Correct Answer: A

Rationale: The correct answer is A: Crossing the legs at the knees. This position can cause hip dislocation due to the twisting motion it creates on the hip joint. When the legs are crossed at the knees, it puts stress on the hip joint, potentially leading to dislocation. Choice B: Sitting with the feet flat on the floor is a safe position that does not put undue stress on the hip joint. Choice C: Sleeping on the affected side can also increase the risk of hip dislocation due to the pressure and weight placed on the hip joint in this position. Choice D: Using assistive devices for ambulation is important for stability and support, and it does not directly contribute to hip dislocation if used correctly.

Correct Answer: C

Rationale: Rationale: Choice C is correct as additional questions in a review of systems for a 76-year-old patient should address age-related changes. This allows for better assessment of potential health issues specific to older adults. Choice A is incorrect as questions may vary based on age. Choice B is incorrect as age alone does not dictate question changes. Choice D is incorrect as a review of systems is important at all ages for comprehensive patient assessment.

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.

Correct Answer: A

Rationale: The correct answer is A: Severe headaches and blurred vision. These symptoms can indicate a hypertensive crisis, a severe complication of hypertension. Headaches and blurred vision are signs of potentially dangerous high blood pressure levels. Weight loss and fatigue (B), increased appetite and tremors (C), and nausea and vomiting (D) are not typical complications of hypertension and do not directly relate to the cardiovascular effects of high blood pressure. Monitoring for severe headaches and blurred vision is crucial for early detection and management of hypertensive crises.

Correct Answer: C

Rationale: The correct answer is C because it indicates a misunderstanding about hypertension management. Patients should continue taking medication even if blood pressure is normal to prevent future complications. Monitoring blood pressure regularly (A) is important for tracking progress. Taking medication as prescribed (B) is crucial for controlling blood pressure. Reducing sodium intake (D) helps lower blood pressure. Choice C is incorrect as stopping medication prematurely can lead to uncontrolled hypertension.
