Correct Answer: B

Rationale: The correct instruction for taking sucralfate is 1 hour before meals. This timing allows sucralfate to effectively coat the stomach lining and provide a protective barrier against gastric acid, helping to prevent ulcers.

Correct Answer: A

Rationale: An aPTT of 90 seconds is above the therapeutic range for heparin, which typically falls between 60-80 seconds. This indicates that the current heparin dose is too high, and the infusion rate should be decreased to avoid excessive anticoagulation and the risk of bleeding. Monitoring aPTT is crucial in adjusting heparin therapy to maintain it within the therapeutic range.

Correct Answer: C

Rationale: When two inhaled medications are prescribed, waiting 5 minutes between medications allows for optimal absorption and effectiveness of each medication. This ensures that each medication can work properly without interference from the other, improving the client's respiratory condition.

Correct Answer: A

Rationale: It is crucial to monitor ins and outs in patients using ACE inhibitors to assess for renal impairment. ACE inhibitors can affect renal function, potentially leading to renal impairment. Monitoring the patient's fluid balance helps in early recognition of any renal issues and allows for timely interventions to prevent complications.

Correct Answer: A

Rationale: The correct answer is A because warfarin takes several days to reach a therapeutic level and exert its full anticoagulant effect. During this time, the IV heparin is continued to prevent clotting until the warfarin is effective. Both medications are used together temporarily for this reason. Discontinuing heparin prematurely can increase the risk of clot formation. Therefore, the nurse should explain to the client that the IV heparin will be continued until the warfarin reaches a therapeutic level.
