A nurse is caring for an infant with a congenital heart disease who requires prostaglandin E1 therapy. What is the primary purpose of administering prostaglandin E1?
To improve cardiac contractility.
To reduce systemic blood pressure.
To promote ductus arteriosus closure.
To decrease heart rate.
The Correct Answer is C
A) Incorrect. Prostaglandin E1 does not primarily aim to improve cardiac contractility. It is used for a different purpose in the management of congenital heart diseases.
B) Incorrect. Prostaglandin E1 is not used to reduce systemic blood pressure. In fact, it may have the opposite effect, causing vasodilation and potentially lowering blood pressure.
C) The answer is C. Prostaglandin E1 is used to promote and maintain the patency of the ductus arteriosus, especially in critical congenital heart defects. This ensures adequate blood flow to systemic circulation until corrective surgery can be performed.
D) Incorrect. Prostaglandin E1 does not decrease heart rate. It primarily affects the patency of the ductus arteriosus.

Correct Answer is A
Explanation
A) The answer is A. Weight gain of 1 pound in a week can indicate fluid retention, which may be a sign of digoxin toxicity. The nurse should instruct the client to report this symptom immediately to prevent further complications.
B) Incorrect. A heart rate below 100 beats per minute is within the normal range for most clients. A lower heart rate is often expected in clients taking digoxin, and it does not require immediate reporting unless accompanied by other concerning symptoms.
