- A. It decreases edema.
- B. It decreases cardiac output.
- C. It increases heart size.
- D. It increases venous pressure.
Correct Answer: A
Rationale: Digoxin has a rapid onset and is useful for increasing cardiac output, decreasing venous pressure, and, as a result, decreasing edema. Cardiac output is increased by digoxin. Heart size and venous pressure are decreased by digoxin.

Obesity in childhood:
- A. Is usually associated with hypogonadism
- B. Is unlikely to lead to adult obesity
