Correct Answer: A

Rationale: The correct answer is A: 'You should wear a protective eye shield while sleeping.' After cataract surgery, wearing a protective eye shield while sleeping is crucial to prevent accidental injury to the eye. Choice B is incorrect because patients should indeed avoid bending over, but it is not the most important instruction among the options provided. Choice C is incorrect because applying pressure to the eye if pain is felt can be harmful and should not be advised. Choice D is incorrect because patients should not resume wearing their regular glasses immediately post cataract surgery; they should wait until their healthcare provider permits.

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: C

Rationale: The correct intervention the nurse should include in the plan of care for a client with heart failure is to monitor the client's weight daily. Daily weight monitoring is essential to assess fluid balance and detect any signs of worsening heart failure. Limiting fluid intake to 1,500 mL per day (Choice A) may be appropriate in some cases, but it is not the initial priority for this client. Encouraging the client to walk every 2 hours (Choice B) is generally beneficial for mobility but may not be directly related to managing heart failure. Administering oxygen via nasal cannula at 2 L/min (Choice D) is a supportive measure for hypoxia but does not directly address heart failure management.

Correct Answer: C

Rationale: The correct answer is C: Fever. When a client is taking clozapine, fever can indicate serious conditions such as infection or severe reactions, which need immediate medical attention. Constipation (choice A), blurred vision (choice B), and dry mouth (choice D) are common side effects of clozapine but are not as urgent as fever. Constipation can be managed with dietary changes or medications, blurred vision can improve over time, and dry mouth can be relieved with frequent sips of water.

Correct Answer: B

Rationale: The correct answer is to inject the medication into the lateral abdominal wall when administering enoxaparin. This is the recommended technique to ensure proper absorption and prevent tissue damage. Choice A is incorrect because enoxaparin should be administered subcutaneously, not intramuscularly. Choice C is incorrect as massaging the injection site after administration is not recommended, as it can cause bruising and discomfort. Choice D is incorrect because the prefilled syringe should not be discarded after expelling the air bubble; it should be used for the injection.
