Correct Answer: A

Rationale: The correct answer is A: 'Take this medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to enhance absorption. Taking it with food or at bedtime can interfere with its absorption. Calcium supplements should also be avoided when taking levothyroxine as they can reduce its absorption.

Correct Answer: D

Rationale: The correct answer is D. Captopril is known to cause a persistent, dry cough as a common side effect. Instructing the client about this potential side effect is crucial for their awareness. Choices A and B are incorrect because captopril is usually taken on an empty stomach. Choice C is incorrect because captopril can lead to hyperkalemia, so potassium supplements may be necessary in some cases.

Correct Answer: C

Rationale: Respecting cultural dietary preferences enhances patient-centered care.

Correct Answer: D

Rationale: The correct answer is D: Elevated temperature. Cocaine is a stimulant drug that can lead to an increase in body temperature. Hypotension (choice A) is less likely as cocaine tends to increase blood pressure. Memory loss (choice B) and slurred speech (choice C) are not typically immediate effects of recent cocaine use.

Correct Answer: A

Rationale: Polyuria is the correct finding indicating the client is developing diabetes insipidus. Diabetes insipidus is characterized by the excretion of large volumes of diluted urine due to a deficiency in antidiuretic hormone. This results in increased urine output (polyuria) despite adequate fluid intake. Hypertension (choice B) is not typically associated with diabetes insipidus but can be seen in other conditions. Bradycardia (choice C) and hyperglycemia (choice D) are also not typical findings of diabetes insipidus.
