Diagnostic Tests

A nurse is preparing a client for a bone marrow biopsy. Which nursing intervention is most important to implement before the procedure?

1 Obtain informed consent and verify the client understands the procedure ✓ 정답
2 Administer prescribed analgesic medication 30 minutes before the procedure
3 Position the client in prone position for posterior iliac crest access
4 Prepare the biopsy site with antiseptic solution

해설

Informed consent is the priority before any invasive procedure to ensure client autonomy and understanding. Other interventions are important but secondary to legal and ethical consent requirements.

Critical Nursing Action Before Bone Marrow Biopsy

The most important nursing intervention before a bone marrow biopsy is to obtain informed consent and verify that the client understands the procedure. A bone marrow biopsy is an invasive procedure that carries risks such as bleeding, infection, and pain. Legally and ethically, the client must provide voluntary, informed consent before the procedure can begin, and the nurse is responsible for verifying that this consent is properly obtained and documented. While other interventions are also important components of pre-procedure care, they are dependent on or secondary to the foundational requirement of informed consent.

Why the Other Options Are Not the Highest Priority

Administering prescribed analgesic medication is an important comfort measure, but it cannot be performed until consent is confirmed. Furthermore, the timing of administration (30 minutes prior) is a subsequent step that follows consent verification. The provided research on foot reflexology highlights that patients undergoing bone marrow aspiration experience considerable pain and anxiety, which reinforces the importance of addressing comfort ^[1]. However, a pharmacological or non-pharmacological intervention for pain is a dependent nursing action that requires a prior order and a consented patient.

Positioning the client in a prone position for posterior iliac crest access is a correct positioning strategy for the most common biopsy site. However, this is a procedural step that occurs after consent is obtained and immediately before the biopsy begins. It is a technical preparation, not a legal and ethical prerequisite.

Preparing the biopsy site with an antiseptic solution is a critical step for infection prevention, but like positioning, it is a final preparatory action performed on a client who has already consented. It does not take priority over the initial step of ensuring the client’s right to self-determination is respected.

Clinical Reasoning and the NCLEX-RN Framework

In the NCLEX-RN prioritization framework, issues related to legal and ethical rights, such as informed consent, are consistently ranked as the highest priority. This falls under the Safe and Effective Care Environment category, specifically Management of Care. The nurse must first ensure the client’s legal protection and understanding before any other preparatory task. The study on reflexology underscores that the procedure is a significant source of distress, making a thorough verification of understanding—a core component of the informed consent process—even more crucial to ensure the consent is truly informed ^[1]. The nurse’s role is not just to witness a signature but to act as a client advocate, confirming that the provider has explained the procedure, its risks, benefits, and alternatives, and that the client can verbalize this understanding without coercion.
