Medication administration is one of the most high-stakes skills a medical assistant performs. Errors can injure patients. The good news is that the profession has built a systematic framework to prevent mistakes — the rights of medication administration. Learn these cold, because they show up on the CCMA exam and they matter every single day in clinical practice.
The 7 Rights of Medication Administration
The original five rights have expanded over time. Most credentialing bodies now recognize seven. Know all of them.
1. Right Patient
Verify identity using two patient identifiers before giving any medication. Name and date of birth is the standard combination in most outpatient settings. Never rely on a room number or a face you recognize. People get mixed up. Use the armband in hospital settings. Ask the patient to state their name — do not just read the name and nod.
2. Right Drug
Check the medication label three times: when you pull it from storage, when you prepare it, and right before you administer it. Compare the label to the medication order or MAR (Medication Administration Record). Generic and brand names both need to be familiar to you. A lot of errors happen because two drugs have similar-sounding names — lisinopril and lispro, for example.
3. Right Dose
Verify the dose against the order. Calculate if needed. If your math gives you a dose that seems unusually high or low, check again. Question orders that do not make sense. A 10-fold dosing error is one of the most common medication mistakes in clinical settings.
4. Right Route
Some medications can only be given one way. Others are formulated for multiple routes but have different dosing by route. Giving a medication by the wrong route can cause serious harm — IV medications given orally, or oral medications injected, can both be fatal in some cases.
5. Right Time
Give medications at the prescribed time and frequency. Know common abbreviations: QD (daily), BID (twice daily), TID (three times daily), QID (four times daily), PRN (as needed), AC (before meals), PC (after meals), HS (at bedtime). Timing matters most for antibiotics, insulin, and medications with narrow therapeutic windows.
6. Right Documentation
Document immediately after administration — not before, not an hour later. Record the drug name, dose, route, site (for injections), time, and your name or initials. In an EHR, this usually means signing off the MAR entry. If a patient refuses a medication, document that too, including that you educated the patient.
7. Right Reason
Understand why the patient is getting the medication. This right protects against transcription errors and catches situations where a new allergy or contraindication has developed. If you cannot identify a clear reason for the medication, clarify with the provider before administering.
Routes of Medication Administration
Route determines how fast a drug acts and how it is absorbed. MAs need to know the common routes, their abbreviations, and key considerations for each.
Oral (PO)
Swallowed tablets, capsules, or liquids. Slowest onset. Most convenient. Considerations: patient must be able to swallow, not NPO, and have intact GI absorption. Some medications must not be crushed — extended-release formulations, enteric-coated tablets.
Sublingual (SL)
Placed under the tongue and absorbed directly into the bloodstream through the mucous membranes. Faster than oral. Used for nitroglycerin and some other cardiac medications. Instruct the patient not to swallow the tablet or eat/drink until it dissolves completely.
Topical
Applied to skin or mucous membranes. Includes creams, ointments, patches, eye drops, ear drops, and nasal sprays. Wear gloves — some topical medications (nitroglycerin ointment, fentanyl patches, hormone creams) are absorbed through your skin too. Rotate patch sites and document location.
Inhaled
Delivered directly to the respiratory tract via nebulizer or metered-dose inhaler (MDI). Fast onset for respiratory conditions. Technique matters — poor inhaler technique significantly reduces drug delivery. Teach and demonstrate proper technique to patients.
Parenteral
Any route outside the GI tract, but commonly refers to injections. Main types:
- Intradermal (ID): Into the dermis, just under the epidermis. Used for TB skin tests (PPD) and allergy testing. Forms a wheal. Needle bevel up, 5-15 degree angle.
- Subcutaneous (SubQ): Into the fatty tissue beneath the skin. Used for insulin, heparin, some vaccines. 45-90 degree angle depending on patient size.
- Intramuscular (IM): Into muscle tissue. Faster absorption than SubQ. Common sites: deltoid (vaccines, small volumes), vastus lateralis (infants), ventrogluteal. Z-track technique reduces leakage and tissue irritation.
- Intravenous (IV): Directly into a vein. Fastest onset. MAs do not typically initiate IV access in most states, but may monitor infusions or perform IV draws where scope of practice permits.
Controlled Substances and DEA Schedules
The Drug Enforcement Administration classifies controlled substances into five schedules based on accepted medical use and potential for abuse or dependence.
| Schedule | Criteria | Examples |
|---|---|---|
| Schedule I | No accepted medical use, high abuse potential | Heroin, LSD, marijuana (federal) |
| Schedule II | High abuse potential, may cause severe dependence | Oxycodone, fentanyl, Adderall, morphine, cocaine |
| Schedule III | Moderate to low physical dependence | Codeine combinations, testosterone, ketamine |
| Schedule IV | Lower abuse potential than III | Benzodiazepines, zolpidem, tramadol |
| Schedule V | Lowest abuse potential | Cough preps with small amounts of codeine, pregabalin |
In clinical practice, controlled substances require a DEA-registered provider to prescribe, a separate controlled substance log, and strict inventory counts. Discrepancies must be reported immediately. Never leave controlled substances unattended.
Prescription vs. OTC Medications
Prescription medications require a provider order and are dispensed through a licensed pharmacy. OTC medications are available without a prescription. Both can cause harm if given incorrectly. Patients often do not mention OTC medications when asked about their medications — always ask specifically about vitamins, supplements, and over-the-counter products during the medication reconciliation process.
Checking Expiration Dates
Always check the expiration date before administering any medication. An expired medication may be degraded, less effective, or in some cases harmful. This applies to vaccines, injectable medications, topical products, and oral medications equally. Pull expired medications from stock and follow your facility protocol for disposal. For vaccines, check both the vial and the diluent if reconstitution is required.
Documentation Requirements
Every medication administered must be documented. At minimum, record:
- Date and time of administration
- Name of the medication (generic or brand per facility policy)
- Dose given
- Route and site (for injections, specify exact location)
- Patient response or any adverse effects noted
- Administering clinician's name and credentials
If a medication is not given — patient refused, patient was away, medication was unavailable — document it as a missed dose with the reason. Do not chart a medication as given until you have actually given it. Late entries must be clearly labeled as such.
Good documentation protects the patient and protects you. In any legal or regulatory review, if it is not documented, it did not happen.
