Q

you are treating a ptnt in anaphylactic reaction, who is U, weak carotid pulse, 64/40BP, and paramedics are 4 mins why. Why would med control deny your giving the epipen? choose 1

paramedics are so close

because the patient is not experiencing breathing compromise

the auto-injector will be ineffective

A

the auto-injector will not be effective.
This is the answer, I think because the BP is so low, potentially the epipen won’t work well.
