Correct Answer: D

Rationale: The priority nursing intervention in this situation is to ask the client if she has experienced any recent changes in vaginal discharge. Changes in vaginal discharge can indicate preterm labor, making it crucial to assess promptly. This information will help determine if the client needs immediate medical attention and appropriate interventions to prevent preterm birth and ensure the well-being of the mother and the baby. Option A is not the priority as back pain alone does not warrant immediate ambulance transport. Option B is less relevant in this context as the focus should be on immediate concerns related to pregnancy. Option C is not the priority as addressing back pain should come after ruling out urgent pregnancy-related issues.

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: To confirm respiratory distress syndrome (RDS) in a newborn, the nurse should assess diaphragmatic breathing. In RDS, the baby may have difficulty breathing due to immature lungs, leading to shallow, rapid breathing movements. Assessing diaphragmatic breathing directly evaluates the respiratory effort and can help identify the presence of RDS. Choice B, assessing heart sounds, is not specific to diagnosing RDS but could be relevant for other conditions. Choice C, monitoring blood oxygen levels, is important but alone may not confirm RDS. Choice D, checking for signs of infection, is not a direct indicator of RDS but rather suggests a different issue.

Correct Answer: D

Rationale: The best time for the couple to attend childbirth preparation classes is around 30 weeks gestation, which is during the third trimester. Attending classes at this time allows the couple to learn essential information and skills as labor and delivery are approaching, maximizing the benefit of the classes. Option A is too early in the second trimester, and the couple might forget important details by the time labor approaches. Option B is also early in the second trimester, and attending later allows for better preparation. Option C is still in the second trimester, and waiting until the third trimester provides more practical knowledge closer to delivery.

Correct Answer: B

Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.
