Correct Answer: D

Rationale: The correct answer is D: 'You should avoid taking this medication with dairy products.' Ciprofloxacin should not be taken with dairy products as they can interfere with the absorption of the medication. Choice A is incorrect because ciprofloxacin should not be taken with antacids containing aluminum or magnesium. Choice B is incorrect as there is no specific limitation on caffeine intake associated with ciprofloxacin. Choice C is incorrect as ciprofloxacin does not typically cause urine to turn dark brown.

Correct Answer: B

Rationale: The correct action to verify a client's identity when administering medications is to scan the client's facility identification band. This method ensures accuracy and helps prevent medication errors. Asking the client's full name (Choice A) may not be reliable as names can be similar, leading to confusion. Calling the client's name (Choice C) may not be effective if there are multiple clients with the same name in the facility. Verifying with a second nurse (Choice D) is an important safety measure for certain tasks but is not specifically for verifying a client's identity.

Correct Answer: B

Rationale: Corrected Rationale: Low prealbumin levels are indicative of malnutrition, which is common in individuals with anorexia nervosa. Iron levels, serum creatinine, and calcium levels are not typically affected in the same way by anorexia nervosa, making choices A, C, and D incorrect.

Correct Answer: B

Rationale: The correct answer is B: Persistent cough. Enalapril is an ACE inhibitor that can cause a persistent cough as a common side effect. This symptom should be reported to the healthcare provider to evaluate if a medication adjustment is needed. Choices A, C, and D are not typically associated with enalapril use and are less likely to be directly related to the medication. Increased heart rate, constipation, and sweating are not commonly linked to enalapril, so they are not the priority findings to report in this case.

Correct Answer: C

Rationale: A blood glucose level of 200 mg/dL indicates hyperglycemia and should be reported for potential insulin adjustment.
