If a patient has undergone a kidney transplant, what additional precaution should be taken during treatment?

Patients who have undergone a kidney transplant are placed on immunosuppressive medication to prevent rejection of the transplanted organ. This immunosuppression significantly affects the patient's immune response, making them more susceptible to infections and complications during medical treatments.

When treating these patients, premedication, often with antibiotics or other medications, is crucial to mitigate the risk of infections that could arise from procedures due to their compromised immune system. This added precaution helps ensure that the patient’s risk of developing an infection or experiencing adverse effects is minimized during and after treatment.

The other options do not take into account the need for precautions related to the patient's immunocompromised state. Avoiding anesthesia is not typically a requirement, and antibiotics can be essential rather than contraindicated. Additionally, patients usually do not need premedication in other contexts, making a clear understanding of their unique medical condition vital in this scenario.
