The dilemma

The system clearly shows the stranger is next in the queue. When two patients are equally urgent, the rule is first in, first served. Your sister's breathing is failing fast. You have the authority to manually override the bed assignment, but doing so breaks the ethics policy you swore to uphold.

Your options

1. Follow the triage protocol. The rules exist to prevent exactly this kind of bias.
2. Override the system. She is your sister, and your primary duty is to her.
3. Check their charts to see who has the higher statistical chance of survival.
