Correct Answer: B

Rationale: The correct answer is B. Grapefruit juice can increase the risk of toxicity with simvastatin, so clients should avoid consuming it while on the medication. Choice A is incorrect because the timing of medication administration should be based on healthcare provider instructions. Choice C is incorrect because simvastatin is prescribed to lower cholesterol levels. Choice D is incorrect as monitoring kidney function is not specifically related to simvastatin therapy.

Correct Answer: B

Rationale: Yogurt is the best choice for increasing calcium intake in a client with osteoporosis. It provides around 300-400 mg of calcium per serving, making it an excellent food source for meeting their calcium needs. Broccoli, spinach, and almonds, while nutritious, do not provide as much calcium per serving as yogurt and are not as effective in helping clients with osteoporosis increase their calcium intake.

Correct Answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). The glycosylated hemoglobin test measures average blood glucose levels over the past 2-3 months, providing an indication of long-term glycemic control in clients with diabetes. Choice A, postprandial blood glucose, reflects blood sugar levels after a meal and does not provide a long-term view. Choice C, glucose tolerance test, evaluates the body's ability to process sugar but does not offer a continuous assessment like the HbA1c test. Choice D, fasting blood glucose, measures blood sugar levels after a period of fasting, which is more indicative of immediate glycemic status rather than long-term management.

Correct Answer: B

Rationale: Bacterial vaginosis often presents with a profuse, milky white discharge and a characteristic fishy odor, without significant inflammation, hematuria, or fever. Choice A, frequency, and dysuria are more indicative of a urinary tract infection. Choice C, hematuria, is associated with conditions like urinary tract infections or kidney problems. Choice D, low-grade fever, is not a typical symptom of bacterial vaginosis.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease often develop anemia due to reduced erythropoietin production, leading to decreased red blood cell production. Iron supplementation is frequently required to enhance red blood cell production. Choices B, C, and D are incorrect because in chronic kidney disease, there is a need to restrict phosphorus intake, control carbohydrate intake for blood sugar management, and monitor electrolytes and fluid balance rather than blood glucose levels.
