A nurse is reinforcing teaching with a client who is to undergo a bone marrow aspiration. Which of the following statements should the nurse include in the teaching?

A. "I will hold pressure to the site after the procedure.": Firm pressure is required after a bone marrow aspiration to reduce bleeding because the needle penetrates highly vascular bone tissue. Applying pressure also helps prevent hematoma formation at the puncture site. B. "You will need to fast for 2 hours before the procedure.": Fasting is not required because the procedure is performed using local anesthesia and does not involve sedation in most cases. Clients can eat normally without affecting the accuracy or safety of the aspiration. C. "You will not receive a local anesthetic agent for this procedure.": A local anesthetic is routinely administered to numb the skin and periosteum to reduce discomfort during needle insertion. Although pressure or brief sharp pain may still occur, anesthesia is an essential part of the procedure. D. "You will have the bone marrow taken from your femur.": The posterior iliac crest is the preferred site in adults because it provides easy access and yields adequate marrow safely. The femur is rarely used except in certain pediatric situations or special circumstances.
