Final answer:
If a nurse causes severe injury to a patient by abandoning them in distress to make a personal call, they should be reported to the state board of nursing. Correct option is B.
Step-by-step explanation:
If the ambulatory care nurse (Nurse A) noted another nurse (Nurse B) caused severe injury to a patient because Nurse B abandoned the patient in distress to make a personal call, Nurse B should be reported to the state board of nursing. This is the appropriate course of action in cases where a nurse has engaged in misconduct or behavior that has resulted in patient harm. The state board of nursing has the authority to investigate the incident, impose disciplinary measures, and take appropriate action to protect the public.
