Question

How do you transcribe(medically) the term "once-a-day"?

Answer 1

qd means daily or once a day.

qod is every other day.

edit:  Sorry med student.  Your abbreviations may be correct wherever you are from, but mine are the ones standardly used in USA.  I know there are other acceptable ones, but mine are not incorrect and have been the JCHCO approved ones used in every hospital where I have worked.

BID is twice a day

TID is three times a day

QID is 4 times a day

HS is at bedtime

Answer 2

"qd" - each day, which comes from the latin quaque die

to the poster above - OD or od is used for right eye, or oculus dextere

bd should be bid - bis in die - twice a day

by using latin based terminology it creates an accepted system through various industries, although you will see some variations facility to facility

Answer 3

once a day - od

twice a day - bd

3 times a day - tds

4 times a day - qds

Answer 4

The "med" student above is incorrect.  QD is once daily.
