A nurse is preparing to administer a dose of prostaglandin E1 to an infant with a congenital heart disease. What is the primary therapeutic effect of this medication?
Improve oxygenation by increasing hemoglobin levels.
Reduce pulmonary blood flow and pressure.
Close a patent ductus arteriosus (PDA).
Promote the growth of cardiac muscle tissue.
The Correct Answer is C
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.
