A client with a congenital heart disease is experiencing cyanosis and clubbing of the fingers. The nurse should recognize these symptoms as signs of:
Left-sided heart failure.
Right-sided heart failure.
Pulmonary hypertension.
Peripheral vascular disease.
The Correct Answer is C
A) Incorrect. Left-sided heart failure typically presents with symptoms such as pulmonary congestion, shortness of breath, and crackles in the lungs, rather than cyanosis and clubbing.
B) Incorrect. Right-sided heart failure can cause peripheral edema and jugular vein distention, but it does not usually lead to cyanosis and clubbing.
C) The answer is C. Cyanosis and clubbing of the fingers are signs of chronic hypoxia, which can occur in pulmonary hypertension. This condition increases pulmonary vascular resistance and impairs oxygenation, leading to these characteristic symptoms.
D) Incorrect. Peripheral vascular disease primarily affects the arteries and veins in the extremities and is not directly related to cyanosis and clubbing of the fingers.

Correct Answer is C
Explanation
A) Incorrect. Prostaglandin E1 does not directly increase hemoglobin levels or oxygenation in the blood.
B) Incorrect. Prostaglandin E1 helps maintain the patency of the ductus arteriosus to ensure adequate blood flow to systemic circulation, especially in certain congenital heart diseases. It does not reduce pulmonary blood flow and pressure.
C) The answer is C. Prostaglandin E1 is used to keep the ductus arteriosus open, allowing blood to flow from the pulmonary artery to the aorta. In certain congenital heart diseases, such as critical congenital heart defects, this is necessary to ensure adequate blood circulation.
D) Incorrect. Prostaglandin E1 does not promote the growth of cardiac muscle tissue. Its primary therapeutic effect is related to the patency of the ductus arteriosus.
Correct Answer is D
Explanation
A) This option is incorrect. Frequent sweating during feedings is not a normal response to the increased workload of the baby's heart. It can indicate an underlying issue related to heart function.
B) This option is incorrect. While gastrointestinal discomfort may cause sweating during feedings, it is not the most likely explanation, especially in the context of congenital heart diseases.
C) This option is incorrect. Inability to regulate body temperature is not a common reason for sweating during feedings in infants with congenital heart diseases.
D) Correct answer. Excessive sweating during feedings can be a sign of increased cardiac effort and inadequate oxygen supply in some congenital heart diseases. This symptom may be present in babies with cyanotic heart defects, where oxygen-rich blood is not adequately circulated to the body, leading to compensatory mechanisms like sweating to maintain oxygen balance.
