluid retention in the residual limb.
  2. Indicative of congestive heart failure, requiring an immediate referral to a cardiologist for an echocardiogram.
  3. Common side effects of pregabalin, specifically peripheral edema and weight gain, which require collaboration with the physician and prosthetist. (correct answer)
  4. A sign of heterotopic ossification in the residual limb, which is preventing proper fluid return and causing the swelling.
Explanation: Peripheral edema and weight gain are well-documented and common side effects of pregabalin. The combination of systemic weight gain and localized swelling (edema) in the residual limb strongly points to a pharmacological cause. This is a critical issue as it directly impacts prosthetic fit and function. The best course of action is to manage the edema and communicate with the physician and prosthetist. (A) is less likely given the concurrent systemic weight gain. (B) is a possibility in the differential, but the medication is a much more direct and probable cause. (D) Heterotopic ossification would present with localized warmth, pain, and a hard end-feel, not the "puffy" swelling described.

Question 10

A 61-year-old with hypertension on metoprolol reports unusual fatigue early in treadmill test; HR rises minimally. How does the medication metoprolol affect the patient's exercise prescription in the provided case?

  1. Use symptom/RPE-guided intensity rather than HR targets (correct answer)
  2. Expect higher peak HR, so increase target HR range
  3. Assume no effect on HR, so rely on age-predicted HRmax
  4. Avoid warm-up because beta-blockers speed oxygen delivery
Explanation: This question tests understanding of the pharmacological impact on physical therapy examination, prognosis, and care planning. Pharmacological management affects physical therapy by altering patient response, exercise tolerance, and healing rates. In the vignette, metoprolol is used, affecting heart rate and causing early fatigue. Choice A is correct because it reflects using alternative intensity measures due to blunted HR. Choice B is incorrect because it overlooks the drug's effect, as beta-blockers lower rather than raise peak HR. To help students: Emphasize understanding drug mechanisms and their clinical implications in PT. Encourage reviewing pharmacology basics and patient case studies.

Question 11

A 65-year-old male with type 2 diabetes and peripheral neuropathy is being treated for a urinary tract infection with ciprofloxacin. During a physical therapy session for gait training, he reports the sudden onset of a sharp, localized pain in his right posterior lower leg, about 2 inches above the calcaneus. There was no specific trauma.

What is the MOST appropriate immediate action for the physical therapist?

  1. Apply ice to the area and perform gentle calf stretching to address a suspected muscle strain.
  2. Assume the pain is a new manifestation of his diabetic neuropathy and continue with modified, non-weight-bearing activities.
  3. Immediately place the patient in a non-weight-bearing status, hold all further activity, and notify the referring physician of suspected tendinopathy. (correct answer)
  4. Complete the gait training session, advising the patient to push through the pain, and document the new symptom in the daily note.
Explanation: Fluoroquinolone antibiotics, such as ciprofloxacin, carry an FDA black box warning for an increased risk of tendonitis and tendon rupture, particularly of the Achilles tendon. The patient's new, sharp, localized pain in that area is a major red flag for this serious adverse effect. The most appropriate and safe action is to immediately cease all activity that loads the tendon and urgently communicate this finding to the physician. (A) is dangerous as stretching or loading a potentially damaged tendon could precipitate a full rupture. (B) incorrectly attributes the symptom to neuropathy while ignoring the more likely pharmacological cause. (D) is negligent and could lead to significant patient harm.

Question 12

A 78-year-old female with severe osteoporosis is referred to physical therapy for right-sided posterior canal BPPV. Her medication list includes alendronate, taken once weekly. The therapist plans to perform the Epley maneuver.

Which of the following pharmacological considerations is MOST critical for the therapist to address before initiating the maneuver?

  1. Ask the patient if she took her alendronate this morning, as the maneuver is contraindicated for at least 30-60 minutes post-ingestion. (correct answer)
  2. Determine if the patient experiences dizziness as a side effect of alendronate, as this may be confused with vestibular symptoms.
  3. Assess for signs of atypical femur fracture, a rare side effect of the medication, before performing any lower extremity movements.
  4. Confirm that the patient is not taking any calcium supplements, as they interfere with the absorption and effectiveness of alendronate.
Explanation: Bisphosphonates like alendronate can cause severe esophageal irritation and ulceration if reflux occurs. To prevent this, patients must remain in an upright position for at least 30-60 minutes after taking the medication. The Epley maneuver requires moving the patient into supine and head-down (Trendelenburg) positions, which would be dangerous if the medication was recently ingested. Therefore, the therapist must confirm the timing of the dose before proceeding. (B) is a minor consideration compared to the risk of esophageal damage. (C) is a valid long-term concern but not an immediate contraindication for a canalith repositioning maneuver. (D) is a matter of medication efficacy for the physician to manage, not a direct safety contraindication for the PT procedure.

Question 13

A 45-year-old patient with a T4 spinal cord injury has an intrathecal baclofen pump for management of severe lower extremity spasticity. He is brought to his therapy session by his caregiver, who reports that over the past 24 hours he has become increasingly rigid, agitated, and febrile. During the examination, the therapist notes extreme hypertonicity throughout his lower extremities.

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

  1. Baclofen overdose due to a pump malfunction delivering an excessive dose.
  2. Acute baclofen withdrawal due to a catheter or pump failure. (correct answer)
  3. Serotonin syndrome from an interaction with another medication.
  4. An expected fluctuation in spasticity that should be managed with prolonged stretching.
Explanation: This clinical picture—a rapid and severe increase in spasticity, fever, and altered mental status—is the classic presentation of acute intrathecal baclofen withdrawal. This is a life-threatening medical emergency often caused by pump failure, catheter blockage, or low reservoir volume. (A) is incorrect because baclofen overdose would present with CNS depression, including drowsiness, respiratory depression, and flaccidity or hypotonia, not hypertonicity. (C) is less likely as it typically requires a combination of serotonergic agents and presents with a different symptom cluster. (D) is incorrect because this is a rapid, severe change accompanied by systemic symptoms, indicating a medical emergency, not a typical fluctuation.

Question 14

A 55-year-old female was recently prescribed gabapentin for post-herpetic neuralgia affecting her right torso. She is in physical therapy for associated trunk stiffness and pain. After two weeks of treatment, she reports her pain has decreased from 8/10 to 4/10, but she now feels unsteady on her feet and has fallen once at home. Examination reveals mild ataxia during tandem walking.

What is the physical therapist's BEST course of action?

  1. Advise the patient to stop taking the gabapentin immediately due to the adverse effects.
  2. Attribute the unsteadiness to deconditioning from her pain and progress her strengthening exercises.
  3. Hold all therapy and refer the patient back to her physician for a full neurological workup.
  4. Incorporate specific balance and fall prevention exercises into the plan of care and communicate the findings to the physician. (correct answer)
Explanation: Ataxia, dizziness, and somnolence are very common, dose-dependent side effects of gabapentin, especially when treatment is initiated. These side effects significantly increase fall risk. The most appropriate action is to modify the plan of care to address this new impairment by adding balance and safety training. It is also essential to communicate these findings to the physician, who may consider adjusting the dose. (A) is inappropriate, as advising a patient to stop a prescribed medication is outside the PT scope of practice. (B) is incorrect because it ignores the clear temporal link between the new medication and the onset of ataxia. (C) is an overreaction; these are known side effects and can be managed by the PT while communicating with the physician.

Question 15

A 67-year-old male is being discharged from the hospital 3 days after an unprovoked DVT in his left lower extremity. He was started on intravenous heparin and is now being bridged to oral warfarin. His INR is 1.7. The physical therapist is providing discharge instructions regarding mobility.

What is the MOST critical education point for the physical therapist to emphasize?

  1. Performing aggressive ankle pumps and calf stretches for at least 10 minutes every hour to prevent DVT recurrence.
  2. The importance of strict bed rest until his INR is in the therapeutic range of 2.0-3.0 to prevent dislodging the clot.
  3. Implementing rigorous fall prevention strategies, as his risk of serious bleeding from minor trauma is currently very high. (correct answer)
  4. The need to maintain a consistent intake of foods high in vitamin K to ensure the warfarin works effectively.
Explanation: During the bridging period from heparin to warfarin, the patient is fully anticoagulated and at a high risk of bleeding. The warfarin dose is being titrated, and the INR is not yet stable. In this state, even a minor fall or trauma can cause a major hemorrhage. Therefore, the most critical priority from a physical therapy perspective is fall prevention. (A) is incorrect; while mobility is good, "aggressive" exercise is not indicated due to bleeding risk. (B) is incorrect; early mobilization is the standard of care for DVT once anticoagulation is initiated. (D) is important dietary advice but is secondary to the immediate physical safety concern of bleeding due to falls, which is the PT's primary domain.

Question 16

A 22-year-old college athlete with exercise-induced asthma uses an albuterol inhaler 15 minutes before every practice. After a particularly strenuous session, the physical therapist, who is providing sideline coverage, observes the athlete has a noticeable tremor in his hands and seems unusually nervous and jittery. The athlete denies any wheezing or shortness of breath.

Which of the following BEST explains the athlete's signs and symptoms?

  1. The patient is experiencing an acute asthma exacerbation that was not prevented by the albuterol.
  2. These are signs of exercise-induced hypoglycemia due to glycogen depletion during the strenuous practice.
  3. This is a paradoxical bronchospasm, a rare but serious adverse reaction to the albuterol inhaler.
  4. These are known systemic sympathomimetic effects of albuterol, including tremor and nervousness. (correct answer)
Explanation: Albuterol is a short-acting beta-2 agonist. While it primarily targets receptors in the lungs, some systemic absorption occurs, which can stimulate beta-adrenergic receptors elsewhere in the body. This can lead to common sympathomimetic side effects such as tachycardia, palpitations, nervousness, and skeletal muscle tremor. Since the athlete has no respiratory distress, these symptoms are best explained as known side effects of the medication. (A) is unlikely as he has no respiratory symptoms. (B) is possible after strenuous exercise, but the specific combination of tremor and nervousness is classic for albuterol. (C) is a rare event that would present with acute wheezing and respiratory distress, which the athlete denies.

Question 17

A 60-year-old patient with a long-standing history of schizophrenia is referred to physical therapy for balance deficits and frequent falls. The patient is taking haloperidol. The therapist's examination reveals a stooped posture, shuffling gait with reduced step length, bradykinesia, and a pill-rolling tremor in the right hand at rest.

The physical therapist should recognize these motor impairments as MOST consistent with which of the following medication-related conditions?

  1. Tardive dyskinesia
  2. Drug-induced pseudoparkinsonism (correct answer)
  3. Akathisia
  4. Neuroleptic malignant syndrome
Explanation: The patient's clinical presentation—shuffling gait, stooped posture, bradykinesia, and resting tremor—is a classic constellation of signs for parkinsonism. Because the patient is taking haloperidol, a first-generation (typical) antipsychotic that is a potent dopamine (D2) receptor antagonist, this is most likely drug-induced pseudoparkinsonism, a type of extrapyramidal symptom (EPS). (A) Tardive dyskinesia is characterized by involuntary, repetitive, choreoathetoid movements (e.g., lip-smacking, writhing). (C) Akathisia is a state of motor restlessness, an inability to sit still. (D) Neuroleptic malignant syndrome is a rare but life-threatening emergency characterized by fever, severe rigidity, autonomic instability, and altered mental status.

Question 18

A 79-year-old female is referred to home health physical therapy after a fall. Her medication list includes lorazepam for anxiety and hydrocodone/acetaminophen for chronic knee pain. The therapist notes she is very drowsy, has slurred speech, and her gait is markedly ataxic. The patient states she is taking both medications as prescribed.

The physical therapist's primary concern and subsequent plan should be based on the understanding of what pharmacological principle?

  1. First-pass metabolism has likely reduced the efficacy of the hydrocodone, requiring a higher dose for pain control.
  2. The patient has likely developed a tolerance to lorazepam, leading to withdrawal symptoms that mimic intoxication.
  3. There is a synergistic CNS depressant effect between benzodiazepines and opioids, creating a high risk for falls and respiratory depression. (correct answer)
  4. Acetaminophen toxicity is the most likely cause of her symptoms, requiring immediate referral for liver function tests.
Explanation: The concurrent use of benzodiazepines (lorazepam) and opioids (hydrocodone) causes a powerful synergistic, not just additive, depression of the central nervous system. This combination significantly increases the risk of profound sedation, ataxia, falls, and life-threatening respiratory depression. This interaction carries an FDA black box warning. The patient's presentation is a classic example of this dangerous synergy. The PT's plan must be dominated by safety concerns and communication with the physician. (A) and (B) are incorrect interpretations of pharmacology. (D) is incorrect because acetaminophen toxicity presents primarily with signs of liver failure, not the CNS depression seen here.

Question 19

A 48-year-old patient with adhesive capsulitis of the right shoulder receives an intra-articular corticosteroid injection from an orthopedist. The patient attends physical therapy the following day, reporting increased pain and stiffness at the injection site.

What is the MOST appropriate physical therapy intervention on this day?

  1. Focus on gentle, pain-free active-assistive range of motion and patient education regarding the potential for a post-injection flare. (correct answer)
  2. Initiate aggressive end-range stretching and joint mobilization to capitalize on the injection's long-term benefits.
  3. Apply deep thermal ultrasound over the anterior capsule followed by manual stretching to decrease pain and improve capsular extensibility.
  4. Begin a high-intensity strengthening program for the rotator cuff, as the corticosteroid will protect the joint from inflammation.
Explanation: When you encounter questions about corticosteroid injections in physical therapy, remember that these medications have both immediate and delayed effects that directly impact your treatment approach. A is correct because it recognizes a common phenomenon called "post-injection flare" - a temporary increase in pain and inflammation that can occur 24-48 hours after corticosteroid injection in up to 25% of patients. The appropriate response is conservative management with gentle, pain-free movements and patient education to reassure them this is normal and temporary. This approach respects the acute inflammatory response while maintaining some mobility. B is wrong because aggressive interventions immediately after injection ignore the post-injection flare and could exacerbate inflammation. While corticosteroids do provide long-term anti-inflammatory benefits, these don't peak until 3-7 days post-injection. C is wrong because deep heating and manual stretching are contraindicated during acute inflammation. Thermal ultrasound would increase metabolic activity and potentially worsen the inflammatory response, while manual stretching could further irritate already inflamed tissues. D is wrong because high-intensity strengthening during acute inflammation is inappropriate regardless of corticosteroid presence. The medication doesn't provide immediate "protection" - it gradually reduces inflammation over days to weeks. NPTE Strategy: When you see injection-related scenarios, always consider the timeline. Immediate post-injection care focuses on managing potential flare-ups conservatively, while the benefits of the injection are realized in subsequent visits. Don't be aggressive when inflammation is present, even if the long-term prognosis is good.

Question 20

A 50-year-old male with multiple sclerosis is being treated with dantrolene sodium for severe lower extremity spasticity. He attends his physical therapy session complaining of nausea and extreme fatigue for the past few days. The therapist observes that the sclera of his eyes has a distinct yellowish tint.

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

  1. Continue with a modified, low-intensity therapy session focused on energy conservation techniques.
  2. Attribute the symptoms to a multiple sclerosis exacerbation and document the change in status.
  3. Withhold therapy, inform the patient of the concern for a serious medication side effect, and ensure the patient contacts his physician immediately. (correct answer)
  4. Recommend the patient consume more fluids and rest, and reschedule his next appointment for one week.
Explanation: Dantrolene sodium carries a black box warning for potentially fatal hepatotoxicity. The combination of systemic symptoms (nausea, fatigue) and jaundice (yellowing of the sclera) are hallmark signs of liver damage. This constitutes a medical emergency. The therapist must stop the session and ensure the patient receives immediate medical attention from their physician or an emergency department. (A), (B), and (D) are all dangerously passive responses that fail to recognize the urgency of a red flag for a life-threatening adverse drug reaction.
