You are a pharmacist or pharmacy technician, working at a large hospital. You receive an order for Fukitol, which says "Give patient Fukitol, 1 tablet upon waking each morning and one at noon".
You interpret this to mean:
A: Give twice a day, 1 pill when the patient wakes up and 1 pill at noon.
B: Give one 1 pill each day ONLY if the patient wakes up at noon.
If you answered B, thank you for taking the time to argue with me on the phone this morning. I really appreciated it when you said "maybe you should go back to school".
