Like many nurses, the thing I’m always worried about is doing either too much or too little. If I sound an alarm and the patient is OK, then I over-reacted and have untrustworthy clinical judgment. If I don’t call in the cavalry when it’s needed, then I’m negligent and unsafe for patients. You don’t always know because what goes on inside human bodies can be hidden and subtle. This job would be easier if there weren’t such a narrow divide between being the canary in the coal mine and Chicken Little.
