A nurse is teaching a patient with hypertension about lifestyle modifications. Which of the following dietary changes should the nurse emphasize?

Correct Answer: B

Rationale: The correct answer is B: Decrease intake of saturated fats. Saturated fats can raise cholesterol levels, leading to increased risk of heart disease and hypertension. Decreasing intake of saturated fats can help lower blood pressure. Incorrect choices: A: Increasing intake of foods high in sodium can worsen hypertension by increasing blood pressure. C: Increasing intake of processed foods often leads to higher sodium and saturated fat intake, worsening hypertension. D: Decreasing intake of fiber is not ideal as fiber helps in maintaining a healthy weight and managing blood pressure.

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: B

Rationale: The correct answer is B: Monitoring vital signs and oxygen saturation. This is the priority intervention because it allows the nurse to assess the patient's current cardiac status and detect any potential complications early. Monitoring vital signs provides crucial information on the patient's cardiovascular stability, while oxygen saturation levels indicate adequate tissue perfusion. Administering pain medication (A) can be important but not the priority. Deep breathing exercises (C) and providing nutritional education (D) are important but not as immediate as monitoring vital signs and oxygen saturation in a patient with a history of myocardial infarction.

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.

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.
