What is the primary action to take if someone is in shock?

Calling 911 immediately is the primary action to take if someone is in shock because shock is a medical emergency that requires professional help. Time is of the essence in these situations, as shock can lead to severe complications and even death if not treated promptly. When you call emergency services, you ensure that the individual receives the necessary medical attention as soon as possible.

While other actions may sometimes be appropriate in different contexts, they do not address the urgency of the situation as effectively as contacting emergency services. For instance, moving someone to a sitting position or keeping them active could potentially exacerbate their condition if they are in shock. Giving them water to drink might worsen the situation, especially if they are unable to swallow or if their condition requires more immediate medical intervention.
