A newborn infant in the nursery has developed vomiting, poor feeding, lethargy, and respiratory distress, and has been diagnosed with necrotizing enterocolitis. Which of the following nursing interventions is most appropriate for this infant?

Correct Answer: C

Rationale: Necrotizing enterocolitis (NEC) is a serious condition characterized by ischemic bowel, leading to gastrointestinal symptoms, lethargy, poor feeding, and respiratory distress. In the management of NEC, it is crucial to stop oral feedings, insert a nasogastric tube for decompression, and administer antibiotics as prescribed by the physician. Therefore, the most appropriate nursing intervention for an infant with NEC is to administer antibiotics as ordered. Choice A, feeding the infant sterile water, is incorrect because oral feedings should be stopped in NEC. Choice B, positioning the infant on his back, is not directly related to the treatment of NEC. Choice D, allowing the infant to breastfeed, is contraindicated in NEC as oral feedings should be ceased to prevent further complications.

Correct Answer: C

Rationale: To prepare a patient with ascites for paracentesis, the nurse should ask the patient to empty the bladder. This is important to decrease the risk of bladder perforation during the procedure. The patient should be positioned in Fowler's position to facilitate the procedure, not lie flat in bed, which can compromise breathing. Placing the patient on NPO status is unnecessary as sedation is not typically required for paracentesis. Positioning the patient on the right side is not a standard preparatory measure for paracentesis.

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: C

Rationale: The correct answer is C: Amylase. In acute pancreatitis, amylase levels are typically elevated. Monitoring amylase levels helps assess the effectiveness of therapy in managing the condition. Elevated amylase is a key indicator of pancreatic inflammation. Calcium (Choice A) levels may be affected in pancreatitis, but they are not the primary indicator for evaluating therapy effectiveness. Bilirubin (Choice B) and Potassium (Choice D) levels may also be altered in pancreatitis, but they are not specific markers for monitoring therapy response in acute pancreatitis.

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.
