Pharmacological Impact on PT - National Physical Therapy Examination NPTE

1. Which medication class can cause muscle weakness and tendinopathy, affecting prognosis for strengthening programs?

   Corticosteroids (systemic). Prolonged use leads to proximal muscle atrophy and connective tissue fragility, delaying recovery in resistance training.

2. What is the key care-planning implication of NSAID use for a patient with hypertension or heart failure?

   NSAIDs can raise blood pressure and worsen fluid retention; monitor vitals and symptoms. These analgesics inhibit prostaglandins, exacerbating hypertension or edema, requiring vigilant monitoring in at-risk patients.

3. What is the primary PT safety concern when a patient is taking insulin or sulfonylureas during exercise sessions?

   Hypoglycemia risk during or after exercise. These agents lower blood glucose, potentially causing weakness, confusion, or seizures if exercise depletes energy stores.

4. Identify the medication class that increases bleeding risk and alters manual therapy and fall-injury precautions.

   Anticoagulants (for example, warfarin or DOACs). These agents impair clotting, heightening hematoma risk from trauma or aggressive interventions in physical therapy.

5. Identify the diabetes medication class that can cause hypoglycemia and is often timed with meals, affecting session timing.

   Sulfonylureas. These insulin secretagogues heighten low blood sugar risk, requiring session scheduling around meals for safety.

6. Identify the common adverse effect of opioid analgesics that directly increases fall risk during mobility training.

   Sedation and dizziness. Opioids depress the central nervous system, impairing balance and coordination essential for safe ambulation practice.

7. Which antiplatelet medication commonly used after stent placement increases bruising risk during exercise and transfers?

   Clopidogrel. This P2Y12 inhibitor prolongs bleeding time, elevating hematoma risk from minor impacts during functional training.

8. Which medication class used for Parkinson disease can cause dyskinesia or orthostatic hypotension affecting gait training?

   Levodopa (dopaminergic therapy). These drugs restore dopamine but may induce involuntary movements or blood pressure drops during movement therapy.

9. Identify the medication class that commonly causes dry mouth and blurred vision, increasing fall risk in older adults.

   Anticholinergics. These agents block muscarinic receptors, causing sensory impairments that reduce stability and increase injury risk.

10. Which diuretic type is most associated with hypokalemia that may present as weakness or arrhythmia risk?

    Loop diuretics. These potent diuretics promote potassium excretion, risking muscle weakness or cardiac rhythm disturbances during exertion.

11. Which respiratory medication may cause tachycardia and tremor that can confound cardiopulmonary response to exercise?

    Short-acting beta-2 agonists (for example, albuterol). These bronchodilators stimulate beta receptors, elevating heart rate and causing shakes that mimic exercise stress.

12. Which lab value is most relevant to monitor bleeding risk in a patient taking warfarin during PT care planning?

    INR. Elevated INR indicates excessive anticoagulation, guiding precautions against bleeding in manual or mobility interventions.

13. Which medication class increases fall risk by sedation and impaired coordination, impacting balance and gait training safety?

    Benzodiazepines. These anxiolytics cause central nervous system depression, reducing reaction time and stability during dynamic activities.

14. What is the key rehabilitation implication of long-term systemic corticosteroid use on connective tissue and bone?

    Increased risk of osteoporosis and tendon rupture; progress loading cautiously. Chronic exposure weakens bones and tendons, necessitating gradual progression to avoid fractures or ruptures in rehab.

15. Which medication class is most associated with statin-induced myopathy that may mimic exertional muscle pain?

    HMG-CoA reductase inhibitors (statins). These cholesterol-lowering drugs can induce rhabdomyolysis or myalgias, complicating differentiation from exercise soreness.

16. What electrolyte abnormality risk is most associated with thiazide diuretics relevant to muscle performance?

    Hypokalemia. Thiazides promote potassium loss, which can impair muscle contraction and strength, relevant for functional assessments.

17. Identify the medication class that can cause cough and angioedema, affecting breathing and airway safety during therapy.

    ACE inhibitors. These agents inhibit angiotensin conversion, potentially causing airway issues that compromise respiratory function in therapy.

18. Which antihypertensive class commonly causes orthostatic hypotension that can confound gait and balance testing?

    Alpha-1 blockers. These drugs cause vasodilation, leading to postural blood pressure drops that mimic or exacerbate balance issues.

19. Identify the medication class most associated with exercise intolerance and bradycardia due to blunted heart rate response.

    Beta-adrenergic blockers. These agents blunt sympathetic stimulation, limiting heart rate increase and potentially causing fatigue during activity.

20. What is the best monitoring method to prescribe aerobic intensity for a patient taking a beta blocker?

    Use RPE (Borg scale) and symptoms rather than target heart rate. Beta blockers suppress heart rate response, making perceived exertion a safer intensity guide than heart rate targets.

21. What is the single most important medication-related question to ask before initiating a new exercise program?

    Ask about recent medication changes (new drug, dose change, or missed doses). Recent changes can alter physiological responses, increasing risks like hypotension or arrhythmias during exercise initiation.
