A: This question is answered in OAR 851-0063. A CNA is limited to the administration of over-the-counter (OTC) bowel evacuation suppositories, topical barrier skin creams/ointments, anti-fungal ointments/powders, and pediculicides (treatment for lice) – and only when directed by the RN plan of care (or the LPN's focused plan of care). The CNA may not administer medications beyond those identified in OAR 851-063 - even if given specific instructions to do so by the nurse. Additionally, assisting a client to take their medications is also not within the authorized duties for the CNA.
