Correct Answer: C

Rationale: The correct action for the nurse to take is to keep the infant's head covered with a cap. This helps regulate the newborn's body temperature during phototherapy. Option A, feeding the infant glucose water every 2 hours, is incorrect because it is not a standard intervention for newborns receiving phototherapy. Option B, ensuring the newborn wears a diaper, may be necessary for hygiene but is not directly related to phototherapy. Option D, applying lotion to the newborn every 4 hours, is unnecessary and not indicated for managing jaundice or phototherapy.

Correct Answer: D

Rationale: The correct answer is D. Captopril is known to cause a persistent, dry cough as a common side effect. Instructing the client about this potential side effect is crucial for their awareness. Choices A and B are incorrect because captopril is usually taken on an empty stomach. Choice C is incorrect because captopril can lead to hyperkalemia, so potassium supplements may be necessary in some cases.

Correct Answer: B

Rationale: The correct answer is B: JVD. Jugular venous distention (JVD) is a common finding in right-sided heart failure due to fluid overload. This occurs because the right side of the heart is unable to effectively pump blood, leading to congestion and increased venous pressure, which is manifested as JVD. Choices A, C, and D are incorrect. Peripheral edema (choice A) is more commonly associated with left-sided heart failure. Crackles in the lungs (choice C) are indicative of pulmonary edema, often seen in left-sided heart failure. Hypotension (choice D) is not typically seen in right-sided heart failure, as it is more commonly associated with conditions like shock or severe dehydration.

Correct Answer: C

Rationale: The correct answer is C. A temperature of 38.6°C (101.5°F) is above the normal range and indicates a fever, which is a concerning finding postoperatively. Fever can be a sign of infection, so the nurse should report this finding to the provider for further evaluation and intervention. Choices A, B, and D are within expected parameters for a client who is 24 hours postoperative following abdominal surgery and do not require immediate reporting. A heart rate of 90/min, serosanguineous drainage in the surgical drain, and a urinary output of 60 mL/hr are all common postoperative findings that do not raise immediate concerns.

Correct Answer: B

Rationale: The correct answer is B because informing the child that they will feel discomfort during catheter insertion is crucial to prepare them for the procedure. Choice A is incorrect as children should not handle medical supplies. Choice C is inappropriate as using a restraint can cause anxiety and fear in the child. Choice D is not necessary as having parents present can provide comfort and support to the child during the procedure.
