The nurse is preparing the client for a bone marrow aspiration at the posterior iliac crest. What would be the best position for the nurse to place the client in for the test?
- A. Head of the bed in a 90?° semi-Fowler's position
- B. Prone position
- C. On the side or back
- D. Lithotomy position
Correct Answer: C
Rationale: The client should be positioned on the back or side to facilitate access to the aspiration site. The 90?° semi-Fowler's and prone position would not allow adequate access to the bone marrow aspiration site. The lithotomy position is used for genitourinary and gynecological testing and procedures.

The nurse is discussing vitamin replacement with a client in the clinic. Which vitamin should the nurse discuss with the client in order to increase the absorption of folic acid and iron?
- A. Vitamin Bâ??â??
- B. Vitamin C
- C. Vitamin B6
- D. Vitamin E

A client is being treated for anemia and has a hemoglobin level of 9.6 g/dL. What does the nurse understand is the basic nutritional component of heme in hemoglobin that the client may be deficient in?
- A. Folic acid
- B. Copper

- A. 13.0 g/dL
- B. 10.2 g/dL
- C. 5.0 g/dL
- D. 11.4 g/dL

The nurse is assisting the physician with obtaining a sample to determine the status of blood cell formation. What type of procedure will the nurse have prepared the client for?
- A. A bone marrow aspiration
- B. A Schilling test
- C. A thoracentesis
- D. A urine sample
Correct Answer: A
Rationale: A bone marrow aspiration is performed to determine the status of blood cell formation. In this procedure, the physician applies local anesthesia and removes bone marrow from the posterior iliac crest or the sternum. The marrow is examined for the types and percentage of immature and maturing blood cells.
The nurse will be assisting the physician with a bone marrow aspiration. Where should the nurse cleanse, clip hair, and drape the skin prior to the procedure?
- A. Over the posterior superior iliac crest.
- B. Over the anterior tibia
- C. Over the radius
- D. Over the metatarsal area
Correct Answer: A
Rationale: The posterior superior iliac crest is the preferred site because no vital organs or blood vessels are nearby. The anterior tibia, radius, or metatarsal area are not used for bone marrow aspirations.
