During your assessment of a 29-year-old female with significant deformity to her left elbow, you are unable to palpate a radial pulse. Your transport time to the hospital is approximately 40 minutes. You should:

Applying gentle manual traction in line with the limb and reassessing for a pulse is the appropriate action in this scenario because it helps to potentially restore circulation by alleviating any possible compression or displacement of blood vessels caused by the deformity. When a significant deformity is present, particularly in joints like the elbow, it could compromise blood flow and lead to irreversible damage if not addressed.

By applying gentle traction, you give the soft tissues and the vessels the opportunity to return to their normal position, which may allow the radial pulse to be palpated again. It is crucial to ensure that no further injury is caused during this process, which is why the traction should be gentle and in line with the limb's natural alignment. After applying traction, reassessing for a pulse is vital in determining if circulation has been restored before making further decisions on how to manage the injury.

The other options involve actions that may be less appropriate given the severity of the deformity or the risk of further injury. For example, manipulating the elbow to restore circulation could lead to more damage or complications. Furthermore, splinting the elbow in its current deformed position might not address the potential compromise in circulation, and straightening the arm could exacerbate any existing injuries. Therefore, gentle traction
