A client who had a kidney transplant last week is receiving cyclosporine. This morning the client reports experiencing a headache and blurred vision. Based on which assessment finding should the nurse withhold the medication until the healthcare provider (HCP) is notified?

A. Advise the client that the healthcare provider (HCP) needs to be made aware of the current diet: Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin by promoting clotting. The healthcare provider must be informed to adjust the medication dose if necessary or provide specific dietary guidance.

B. Suggest that the client replace the leafy vegetables with a protein source such as nuts or beans: Advising the client to eliminate green vegetables is not appropriate because sudden changes in vitamin K intake can destabilize warfarin therapy. Consistency in vitamin K consumption is key rather than abrupt dietary changes.

C. Confirm that the client's diet choices will help the medication be more effective in preventing blood clots: Regular consumption of vitamin K-rich foods without dose adjustment can decrease warfarin's anticoagulant effect, increasing the risk of clot formation. The current diet does not inherently support the intended action of the medication.

D. Commend the client for a healthy lifestyle and encourage the client to continue current diet habits: Although a diet rich in vegetables is generally healthy, with warfarin therapy, any vitamin K intake must be consistent and properly managed. Simply encouraging the client without notifying the provider could lead to therapeutic failure.

A. Use insulin sliding scale until symptoms are resolved: Starting insulin without an evaluation would be inappropriate. A sliding scale may eventually be needed if blood sugars fluctuate, but the priority is to assess the cause of the gastrointestinal symptoms first.

B. Return to the clinic for laboratory tests for an infection: Although an infection could be a cause, nausea, vomiting, and diarrhea in a diabetic client also raise concern for possible medication issues, dehydration, or even metabolic disturbances. Immediate evaluation is necessary before simply ordering lab tests.

C. Schedule a visit for evaluation by the healthcare provider (HCP): New gastrointestinal symptoms could indicate a significant underlying issue such as medication intolerance, dehydration, or even diabetic ketoacidosis (though less common in type 2). An urgent clinical assessment by the HCP is most appropriate.

D. Increase oral fluid intake until these symptoms subside: While staying hydrated is important, advising fluids alone without a thorough assessment risks missing a serious underlying cause. Symptom management should not replace a proper medical evaluation.
