Correct Answer: C

Rationale: The correct answer is the patient's temperature of 100.8°F (38.2°C). In a patient who received a liver transplant 1 week ago, a fever is a significant finding that should be promptly communicated to the health care provider. Post-transplant patients are at high risk of infections, and fever can often be the initial indicator of an underlying infectious process. The other findings listed in choices A, B, and D are important and should be addressed, but they do not take precedence over a potential infection post-liver transplant. Dry palpebral and oral mucosa may indicate dehydration, crackles at bilateral lung bases may suggest fluid overload or infection, and no bowel movement for 4 days could indicate a bowel obstruction or ileus. However, in the context of a recent liver transplant, an elevated temperature is the most concerning and requires immediate attention to rule out infection.

Correct Answer: D

Rationale: The correct answer is muscle twitching and finger numbness. These symptoms indicate hypocalcemia, which can lead to tetany if not promptly addressed with calcium gluconate administration. Nausea and vomiting, hypotonic bowel sounds, and abdominal tenderness and guarding are important findings in acute pancreatitis but do not require the same urgent intervention as hypocalcemia to prevent potential severe complications.

Correct Answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

Correct Answer: C

Rationale: In this scenario, the nurse observed carpal spasms in the patient's right hand, indicating a positive Trousseau's sign, which is associated with hypocalcemia. Patients with acute pancreatitis are at risk for hypocalcemia, hence the nurse should promptly check the calcium level in the chart to assess the patient's condition. Notifying the healthcare provider comes after confirming the calcium level. There is no indication to ask about arm pain or to retake the blood pressure, as the primary concern is addressing the potential hypocalcemia.

Correct Answer: B

Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.
