roger, a pharmacist in a hospital, is working in the discharge pharmacy filling medications for patients who are going home. he sees a prescription for ciprofloxacin, an antibiotic, and he asks his pharmacy technician mike to fill it quickly, as the patient is waiting and anxious to leave. mike checks the shelves and sees they are out of ciprofloxacin, but they do have levofloxacin (an antibiotic in the same class that covers most, but not all, of the same types of infections). mike knows he should usually check with the prescribing physician before making a substitution. however, in the interest of efficiency in this particular case, mike deems it ok to go ahead. he substitutes the medications. this is an example of what type of unsafe act?
