Correct Answer: A

Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.

Correct Answer: C

Rationale: The best approach for the nurse to suggest is to make the woman responsible for the consequences of her drinking behaviors. By holding her accountable, she is more likely to recognize the impact of her actions and potentially initiate change. Destroying hidden alcohol supplies (Choice A) might lead to conflict and further secretive behavior. Simply communicating the disruptions caused by her drinking (Choice B) may not effectively address the issue. Including her in family activities regardless of her drinking status (Choice D) could enable the behavior and not address the underlying problem.

Correct Answer: A

Rationale: Administering the prescribed analgesic when requested reflects the nurse's value of client autonomy over veracity. This choice respects the client's right to manage their pain as they see fit. Enrolling the client in a substance abuse program (Choice B) assumes substance abuse without evidence and infringes on the client's autonomy. Providing a placebo (Choice C) violates the principle of beneficence and autonomy by deceiving the client. Documenting the frequency of medication requests (Choice D) is important for assessment but does not directly address the client's autonomy in managing their pain.

Correct Answer: D

Rationale: In the oliguric phase of acute renal failure (ARF), the goal is to prevent fluid overload. Since the client has a low urine output of 400 ml in 24 hours, limiting oral intake to 900 to 1,000 ml is appropriate. Encouraging unrestricted oral fluids (Choice A) can exacerbate fluid overload. Decreasing oral intake to 200 ml (Choice B) would be too restrictive and may lead to dehydration. Allowing the client to have exactly 400 ml oral intake (Choice C) would not account for other sources of fluid intake and output, potentially resulting in fluid imbalance.

Correct Answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
