Right Route
Right Time
Right Documentation
Check the Six Rights at 3 Different Points During Med Administration: - ANSWER-1.

2. Check meds AFTER preparation
3. Check meds at the bedside: also check blood pressure and/or pulse or blood sugars
if needed BEFORE giving meds that affect the BP, pulse, or blood sugars. AND always
check allergy band.
***You will check patient name and DOB as well as check MR # on armband against
