The patient who received 13 units of insulin instead of 3 units should be assessed first for signs of serious hypoglycemia related to insulin overdose. The next patient to be seen is the one whose first vancomycin dose was due at 0600. This patient likely has a serious infection that should be treated promptly, but without more information on the patient’s condition, the first patient to be seen is the one who was given far too much insulin. The patient who requires a vancomycin trough before the next dose is given should be seen next. Although the patient needs to receive the antibiotic promptly, the patient has a certain amount circulating in the bloodstream due to the half-life of vancomycin. Lastly, the patient who was undertreated with insulin should be seen. Although the patient’s glucose level is likely not in range, the patient is less at risk for short term complications than the other patients.
