Correct Answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increased sodium intake (choice A) is not recommended as it can raise blood pressure. Decreasing potassium intake (choice B) is not advisable as potassium helps regulate blood pressure. Increased cholesterol intake (choice D) is also not recommended as high cholesterol levels can contribute to cardiovascular issues, including hypertension.

Correct Answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

Correct Answer: D

Rationale: Correct. Effectively managing personnel is indeed the most crucial and difficult management skill required of a practical nurse. This skill involves supervising, motivating, and coordinating the work of other healthcare staff, ensuring optimal patient care. Choices A, B, and C are important tasks but do not necessarily involve the same level of complexity and interpersonal skills required for managing personnel in a healthcare setting.

Correct Answer: C

Rationale: The correct answer is C. Smoking, especially in clients over 30, increases the risk of thromboembolic events, making oral contraceptives contraindicated. Choice A (More than 30 years of age) is not a direct contraindication for oral contraceptives. Choice B (Had two multiple pregnancies) is not a factor that contraindicates the use of oral contraceptives. Choice D (Has a history of borderline hypertension) is not a specific contraindication for oral contraceptives unless it is severe or uncontrolled hypertension.

Correct Answer: B

Rationale: The correct answer is B. Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can indicate fluid retention or loss. Measuring and recording fluid intake and output (choice A) is important but may not reflect total body fluid status accurately. Assessing vital signs (choice C) and checking the client's lungs for crackles (choice D) are important assessments but do not directly provide the most accurate monitoring of fluid status.
