I worked in a medical capacity at one time, and it was practically drilled into us a students, when in doubt, ASK! It's never safe to make assumptions in medical treatment. Giving a patient a sip of water can kill them under the right circumstances. It sounds to me like both the pharmacist and the nurse had doubts, but then acted on their own judgment without double checking with someone else. Either in a rush, or allowing pride or ego to take over.
