What is the medical abbreviation meaning once a day at bedtime?

Answer 1

Nocturnal is used generally, not just in the medical-nursing fields. Since nocturnal means night, and the general assumption historically was that most people sleep at night, the term now may refer to "while sleeping" even though nocturnal means "at night". Examples from medicine and nursing include:

1. nocturnal bedwettting - involuntary loss of urine during sleep
   
2. nocturnal SOB - shortness of breath during sleep

Answer 2

You would say "qhs" for once a day, at night.

Answer 3

Nocturnal means pertaining to the night but it is not really a medical term but a scientific term.

Answer 4

Nocte is the medical term meaning night. A related abbreviation, hs, means at hour of sleep (i.e. bedtime).

Answer 5

OD nocte

Answer 6

qhs means once a day at bedtime
