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 is incorrect as age alone is not a contraindication for oral contraceptives. Choice B is incorrect as having multiple pregnancies is not a contraindication for oral contraceptives. Choice D is incorrect as borderline hypertension is not a strict contraindication for oral contraceptives.

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys may not effectively filter excess potassium from the blood, leading to hyperkalemia. Calcium, iron, and zinc do not need to be avoided specifically in chronic renal failure unless there are other underlying reasons or complications.

Correct Answer: B

Rationale: The correct answer is B, 'Personal/professional development.' This category involves educating individuals in various aspects, including history and traditions. In this case, educating soldiers in the history and traditions of the service falls under personal/professional development rather than the other options provided. Choice A, 'Accountability,' focuses on responsibility and answerability, not education. Choice C, 'Individual training,' pertains more to specific skill development rather than broader education on history and traditions. Choice D, 'Military appearance/physical condition,' is related to maintaining physical standards and image, which is not directly relevant to educating soldiers in history and traditions.

Correct Answer: B

Rationale: Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can reflect fluid retention or loss. Measuring and recording fluid intake and output (Choice A) is important but may not provide immediate changes in fluid status. Assessing vital signs (Choice C) can offer some information but may not be as specific to fluid status as daily weighing. Checking the client's lungs for crackles (Choice D) is more related to assessing respiratory status rather than direct fluid monitoring.

Correct Answer: B

Rationale: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries. Choices A, C, and D are incorrect. Hyperthyroidism, underweight, and poor appetite do not directly cause atherosclerosis. Similarly, constipation, peptic ulcer disease, pancreatitis, kidney failure, edema, and sodium retention are not among the primary causes of atherosclerosis.
