you are called to a 'patient down' at a private residence. as you get inside and into the back bedroom, you can see that there is a woman face down and motionless. she does not appear to be conscious and there is a pool of saliva next to her head. your partner maintains spinal precautions as you roll her onto her back. the husband states that she has a history of heart problems, takes a lot of medications, and has no allergies. what would you do next?
