Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Monitoring blood glucose levels regularly allows for timely adjustments in treatment. 2. It helps in preventing hypoglycemia or hyperglycemia complications. 3. Enables the patient to understand how their lifestyle choices impact their blood sugar levels. 4. Empowers the patient to make informed decisions regarding their diabetes management. Summary of why the other choices are incorrect: B: Limiting physical activity can lead to complications like obesity and decreased insulin sensitivity. C: Diet should focus on balanced nutrition, not just low-fat or high-protein, to manage diabetes effectively. D: Taking insulin regardless of blood sugar levels can result in hypoglycemia or poor blood sugar control.

Correct Answer: D

Rationale: The correct answer is D: Administer morphine. The rationale is that vomiting after surgery can be a side effect of pain medication such as morphine. By administering morphine, the pain is reduced, which can help alleviate the vomiting. This intervention targets the root cause of the vomiting. Other choices are incorrect because: A: Administering antiemetics may help with nausea but does not address the underlying cause of vomiting. B: Placing the client in a supine position may worsen vomiting due to increased abdominal pressure. C: Encouraging deep breathing may help with relaxation but does not directly address the vomiting caused by pain.

Correct Answer: A

Rationale: The correct answer is A: Elevate the affected leg. This is the first action because elevating the leg helps reduce swelling and improve blood flow, reducing the risk of complications from the DVT. It also helps alleviate pain. Choice B: Applying compression stockings can be helpful in preventing DVT, but it is not the first action to take once it has developed. Choice C: Providing leg elevation is similar to choice A, but it lacks the specificity of elevating the affected leg to address the DVT directly. Choice D: Administering compression therapy may be necessary, but it is not the initial action to take when a client develops a DVT.

Correct Answer: A

Rationale: The correct answer is A because it helps differentiate between orthopnea (difficulty breathing when lying down) and paroxysmal nocturnal dyspnea (sudden awakening due to difficulty breathing). By asking about worsening symptoms when lying down, the nurse can assess if the patient has orthopnea, a classic symptom of heart failure. Choices B, C, and D are incorrect because they do not specifically target the nighttime breathing difficulty associated with heart failure.

Correct Answer: B

Rationale: The correct answer is B: Avoiding environmental allergens and smoking. Environmental allergens and smoking are common triggers for asthma attacks. Avoiding these triggers can significantly reduce the risk of exacerbations. Over-the-counter medications may provide symptomatic relief but do not address the underlying triggers. Increasing physical activity can be beneficial but may also trigger asthma attacks in some individuals. Limiting fluid intake to reduce mucus production is not a recommended strategy for managing asthma triggers.
