One day, the charge nurse dropped a chart down in front of me: "You forgot to write parameters for the Metformin."
Now usually you write parameters for blood pressure meds. Like if the patient's blood pressure is 75/30, you might not want them to get a medication that will lower their blood pressure. But Metformin is an oral medication for diabetes, which doesn't work immediately like insulin does but instead is effective over a longer period of time.
I didn't know how to react to this request. Finally I said, "I never write parameters for Metformin."
"Well, you should," she said.
I was exhausted and overwhelmed with work, as usual, and I actually tried for a second to think of a parameter I might write for Metformin. The only thing I could think of was: Hold if patient stops having diabetes. I almost said that. Instead, I just said, "Metformin doesn't cause hypoglycemia. I want the patient to get it no matter what."
