In a head-to-toe assessment, which action should be performed if pelvic fractures are suspected?

When pelvic fractures are suspected during a head-to-toe assessment, applying gentle pressure to the iliac crests is an appropriate action. This technique is important as it allows the healthcare provider to assess for any instability or pain in the pelvic region, which can indicate the presence of a fracture. The pelvis is a critical area of the body, and fractures here can lead to significant complications, including internal bleeding.

By applying gentle pressure, the examiner can evaluate the integrity of the pelvis without causing additional harm or exacerbating any injuries. This approach is essential for making informed decisions regarding the patient's further management and potential need for imaging like X-rays or a CT scan, as well as for monitoring for potential shock due to hemorrhage.

Taking actions such as log rolling or performing a quick neurological check can be considered after initial assessments but are not specific evaluations for pelvic injuries. Ordering a CT scan could be warranted eventually but is not a part of the immediate physical assessment. Thus, gentle pressure on the iliac crests is the most appropriate initial action in this scenario.
