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) This option is incorrect. Maternal age is a non-modifiable risk factor. However, it is important to educate parents about other factors they can control during pregnancy.
B) This option is incorrect. Family history of heart diseases is a non-modifiable risk factor since it relates to the genetic predisposition for certain conditions.
C) Correct answer. Exposure to environmental toxins can be a modifiable risk factor if expectant parents take appropriate measures to avoid exposure to harmful substances during pregnancy. This may include avoiding certain chemicals, pollutants, and teratogenic agents.
D) This option is incorrect. Genetic inheritance is a non-modifiable risk factor for congenital heart diseases, as it relates to the transmission of genes from parents to their children.
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.
