Correct Answer: A

Rationale: Administering analgesics is the most effective intervention for a patient experiencing acute pain as it directly targets the pain receptors and provides relief. Repositioning the patient may help in some cases, but it is not the primary intervention for managing acute pain. Non-pharmacological interventions can be beneficial as adjuncts to pain management but might not provide immediate relief. Administering IV fluids is not a standard intervention for acute pain unless dehydration is contributing to the pain.

Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is crucial in managing patients with chronic heart failure as it helps assess fluid balance. Monitoring daily weight allows healthcare providers to detect any sudden weight gain, which could indicate fluid retention and worsening heart failure. This intervention helps in adjusting treatment plans promptly. Providing fluid restriction (Choice B) can be a part of managing heart failure but is not the primary intervention mentioned in the question. Administering diuretics (Choice C) is a treatment modality for heart failure but does not encompass the comprehensive approach to patient management. Monitoring intake and output (Choice D) is important but does not specifically address the direct assessment of fluid status as daily weight monitoring does.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Tachycardia can indicate a hemolytic transfusion reaction, a severe and life-threatening complication of blood transfusion. The nurse should report tachycardia immediately to prevent further complications. Low back pain, flushed skin, and headache are also important to monitor during a blood transfusion, but they are not as indicative of a severe transfusion reaction as tachycardia.

Correct Answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

Correct Answer: D

Rationale: The correct intervention for a client with a stage 3 pressure injury is to apply a moisture barrier ointment. This helps protect the skin, maintain moisture balance, and promote healing. Choice A is incorrect because povidone-iodine solution can be too harsh for wound care. Choice B is incorrect as hydrogen peroxide can be cytotoxic to healing tissue. Choice C is important for preventing pressure injuries but is not a direct intervention for a stage 3 wound.
