Special Situations
Enteral and G-Tube Medications
Medications through a feeding tube are outside the medication aide role unless your state specifically allows them; where it does, flush the tube with water before and after and give each drug separately to prevent clogging.
Use liquid forms when available and do not crush extended-release or enteric-coated drugs without checking.
Coordinate with the nurse to hold tube feedings when a drug must be given on an empty stomach.
Blood Glucose and Insulin
Insulin injections, including sliding-scale doses, are outside the medication aide role unless your state specifically allows them; where they are allowed, the dose follows the ordered scale for the blood glucose result.
Report signs of low blood glucose (shakiness, sweating, confusion, fast heartbeat) to the nurse at once and follow the facility's hypoglycemia protocol.
For hyperglycemia (high glucose), follow the ordered protocol and report the reading rather than giving carbohydrates.
PRN Judgment
Give PRN medications only when the resident meets the ordered indication and within the allowed interval.
Document the reason, time, and the resident's response after a PRN dose.
Do not give PRN drugs on a fixed schedule or withhold them when the criteria are met.
Adverse Reactions and When to Notify the Nurse
Recognize severe allergic reactions (hives, lip swelling, breathing difficulty) as emergencies requiring immediate help.
Notify the nurse for adverse reactions, lack of expected effect, refusals, or values outside a hold parameter.
Stop administration if a resident coughs or chokes and address airway safety before continuing.
Geriatric Considerations
Aging can slow drug metabolism and increase sensitivity, raising the risk of side effects and falls.
Monitor older adults closely and report changes such as dizziness or confusion.
Expect that lower doses and slower adjustments ('start low, go slow') often apply to older residents.
