When he analysed the ingredients of the medicine he became furious and immediately called Nancy's charge nurse.
'Let me ask you, did you take the medicine I dispensed directly to Miss Nancy for injection?'
That nurse was unsure and obediently responded 'Yes doctor, after receiving the medicine from you, I did take it directly to the ward to inject Miss Nancy.'
'No one else touched the medicine in between?'
Startled by the doctor's serious expression, the nurse thought that something had gone wrong with her work and hurriedly explained.
'No, I'm the only one who touched this medicine. What's wrong, is something wrong with the patient?'
The doctor dropped a piece of paper on the table and slapped it on heavily, his expression extraordinarily serious.
