Correct Answer: A

Rationale: The correct answer is A: Alcohol. When taking cyclobenzaprine, it is important to avoid alcohol as it can potentiate the central nervous system depressant effects of the medication. This interaction can lead to increased drowsiness, dizziness, and impaired coordination. Therefore, it is essential for the client to refrain from alcohol consumption while on cyclobenzaprine to prevent these adverse effects and ensure their safety.

Correct Answer: C

Rationale: Prednisone, a corticosteroid, can cause side effects such as hypertension, fluid retention, and weight gain. Hypertension is a common side effect of prednisone due to its impact on sodium and fluid retention in the body. Monitoring blood pressure is crucial to detect and manage hypertension in clients taking prednisone.

Correct Answer: A

Rationale: The correct answer is A: Bleeding. Apixaban is an anticoagulant medication that works by decreasing the blood's ability to clot. One of the significant side effects of apixaban is an increased risk of bleeding. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in the urine or stool, or unusual bleeding or bruising. Monitoring for these signs is crucial to prevent or manage any potential complications associated with the medication.

Correct Answer: D

Rationale: The correct action for the nurse to take is to instruct the client to use acetaminophen for headaches. Acetaminophen is a suitable and safer option for managing headaches associated with calcium channel blockers like diltiazem. It is essential to avoid medications that can interact negatively with diltiazem, such as opioid analgesics, and to not discontinue the medication abruptly without consulting the healthcare provider. Monitoring for medication toxicity through blood samples is not typically indicated for managing headaches in this scenario.

Correct Answer: C

Rationale: Reviewing the most recent coagulation lab values is crucial after receiving multiple doses of a new oral anticoagulant to ensure the patient is within the desired therapeutic range and to prevent adverse events related to over or under-anticoagulation. Notifying the healthcare provider of any concerning findings is important, but it may not be the immediate priority after receiving the third dose. Providing a PRN NSAID for gum discomfort is not typically indicated with oral anticoagulant therapy, as it may increase the risk of bleeding. Completing a medication variance report is more relevant in cases of medication errors or discrepancies, which may not apply in this scenario.
