Correct Answer: A

Rationale: A persistent dry cough is a common side effect of lisinopril. Lisinopril is an ACE inhibitor that can cause a cough due to the accumulation of bradykinin. Weight gain, dry mouth, and hyperglycemia are not typically associated with lisinopril use, making them incorrect choices in this scenario.

Correct Answer: B

Rationale: The correct answer is B. The nurse should instruct the client to avoid excessive intake of caffeinated beverages as they can interfere with lithium levels. Option A is incorrect as lithium is usually recommended to be taken on an empty stomach. Option C is not directly related to lithium therapy. Option D is not a typical instruction for lithium therapy.

Correct Answer: B

Rationale: The correct answer is B. Albuterol is a rescue inhaler that should be used during asthma attacks to provide quick relief by opening the airways. Using it daily as a preventive measure is not recommended. Choice A is incorrect because a dry cough is not a common side effect of albuterol. Choice C is incorrect as albuterol does not need to be taken with food. Choice D is incorrect because albuterol is not meant to be used daily for asthma prevention.

Correct Answer: B

Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.

Correct Answer: C

Rationale: The correct answer is C: Peptic ulcer disease. Methotrexate can exacerbate peptic ulcer disease, leading to serious complications. This finding warrants questioning the administration of methotrexate to prevent harm to the client. Choices A, B, and D are not directly contraindicated with methotrexate use. Osteoporosis, hypertension, and immunosuppression are not typically reasons to question the administration of methotrexate for rheumatoid arthritis.
