ATC Pharmacology 2 — Questions and Answers
Question 1: Which federal schedule classification applies to medications with accepted medical use but high potential for abuse, such as testosterone?
- Schedule I
- Schedule II
- Schedule III (Correct answer)
- Schedule IV
Correct answer: Schedule III
Testosterone and anabolic steroids are classified as Schedule III controlled substances under the Controlled Substances Act.
Question 2: An athlete is prescribed a corticosteroid injection for a shoulder injury. Which of the following is a primary concern with repeated corticosteroid injections?
- Increased bone density
- Tendon weakening and potential rupture (Correct answer)
- Enhanced wound healing
- Decreased pain sensitivity
Correct answer: Tendon weakening and potential rupture
Repeated corticosteroid injections can weaken collagen structure in tendons and surrounding tissues, increasing rupture risk.
Question 3: Which medication class is most commonly associated with exercise-induced bronchospasm (EIB) management in athletes?
- Beta-2 adrenergic agonists (Correct answer)
- Anticholinergics
- Leukotriene inhibitors
- Mast cell stabilizers
Correct answer: Beta-2 adrenergic agonists
Short-acting beta-2 agonists such as albuterol are the first-line treatment for EIB, providing rapid bronchodilation.
Question 4: A runner takes aspirin daily for cardiovascular prophylaxis. Which bleeding-related concern should an athletic trainer consider during wound care?
- Increased platelet aggregation
- Prolonged bleeding time (Correct answer)
- Accelerated clot formation
- Decreased fibrinolysis
Correct answer: Prolonged bleeding time
Aspirin irreversibly inhibits platelet cyclooxygenase, prolonging bleeding time and slowing hemostasis.
Question 5: Which of the following describes the concept of bioavailability in pharmacology?
- The speed at which a drug is metabolized by the liver
- The fraction of an administered drug that reaches systemic circulation unchanged (Correct answer)
- The total volume in which a drug is distributed in the body
- The rate at which a drug is excreted by the kidneys
Correct 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.
Question 6: An athlete using diuretics for weight cutting is at greatest risk for which electrolyte imbalance?
- Hypernatremia
- Hyperkalemia
- Hypokalemia (Correct answer)
- Hypercalcemia
Correct answer: Hypokalemia
Loop and thiazide diuretics increase urinary potassium excretion, commonly leading to hypokalemia.
Question 7: Which route of drug administration provides the fastest onset of action in an emergency situation?
- Sublingual
- Intramuscular
- Intravenous (Correct answer)
- Subcutaneous
Correct answer: Intravenous
Intravenous administration delivers a drug directly into the bloodstream, providing the most rapid onset of any route.
