Fundamentals Question #52

Question

The nurse is preparing the client for a bone marrow biopsy. What position is ideal for this procedure?

Answers

  1. Lateral side-lying
    • Rationale:

      This answer is correct because lateral or side-lying position is used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved. Lateral or side-lying position is when a client is lying on one side of the body with the top leg bent at the knee and hip and the bottom leg relatively straight. Occasionally, the client is asked to lie prone to make the iliac crest more accessible.

  2. Supine
    • Rationale:

      This answer is not correct because supine positioning for a bone marrow aspiration would prevent access to the iliac crest. Lateral or side-lying position is used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved.

  3. Semi-Fowler
    • Rationale:

      This answer is not correct because semi-Fowler is when the client is lying on their back with the bed at 15-45 degree angle. Lateral or side-lying position is used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved.

  4. Lithotomy
    • Rationale:

      This answer is not correct because lithotomy position is used for gynecological examinations or procedures. The client is placed on their back and their feet placed in stirrups. This position would not allow access to the iliac crest. Lateral or side-lying position is used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved.

Overview

Lateral or side-lying position is used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved.

Explanation

Learning Outcomes

Lateral or side-lying position is when a client is lying on one side of the body with the top leg bent at the knee and hip and the bottom leg relatively straight. This position is overall used for client comfort, prevention of pressure ulcers, decreasing pneumonia, pulmonary emboli, and atelectasis. Lateral or side-lying position is also used to perform bone marrow aspiration. This position allows the healthcare provider access to the posterior iliac crest where the bone marrow is retrieved. Occasionally, the client is asked to lie prone to make the iliac crest more accessible.

Test Taking Tip

The client in the left lateral or side-lying position should have everything carefully explained to them. The client has their back to the nurse or provider and every touch or stick should be told to the client since they are unable to see what is going on.
