You are a third year medical student on an emergency medicine rotation. The triage nurse tells you that a young mother has brought in her 2 and 1/2 month old baby boy because he “won’t wake up” and has been “shaking”.

You quickly enter the room and find Latisha, a 17 year old first time mom and her son Jamal. Jamal is unresponsive.

What do you do first?
