A nurse is preparing a client for the operating room. A nurse is planning care for a client who is scheduled to have a kidney biopsy. Which of the following interventions should the nurse include in the plan? (Select all that apply)

A. Verify informed consent: A kidney biopsy is an invasive procedure that carries significant risks such as bleeding. Confirming that the client has signed an informed consent form is a legal and ethical requirement before proceeding. B. Administer diphenhydramine (Benadryl) prior to procedure: Diphenhydramine is not typically required before a kidney biopsy. It is an antihistamine used for allergic reactions and is not a standard pre-procedural medication for this test. C. Obtain coagulation studies: Coagulation studies such as PT, aPTT, and INR must be reviewed to assess bleeding risk. Kidney biopsies carry a risk of hemorrhage, so normal clotting status must be confirmed. D. Collect a urine specimen prior to procedure: A pre-procedure urine sample is important to check for infection or significant hematuria, which can influence the safety and timing of the biopsy. E. Ensure NPO status: Clients are typically kept NPO for 6 to 8 hours before the biopsy to reduce the risk of aspiration if sedation or analgesia is used during the procedure.
