In a medical emergency, what is the first step a detention officer should take?

In a medical emergency, activating emergency medical services is the first step a detention officer should take because it ensures that professional medical assistance is on the way. This action is critical as it brings trained medical personnel to the scene who can provide appropriate care and treatment. Quick and efficient activation of emergency services can significantly impact the outcome of the situation, especially if the medical issue is severe or life-threatening.

While providing basic first aid and ensuring the safety of all detainees are also important aspects of responding to a medical emergency, they can often be initiated after medical assistance has been called. Additionally, asking the detainee what's wrong may help gather information, but it should not delay the process of getting professional help. Thus, activating medical services serves as a crucial and immediate response that prioritizes the health and safety of the detainee in need.
