A nurse is assisting in the plan of care for a client who is scheduled to have a renal biopsy. Which of the following actions should the nurse include in the plan? (Select all that apply).

A. Complete coagulation studies prior to the procedure: Renal biopsy is an invasive procedure with risk of bleeding. Assessing coagulation studies (PT, aPTT, platelet count) helps identify bleeding tendencies and reduces the risk of hemorrhagic complications. B. Maintain a clear liquid diet 4 hr prior to the procedure: Fasting is generally not required for a percutaneous renal biopsy, unless sedation or anesthesia is planned. A strict clear liquid diet is not a standard preparation in most cases. C. Collect a urine specimen prior to the procedure: Obtaining a baseline urine specimen allows evaluation of pre-procedure renal function, hematuria, or proteinuria. This helps in comparing post-procedure urine output and detecting potential complications such as bleeding. D. Obtain an informed consent prior to the procedure: Informed consent is legally and ethically required before a renal biopsy. The client must understand the risks, benefits, and alternatives before proceeding with an invasive diagnostic procedure. E. Administer diphenhydramine prior to the procedure: Antihistamines are not routinely indicated for renal biopsy unless the client has a known allergy to contrast dye or medications used during sedation.
