Two scenarios here:
1. If is PRN ....NO... patient asks for AS NEEDED. You don't need to monitor on MAR.
But even then you need to have nursing notes about effectivness of med. You gave to him with a goal.... was ok? OR not? Any ASE? What did you do if wasn't ok?
Asses...and ...Call the dr...
2. Is is routinely, YES, you need to monitor hours of sleep Qshift and eventually monitor also and ASE, call the dr and dr will adjust the dose of ambien acording with the number of hour of sleep/or insomnia per shift, or any other ASE noted.
A good nurse is MUST to provide all these inf for rutinely ambien to dr, if the policy and procedure of facility asks for...is not..... is their problem, lol..but you like a GOOD nurse need to fallow up with it in your nursing notes and call the DR is somenthing "unusual" seems to be....
(patient could not sleep after ambien, patien looks like having ASE on ambien, patient refuse ambien ), and let a note to your supervisor related it, annonce next shift.... WRITING!
Next day IDT need to fallow up with and take an action.
Much more, the nurses when they chart about the patient they MUST to write on nursing notes how many hours the patient sleep or not, if dose of ambien was effective or not and/or are present ASE/allergy manifested, and how patient looks like (arousable, slightly arousable, dizinees, drowsiness, sleepy,obnubilated...comatose..OMG, lol)
Be a good nurse even if your policy is not there...look at patient, and remeber the ASE of ambien.
Critical thinking... "day time drowsiness" is not ONLY because he/she could become "more acute sick", but could be also from a ASE of ambien or to a TOO high dose of... THINK!
Monitor, monitor, monitor and think, note, write and report to up levels your assesment , and note again!
