Correct Answer: C

Rationale: The correct adverse effect associated with vancomycin therapy is an infusion reaction, known as Red Man Syndrome. This reaction presents with rashes, flushing, tachycardia, and hypotension. It is essential to administer vancomycin over at least 60 minutes to prevent these symptoms. Hepatotoxicity, constipation, and immunosuppression are not commonly associated with vancomycin use. Ototoxicity and renal toxicity are significant risks with prolonged vancomycin therapy.

Correct Answer: C

Rationale: The correct answer is C: Fecal-oral. Hepatitis A is primarily transmitted through the fecal-oral route, often from consuming contaminated food or water. Choice A, sexual contact, is not a typical mode of transmission for hepatitis A. Choice B, airborne droplets, is more characteristic of diseases like influenza or tuberculosis. Choice D, bloodborne transmission, is more relevant to hepatitis B and C, not hepatitis A.

Correct Answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin mimics the action of antidiuretic hormone (ADH) by increasing the reabsorption of water in the renal tubules. This leads to decreased urine output, helping to manage symptoms of diabetes insipidus, which is characterized by excessive thirst and urination. Choices A, B, and D are incorrect. Vasopressin does not stimulate the pancreas to secrete insulin, slow the absorption of glucose in the intestine, or directly increase blood pressure.

Correct Answer: B

Rationale: The correct answer is B: Macule. A macule is a non-palpable skin lesion smaller than 1 cm in diameter. In this case, the skin lesion described is less than 0.5 cm, making it consistent with a macule. Vesicle (choice A) is a small blister filled with clear fluid, papule (choice C) is a solid, raised skin lesion less than 0.5 cm in diameter, and nodule (choice D) is a palpable, solid lesion larger than 0.5 cm in diameter. Therefore, choices A, C, and D describe skin lesions that do not match the characteristics of the lesion presented in the question.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for constipation.' Calcium carbonate can cause constipation as a side effect. Educating clients on dietary adjustments, such as increasing fluid intake and fiber consumption, can help alleviate this issue. Choice A is incorrect because calcium carbonate supplementation is used to treat hypocalcemia, not cause it. Choice C is incorrect because calcium carbonate should be taken with food for optimal absorption. Choice D is incorrect because calcium carbonate is available over the counter, not as a prescription medication.
