How should a first responder treat a patient in shock?

A first responder should treat a patient in shock primarily by ensuring their airway is open, providing oxygen if possible, and keeping them warm. This approach is critical because shock can lead to inadequate oxygen delivery to vital organs, and maintaining an open airway is essential for effective breathing. Administering oxygen helps to enhance oxygenation, which may be compromised due to shock.

Keeping the patient warm is also important as shock can lead to hypothermia, especially if the body is unable to maintain temperature due to reduced blood flow. A warm environment helps support the patient's core temperature, improving overall outcomes.

The other options, while they might contain elements of care, are not as effective or appropriate in the acute treatment of shock. Simply positioning the patient in a sitting position can lead to further complications and may not support optimal blood flow. Monitoring vital signs is important but insufficient on its own, as it does not directly address the immediate needs of a patient in shock. Administering medication without proper assessment and oversight can be dangerous and should only be done by qualified medical personnel in a controlled environment.
