Infant with transposition of the great vessels receiving prostaglandin E
Question 1 of 5
The nurse administered prostaglandin E to an infant with transposition of the great vessels. The nurse expects which effect to occur from the medication?
Correct Answer: B
Rationale: The correct answer is B: Ductus arteriosus remains open. Prostaglandin E helps keep the ductus arteriosus open in infants with transposition of the great vessels, improving mixing of oxygenated and deoxygenated blood.
Choice A is incorrect because the ductus venosus is a fetal vessel that closes shortly after birth.
Choice C is incorrect as deoxygenated blood mixing is necessary in this condition.
Choice D is incorrect because closing the ductus arteriosus would worsen oxygenation in this case.
