The nurse is preparing to administer a dose of digoxin (Lanoxin) to a child in heart failure (HF). Which is a beneficial effect of administering digoxin (Lanoxin)?
- 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.

- A. Dermal erythropoiesis
- B. Thrombocytopenia
- C. Ecchymosis
- D. Vasculitis

Examples of cyanotic heart disease include:
- A. Ebstein's anomaly
- B. Pulmonary stenosis
- C. Coarctation of aorta
- D. Hypoplastic left heart syndrome
Correct Answer: D
Rationale: Hypoplastic left heart syndrome is a form of cyanotic heart disease. Ebstein's anomaly and pulmonary stenosis can also cause cyanosis, but coarctation of the aorta typically does not.
What should the nurse assess prior to administering digoxin? (Select all that apply.)
- A. Sclera
- B. Apical pulse rate
- C. Cough
- D. Liver function test
Correct Answer: B
Rationale: Because digoxin decreases the heart rate, the apical pulse should be assessed. If the HR is below 60 beats per minute, digoxin should not be administered.
A nurse assesses a client after administering a prescribed beta blocker. Which assessment should the nurse expect to find?
- A. Blood pressure increased from 98/42 mm Hg to 132/60 mm Hg
- B. The respiratory rate decreased from 25 breaths/min to 14 breaths/min
- C. Pulse decreased from 100 beats/min to 80 beats/min
- D. Oxygen saturation increased from 88% to 96%
Correct Answer: D
Rationale: Beta blockers reduce heart rate and blood pressure. A decrease in pulse rate from 100 beats/min to 80 beats/min is consistent with the expected pharmacological effect of a beta blocker.
