Correct Answer: C

Rationale: The correct answer is C: "I can stop taking my insulin when my blood sugar is normal." This statement indicates a misunderstanding of diabetes management. Here's the rationale: 1. Insulin is a crucial medication for managing diabetes, and stopping it abruptly can lead to serious complications. 2. Blood sugar levels can fluctuate, so stopping insulin when levels are normal is not safe or effective. 3. Proper education should emphasize the importance of consistent insulin use as prescribed by healthcare providers. 4. Choices A, B, and D demonstrate good understanding of diabetes management by focusing on monitoring blood glucose levels, following a healthy diet, and exercising regularly.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation and use of compression stockings. This intervention is crucial post-hip replacement to prevent complications such as blood clots and muscle weakness. Early ambulation helps prevent blood clots by promoting circulation, and compression stockings further aid in preventing deep vein thrombosis. Pain medication (A) is important but not the priority in preventing complications. Providing nutritional support (C) is also important but does not directly prevent post-operative complications. Monitoring for signs of infection (D) is essential but not as immediate as promoting early ambulation to prevent complications.

Correct Answer: A

Rationale: The correct answer is A: Inspecting feet daily for signs of injury. This is crucial for patients with diabetic neuropathy to prevent complications like foot ulcers. Daily foot inspections can catch any signs of injury early, allowing for prompt treatment. It helps in preventing infections and serious complications. Summary of why other choices are incorrect: B: Exercising to improve circulation - While exercise is beneficial for overall health, it may not directly address the risk of injury due to neuropathy. C: Eating more protein-rich foods - While a balanced diet is important for managing diabetes, protein-rich foods do not specifically address the risk of foot injuries in diabetic neuropathy. D: Using tight-fitting shoes to prevent blisters - Tight-fitting shoes can actually increase the risk of blisters and injuries, especially in patients with diabetic neuropathy.

Correct Answer: C

Rationale: The correct answer is C because the small, flat, brown macules described are consistent with lentigines (commonly known as age or liver spots), which are clusters of melanocytes that appear after prolonged sun exposure. This explanation directly addresses the patient's question about the cause of the spots and is supported by the clinical presentation. Choice A is incorrect because decreased hematocrit related to anemia would not cause these specific skin changes. Choice B is incorrect as destruction of melanin due to sun exposure would result in lighter spots, not dark brown macules. Choice D is incorrect because hyperpigmentation related to decreased perfusion and vasoconstriction would present differently and not primarily on sun-exposed areas like the arms and hands.

Correct Answer: A

Rationale: The correct answer is A: Severe headaches and blurred vision. Hypertension can lead to complications such as hypertensive crisis, causing symptoms like severe headaches and blurred vision due to increased pressure in the blood vessels. This can indicate a serious health issue requiring immediate medical attention. Weight loss and dizziness (B), increased appetite and tremors (C), and nausea and vomiting (D) are not typically associated with hypertension complications. It's crucial for the nurse to educate the patient on recognizing these signs to prevent further health risks.
