A patient is post-procedure after a bone marrow aspiration. What position should the nurse instruct the patient to assume for at least 30 minutes after the procedure?
A.
Supine position with legs elevated
B.
Lying flat on the abdomen
C.
Semi-Fowler’s position with the head elevated
D.
Lateral decubitus position with the knees flexed
The Correct Answer and Explanation is:
The correct answer is D. Lateral decubitus position with the knees flexed.
Explanation:
After a bone marrow aspiration, the patient needs to assume a position that minimizes the risk of bleeding and promotes comfort at the site of the procedure. Bone marrow aspiration is typically performed from the posterior iliac crest or, less commonly, the sternum. The procedure involves inserting a needle into the bone to extract a sample of bone marrow for examination. Due to the invasive nature of this procedure, proper positioning afterward is crucial to prevent complications.
Lateral Decubitus Position with the Knees Flexed:
- Minimizes Pressure on the Aspiration Site: After a bone marrow aspiration, particularly when performed from the posterior iliac crest, the lateral decubitus position (lying on the side) with the knees flexed helps to reduce pressure on the aspiration site. This position allows for better support of the pelvic region, where the needle was inserted, and helps to minimize discomfort and potential bleeding.
- Promotes Hemostasis: Flexing the knees and positioning the patient on their side can aid in controlling bleeding at the site of the needle insertion. The position promotes venous return and reduces the likelihood of blood pooling at the site of the procedure.
- Comfort and Stability: This position is generally comfortable for patients following such procedures. It provides stability and support to the areas affected by the needle insertion, making it easier for the patient to rest without additional pressure on the site.
Other Positions:
- Supine Position with Legs Elevated (A): This position is often used for general post-procedure recovery but is not specific to bone marrow aspiration and may not offer adequate protection to the iliac crest site.
- Lying Flat on the Abdomen (B): This position is not ideal as it places pressure on the back and the iliac crest, potentially increasing discomfort and risk of bleeding.
- Semi-Fowler’s Position with the Head Elevated (C): This is a common position for general comfort and respiratory issues but does not address the need for specific support at the bone marrow aspiration site.
In summary, the lateral decubitus position with knees flexed (D) is the most appropriate choice for minimizing complications and ensuring comfort after a bone marrow aspiration procedure.
