Pharmacology & Medication Effects on Exercise Flashcards

Which class of medications is most likely to blunt the heart rate response during exercise, making heart rate an unreliable measure of exercise intensity?

Answer: Beta-blockers

Beta-blockers block adrenergic receptors, reducing heart rate at rest and during exercise, making heart-rate-based intensity monitoring unreliable.

A client taking loop diuretics (e.g., furosemide) should be monitored during exercise primarily for which concern?

Answer: Dehydration and electrolyte imbalances

Loop diuretics increase urinary output, leading to dehydration and electrolyte losses (especially hypokalemia), which increases exercise risk.

Which side effect of statin medications is most clinically relevant when a MES designs a resistance training program?

Answer: Myopathy and muscle pain

Statins can cause myopathy (muscle weakness and pain) and rarely rhabdomyolysis, requiring careful monitoring during resistance training.

When working with a client who takes insulin for Type 1 diabetes, which exercise-related concern requires the most careful monitoring?

Answer: Exercise-induced hypoglycemia

Both insulin and muscle contractions promote glucose uptake, and together they can cause blood glucose to drop dangerously low during exercise.

A client is on beta-blockers with a resting heart rate of 52 bpm. What is the most appropriate method for monitoring exercise intensity?

Answer: Rating of Perceived Exertion (RPE)

Because beta-blockers blunt the heart rate response, RPE (Borg scale) is the most reliable method for monitoring exercise intensity in these clients.

ACE inhibitors are commonly prescribed for hypertension. Which exercise-related side effect is most important for a MES professional to recognize?

Answer: They may cause a persistent dry cough affecting breathing during exercise

ACE inhibitors commonly cause a persistent dry cough as a side effect, which may limit breathing comfort and should be documented by the MES.

Calcium channel blockers affect exercise programming primarily by:

Answer: Reducing myocardial oxygen demand and potentially lowering blood pressure during exercise

Calcium channel blockers reduce myocardial contractility and promote vasodilation, potentially causing hypotension during or after exercise that requires monitoring.
