Correct Answer: D

Rationale: The correct answer is to direct the nurse to continue the surgical hand scrub for a 5-minute duration. Surgical hand scrubs should last for 5 to 10 minutes, ensuring thorough cleaning and disinfection. Choice A is incorrect because the nurse should be guided to complete the scrub properly rather than having someone else do it. Choice B is incorrect as it does not address the duration of the hand scrub. Choice C is incorrect as it suggests a 3-minute hand scrub is sufficient, which is inadequate for proper preparation before surgery.

Correct Answer: A

Rationale: The correct answer is A. A 3-pound weight gain in two days indicates fluid retention and worsening heart failure, which requires immediate assessment. This could be a sign of decompensation in the client's condition, necessitating prompt evaluation and intervention. Choices B, C, and D do not present an immediate threat to the client's health and can be addressed after assessing the client with congestive heart failure.

Correct Answer: D

Rationale: The correct answer is D. A client who had an abdominal-perineal resection 2 days ago with no drainage on the dressing but is presenting with fever and chills requires immediate attention. This presentation raises concerns for peritonitis, a serious complication that necessitates prompt assessment and intervention to prevent further complications. Choices A, B, and C do not indicate an immediate risk for a life-threatening condition like peritonitis, making them lower priority compared to choice D.

Correct Answer: B

Rationale: The correct instruction for the nurse to include in the medication teaching plan for a client receiving enalapril, an ACE inhibitor, is to 'Report increased bruising or bleeding.' ACE inhibitors can cause thrombocytopenia, which can lead to an increased risk of bruising and bleeding. Monitoring and reporting these symptoms promptly are essential to prevent complications. Choices A, C, and D are incorrect because increasing potassium-rich foods, stopping medication if a cough develops, and limiting intake of leafy green vegetables are not directly related to the common side effects or actions of ACE inhibitors.

Correct Answer: C

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. In DKA, there is a lack of insulin leading to hyperglycemia and ketosis. Insulin administration helps to reduce blood glucose levels and correct metabolic acidosis, which are crucial in treating DKA. Administering intravenous fluids helps with dehydration, monitoring urine output is important to assess renal function, but the priority is addressing the underlying cause of DKA by administering insulin. Administering 50% dextrose IV push is incorrect as it would further elevate blood glucose levels, which is contraindicated in DKA.
