What is the first step you should take when a 3-month-old infant is found unresponsive and cold?

When encountering an unresponsive and cold 3-month-old infant, the first appropriate action is to carefully inspect the environment. This step is crucial for ensuring the safety of both the infant and the responder. By assessing the environment, you can identify potential hazards that could pose risks to the infant or yourself, such as electrical sources, sharp objects, or other dangers.

Additionally, assessing the situation allows the responder to determine whether the infant is in a safe location for providing care. This step also includes checking for any signs that might indicate the cause of the unresponsiveness, such as signs of trauma or the presence of other individuals who may need assistance.

Engaging in resuscitative measures, performing CPR, or using an AED without first ensuring the environment is safe could lead to further complications or harm. Therefore, securing a safe environment is the foundational first step before taking further actions to address the infant's health condition.
