A nurse is teaching a client about a iliac crest bone marrow biopsy. Which statement indicates understanding?

• A. This test will be performed while I am lying flat on my back.
• B. I will need to stay in bed for about an hour after the test.
• C. This test will determine which antibiotic I should take for treatment.
• D. I will receive general anesthesia for the test.

Answer: (B)

Postprocedure observation for bleeding at the biopsy site is the key concept. After an iliac crest bone marrow biopsy, there’s a small risk of bleeding where the marrow was punctured. Staying in bed for about an hour allows the nurse to apply ongoing pressure as needed, monitor for any bleeding or changes in vital signs, and ensure the site is healing properly before the patient resumes activity. The procedure is done with local anesthesia, and the patient is positioned on the side or in a prone position to access the posterior iliac crest, not lying flat on the back. General anesthesia isn’t used for this diagnostic procedure, and it doesn’t determine antibiotic therapy. Postcare also includes keeping the dressing clean and dry and avoiding heavy lifting for 24–48 hours.
