Correct Answer: A

Rationale: The correct actions the nurse should take when caring for a client postoperative following a cholecystectomy and reporting pain include changing the client's position. This can help relieve postoperative pain by reducing pressure on the surgical site. Identifying the client's pain level is important but not specific to alleviating postoperative pain. While reminding the client to use incisional splinting can be beneficial, it may not directly address the immediate pain concern. Offering the client a back rub is not typically indicated for postoperative pain relief after a cholecystectomy.

Correct Answer: B

Rationale: Obtaining a 12-lead ECG is crucial in this situation to assess cardiac function due to the elevated potassium level. High potassium levels can lead to dangerous arrhythmias, and an ECG helps in detecting any cardiac abnormalities. Choices A, C, and D are incorrect. Suggesting a salt substitute can further elevate the client's potassium levels. Checking serum sodium levels is not the priority when dealing with high potassium levels. Advising the client to add citrus juices and bananas, which are high in potassium, would worsen the situation.

Correct Answer: C

Rationale: The correct information the nurse should include is that menopausal hormone therapy helps prevent osteoporotic fractures by maintaining bone density. Option A is incorrect as hormone therapy should be taken consistently at the same time each day for optimal effectiveness. Option B is incorrect as menopausal hormone therapy is not primarily aimed at preventing cerebral hemorrhage. Option D is incorrect because taking an extra dose is not recommended if a dose is missed; instead, the missed dose should be taken as soon as remembered, unless it is close to the time for the next dose.

Correct Answer: C

Rationale: The correct answer is Ciprofloxacin. Ciprofloxacin is an antibiotic effective in treating anthrax exposure. Fluconazole (Choice A) is an antifungal medication used for fungal infections, not anthrax. Tobramycin (Choice B) is an antibiotic used for bacterial infections but is not the first line of treatment for anthrax. Vancomycin (Choice D) is also an antibiotic, but it is not the preferred choice for treating anthrax.

Correct Answer: B

Rationale: The correct statement to include is to 'Keep your abdominal muscles tightened when lifting objects.' This practice helps protect the back from injury by providing core stability. Rubbing hands together for 10 seconds when washing them (Choice A) is a good hygiene practice, but not directly related to warehouse work safety. Ensuring 20% or less of calories come from saturated fats (Choice C) is important for overall health but not specific to workplace safety. Engaging in aerobic exercise 2 to 4 days per week for 20 minutes (Choice D) is beneficial for health but not as directly relevant to preventing injuries while working in a warehouse.
