. A nurse is assisting with the collection of a bone marrow specimen from a preschooler. Which of the following actions should the nurse take?
Place the child in prone position to expose the posterior iliac crest.
Position the child side-lying to expose the vertebrae.
Place the child supine with legs flexed outward into a frog-like position.
Position the child sitting with their buttocks at the edge of the table.
The Correct Answer is A
A. The posterior iliac crest is the typical site for bone marrow aspiration in children. Placing the child in the prone position allows for proper access to the site while ensuring the child remains safe and stable during the procedure.
B. Positioning the child side-lying would expose the vertebrae but is not an optimal position for accessing the iliac crest for bone marrow aspiration.
C. The frog-like position (supine with legs flexed outward) is not an appropriate position for a bone marrow aspiration, as it does not provide the best access to the iliac crest or posterior iliac crest.
D. Sitting with the buttocks at the edge of the table would not adequately expose the posterior iliac crest, making it unsuitable for bone marrow aspiration.
