q4d is every four days, and q4h every four hours. Q4G is not a normal term in drug dosing.
q stands for quaque, meaning every in Latin. qd is every day, q4h is every four hours, etc.
q4 in medical terms means every four, so q4h means every four hours and q4d means every four days.
It means once every three days. q=every, 3=3, d=day(s). (If it said Q4H, it would be once every four hours.)
Nothing by mouth every four hours is a rather nonsensical instruction, but if you were inclined to write and abbreviate it, it would be written "NPO q4h."
