Final answer:
In this scenario, the appropriate next step is to discontinue resuscitation measures and notify dispatch or the medical coroner.
Step-by-step explanation:
The next steps that should be taken in this situation is option B: Discontinue all resuscitation measures, and take the next steps of notifying your dispatch and/or local medical coroner, as laid out by protocol.
In this scenario, the patient has a valid DNR order, which clearly states that she does not want any life-saving procedures. As a medical professional, it is crucial to respect the patient's wishes and honor the DNR order. Continuing resuscitation in this case would be against the patient's expressed desires.
Once the decision to discontinue resuscitation measures has been made, it is important to follow the appropriate protocols and notify the necessary authorities, such as dispatch and/or the local medical coroner.
