Which statement about intraosseous infusion is TRUE?

Intraosseous infusion involves delivering fluids directly into the bone marrow, which allows rapid absorption into the systemic circulation. Aspiration of bone marrow fluid serves as a confirmation that the needle is correctly placed within the medullary cavity. If the needle is correctly positioned, a viscous fluid resembling blood or bone marrow may be aspirated, indicating that the intraosseous access route is appropriate for administering medications or fluids.

This confirmation is critical for ensuring that the infusions will be effective and reducing the potential complications associated with improper placement. While there are indeed specific clinical scenarios where intraosseous access is preferred, particularly during emergencies when intravenous access may be difficult, these factors are not directly related to the particular statement regarding aspiration and positioning.

Intraosseous infusion is a valuable alternative route especially in pediatric patients or emergencies, but it is not recommended for long-term use; therefore, other options, such as intravenous access, are preferred for ongoing resuscitation and therapies.
