Correct Answer: B

Rationale: The correct answer is B because the client needs a second varicella vaccination at the postpartum visit to ensure immunity. Option A is incorrect as it implies a future need for a second vaccination without a clear action plan. Option C is incorrect as the varicella vaccine is primarily for the client's protection, not others. Option D is not the appropriate action as waiting to be tested for immunity delays the necessary second vaccination.

Correct Answer: C

Rationale: Tilting the bottle to prevent air from entering as the baby sucks can lead to the baby swallowing air, causing discomfort and potential issues like colic or gas. The correct way to bottle-feed a newborn is by ensuring that the nipple is always filled with milk to avoid air intake, which can lead to problems. Keeping the baby's head elevated while feeding helps prevent choking, allowing the baby to burp several times during each feeding helps release swallowed air, and soft, formed yellow stools indicate a healthy digestion process in newborns.

Correct Answer: D

Rationale: Measuring leg circumferences is crucial in monitoring for changes that may indicate worsening of thrombophlebitis, such as increased swelling or redness. This assessment helps in early detection of complications and timely intervention, reducing the risk of further health problems for the client. Applying cold compresses may worsen the condition by causing vasoconstriction. Massaging the affected extremity can dislodge a clot and lead to embolism. Allowing the client to ambulate may increase the risk of clot migration.

Correct Answer: D

Rationale: A displaced and boggy fundus in a postpartum client typically indicates a full bladder, which can impede uterine contractions and increase the risk of postpartum hemorrhage. Assisting the client to the bathroom to void helps ensure the bladder is empty, aiding the fundus to contract and reducing the risk of complications. Encouraging Kegel exercises, changing positions, or assessing pain would not directly address the issue of the boggy fundus caused by a full bladder.

Correct Answer: B

Rationale: The priority action for the nurse in this situation is to position the client with one hip elevated. This position can help improve blood flow to the placenta and stabilize blood pressure, which is crucial for both the client and the fetus during labor. It can also help optimize fetal oxygenation by improving circulation. Notifying the provider of the findings may be necessary, but ensuring proper positioning of the client takes precedence to address the immediate physiological needs. Asking the client about pain medication or having the client void are important interventions but are not the priority in this scenario where the client is experiencing painful contractions and has low blood pressure.
