An athlete is prescribed a corticosteroid injection for a shoulder injury. Which of the following is a primary concern with repeated corticosteroid injections?

Answer: Tendon weakening and potential rupture

Repeated corticosteroid injections can weaken collagen structure in tendons and surrounding tissues, increasing rupture risk.

Which medication class is most commonly associated with exercise-induced bronchospasm (EIB) management in athletes?

A runner takes aspirin daily for cardiovascular prophylaxis. Which bleeding-related concern should an athletic trainer consider during wound care?

Answer: Prolonged bleeding time

Which of the following describes the concept of bioavailability in pharmacology?

Answer: The fraction of an administered drug that reaches systemic circulation unchanged

Bioavailability refers to the proportion of a drug dose that enters the systemic circulation in an active form.

An athlete using diuretics for weight cutting is at greatest risk for which electrolyte imbalance?

Answer: Hypokalemia

Loop and thiazide diuretics increase urinary potassium excretion, commonly leading to hypokalemia.

Which route of drug administration provides the fastest onset of action in an emergency situation?
