Correct Answer: A

Rationale: The correct answer is A. RhoGAM is administered to Rh-negative individuals after exposure to Rh-positive blood to prevent the development of antibodies that could harm future Rh-positive babies during subsequent pregnancies. By refusing RhoGAM after the delivery of an Rh-positive infant, the mother risks developing these antibodies, which could lead to hemolytic disease in future pregnancies with Rh-positive babies. Therefore, it is crucial for the nurse to explain to the client that receiving RhoGAM prevents the formation of maternal antibodies against Rh-positive blood, safeguarding the health of future babies. Choices B, C, and D are incorrect. Choice B is incorrect because RhoGAM is necessary after exposure to Rh-positive blood, regardless of the Rh status of future pregnancies. Choice C is incorrect as it does not accurately convey the purpose of RhoGAM administration. Choice D is incorrect because RhoGAM is specifically given after exposure to Rh-positive blood, not when the baby is Rh-negative.

Correct Answer: D

Rationale: An elevated alpha-fetoprotein (AFP) level in a pregnant client can indicate potential congenital anomalies in the fetus. A follow-up sonogram is necessary to provide definitive results and further evaluate the fetus for any possible abnormalities. Therefore, it is essential for the nurse to explain to the client that scheduling a sonogram is the next appropriate step to assess the fetal well-being and address any concerns regarding the elevated AFP level. Choices A, B, and C are incorrect because a repeat AFP test alone, discussing surgical correction of defects, or assuming the results are false without further evaluation are not appropriate responses when dealing with a potentially serious issue like elevated AFP levels in pregnancy.

Correct Answer: A

Rationale: Cephalhematoma is the accumulation of blood between the periosteum and skull, often due to birth trauma, and typically resolves within weeks. It is a common finding in newborns and is not usually a cause for concern as it gradually resolves without specific treatment. Subarachnoid hematoma and subdural hematoma are different conditions that present with distinct characteristics and require different management strategies. Therefore, the correct answer is A. Subarachnoid hematoma is typically found in the subarachnoid space and requires immediate intervention, not just observation like cephalhematoma. Molding refers to the shaping of the fetal head during passage through the birth canal and is a temporary change, not a collection of blood like in cephalhematoma. Subdural hematoma is located beneath the dura mater and is associated with significant complications, unlike the self-limiting nature of cephalhematoma.

Correct Answer: A

Rationale: After childbirth, engorgement of the breasts can occur, leading to swelling and discomfort. Applying cold compresses helps reduce swelling and provides comfort for engorged breasts. This action can also help with pain relief and promote milk flow regulation. Instructing the client to run warm water on her breasts (Choice B) is incorrect as warm water can increase blood flow and exacerbate swelling. Wearing a loose-fitting bra (Choice C) may provide some comfort, but it does not address the swelling effectively. Expressing small amounts of milk (Choice D) may provide temporary relief but does not address the underlying issue of engorgement.

Correct Answer: B

Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.
