Correct Answer: C

Rationale: The correct answer is Hypokalemia (Choice C). Loop diuretics can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is a common concern with loop diuretic therapy and necessitates regular monitoring. Hyperkalemia (Choice A) is not typically associated with loop diuretics but with conditions like renal failure. Hyponatremia (Choice B) is more common with thiazide diuretics. Hypercalcemia (Choice D) is not a typical concern with loop diuretic use.

Correct Answer: C

Rationale: The correct answer is C: 'Use a new catheter each time you perform self-catheterization.' It is essential to use a new, sterile catheter each time to prevent infection during the procedure. Choice A is incorrect because cleaning the catheter with alcohol may not be sufficient to prevent infection. Choice B is incorrect because self-catheterization is typically done in a clean, private area, not necessarily on the toilet. Choice D is incorrect because lubricating the catheter tip with petroleum jelly is a common practice but not as crucial as using a new catheter each time to prevent infection.

Correct Answer: B

Rationale: The correct answer is B. Weighing oneself daily is crucial in monitoring fluid retention, a key aspect in managing heart failure. This helps in detecting early signs of fluid buildup, prompting timely interventions. Choice A is incorrect as the recommended sodium intake for heart failure clients is usually lower, around 2-3 grams daily. Choice C is incorrect because excessive water intake can worsen fluid retention in heart failure. Choice D is incorrect as clients with heart failure should consult healthcare providers before significantly altering their physical activity levels.

Correct Answer: A

Rationale: Respecting the patient's beliefs is crucial in providing patient-centered care. Attempting to persuade the patient may violate their autonomy and decision-making capacity, leading to a breakdown in trust. Providing education on treatment benefits may be appropriate in other situations but is not the best approach when a patient refuses treatment based on religious reasons. Documenting the refusal and notifying the provider are important steps to ensure proper continuity of care, but the primary response should be to respect the patient's beliefs to maintain a trusting relationship and uphold ethical standards.

Correct Answer: B

Rationale: Assisting the client to splint the incision with a pillow while coughing is the correct action in this scenario. This intervention helps reduce pain and prevent wound dehiscence, which is the partial or complete separation of the layers of a surgical wound. Monitoring urinary output is important but not the priority at this immediate postoperative stage. Providing a clear liquid diet may be indicated later but is not the most immediate concern. Encouraging ambulation is beneficial for preventing complications like deep vein thrombosis, but splinting the incision is more crucial at this early postoperative period.
