Correct Answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting clients with C. difficile is crucial to prevent the transmission of the infection. Options A, B, and C are incorrect because assigning the client to a room with a negative air-flow system, using alcohol-based hand sanitizer, and cleaning contaminated surfaces with a phenol solution are not specific measures for preventing the spread of C. difficile.

Correct Answer: B

Rationale: The most important teaching point for a client with diabetes being discharged is to administer insulin before meals as prescribed. This is crucial for managing blood sugar levels effectively and preventing complications. Monitoring blood sugar levels once in the morning (Choice A) is not sufficient for proper diabetes management, as levels can fluctuate throughout the day. Taking medication only when feeling unwell (Choice C) is not recommended as diabetes treatment is based on a regular schedule. Monitoring glucose levels weekly (Choice D) is not frequent enough to provide the necessary information for managing diabetes on a day-to-day basis.

Correct Answer: B

Rationale: Irrigating the bladder using sterile technique is crucial in the care of a client following a transurethral resection of the prostate (TURP). This intervention helps prevent infection and maintains patency of the urinary catheter, promoting healing. Administering antibiotics (Choice A) may be necessary if there is an infection present, but it is not a routine intervention following TURP. Avoiding bladder irrigation (Choice C) is not recommended as it can lead to clot retention and other complications. Inserting a urinary catheter (Choice D) is usually already done during the TURP procedure and is not a postoperative intervention.

Correct Answer: A

Rationale: The correct answer is A: Shortness of breath and weight gain. Early signs of heart failure typically manifest as shortness of breath due to fluid accumulation in the lungs and weight gain due to fluid retention in the body. Choices B, C, and D are incorrect. Fatigue and chest pain are symptoms commonly associated with heart conditions but are not specific early signs of heart failure. Nausea and vomiting are not typically early signs of heart failure. Cough can be a symptom of heart failure, but it is usually associated with other symptoms like shortness of breath rather than being an isolated early sign. Elevated blood pressure is not an early sign of heart failure; in fact, heart failure is more commonly associated with low blood pressure.

Correct Answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.
