> 5. Police Officer Darious arrives to the scene of a suspected overdose where the victim is not responding. He administers Naloxone from his department provided kit. The victim is still not responding, but has a pulse. How long should Officer Darious wait to administer another dose of Naloxone if the victim does not respond after CPR?

> (A) Three to five minutes

> (B) Six to eight minutes

> (C) Three to five seconds

> (D) Ten to fifteen minutes

If the victim has a pulse, why is Officer Darious giving them CPR? He needs to follow directions better.

If the victim has a pulse but is not breathing, CPR is indicated.

As I understand it, rescue breathing is indicated.

Yeah that’s the P in CPR.

Guidelines were changed for laypeople a while back because it turned out continuous chest compressions moved enough air and was more impactful in the first few minutes.

Yup.

The reasoning I heard was that more people are comfortable giving chest compressions than rescue breaths, and we wanted to encourage people to help even if they weren't comfortable with rescue breaths

That's part of it.

> Available evidence strongly support the superiority of bystander compression-only CPR. Reasons for the best efficacy of chest compression-only CPR include a better willingness to start CPR by bystanders, the low quality of mouth-to-mouth ventilation and a detrimental effect of too long interruptions of chest compressions during ventilation.

People don't want to make out with a stranger, they don't do it very well, and pausing chest compressions detracts from it.

Based on my understanding of how questions are written and nothing else, I will guess the correct answer is A.

Yep that's clearly the answer they're looking for, but it's still a shit question.
