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. Montelukast is a leukotriene receptor antagonist that is typically taken once daily in the evening for asthma management. Choice A is incorrect as montelukast is not used for acute asthma attacks but rather for the prevention of asthma symptoms. Choice C is also incorrect because montelukast can be taken with or without food. Choice D is misleading as all medications, including montelukast, have potential side effects.

Correct Answer: B

Rationale: Emailing patient information from an unencrypted server violates HIPAA because it exposes sensitive health information to potential breaches. Choice A is not a violation as long as the fax is sent to the correct recipient. Choice C is not a violation if the discussion is done discreetly and within an appropriate setting. Choice D is a recommended practice to ensure patient information is kept secure.

Correct Answer: A

Rationale: Increased thirst is a classic symptom of hyperglycemia due to the body trying to eliminate excess glucose through urine, leading to dehydration and increased thirst. Weight gain, decreased urination, and fatigue are not typical signs of hyperglycemia. Weight gain is more commonly associated with conditions like hypothyroidism or fluid retention. Decreased urination is not a typical symptom of hyperglycemia, as high blood sugar levels usually lead to increased urination. Fatigue can be a symptom of hyperglycemia, but it is not as specific or characteristic as increased thirst.

Correct Answer: C

Rationale: The correct answer is C because sucralfate should be taken on an empty stomach, 1 hour before meals, and at bedtime to coat the ulcer and protect it from stomach acid. Choice A is incorrect because taking it with meals may reduce its effectiveness. Choice B is incorrect as it should not be taken right before bed. Choice D is incorrect as sucralfate should be taken regularly as prescribed, not just when symptoms occur.
