Correct Answer is B
Explanation
Choice A rationale:
Terbutaline is a medication used to inhibit uterine contractions and is not directly related to managing coarctation of the aorta.
Choice B rationale:
Coarctation of the aorta is a congenital heart defect characterized by narrowing of the aorta, which can lead to increased pressure and decreased blood flow to the lower part of the body. During labor, epidural anesthesia is often recommended for clients with coarctation of the aorta to reduce stress and pain, as well as to maintain stable blood pressure.
Choice C rationale:
Placing a client with coarctation of the aorta in a supine position during labor can worsen the obstruction of blood flow and is contraindicated. Left lateral positioning or other positions that enhance venous return are preferred.
Choice D rationale:
There is no established increased risk of preeclampsia in clients with coarctation of the aorta.
Correct Answer is A

Melanoma has multiple growth phases, including radial and vertical growth.
