Wrong Tablets Schedule

A doctor is going round the ward with a nurse and they come to the first bed where the chap is laying half dead.

- Did you give this man two tablets every eight hours? - asks the doctor.

- Oh, no, I gave him eight tablets every two hours! - replies the nurse.

At the next bed the next patient also appears half dead.

- Nurse, did you give this man one tablet every twelve hours?

- Oops, I gave him twelve tablets every one hour - replies the nurse.

Unfortunately at the next bed the patient is well and truly deceased, not an ounce of life.

- Nurse, did you prick his boil? - asks the doctor.

- OH MY GOODNESS! - replies the nurse.
