RMA Pharmacology and Medication Administration 2 — Questions and Answers
Question 1: Which of the 'Six Rights' of medication administration specifies that the medical assistant must verify the medication is being given at the appropriate time?
- Right patient
- Right drug
- Right time (Correct answer)
- Right route
Correct answer: Right time
The 'Right Time' right requires verifying that the medication is administered at the correct scheduled time and frequency — important for maintaining therapeutic drug levels and treatment efficacy.
The Six Rights (or Ten Rights in expanded versions) of medication administration are a foundational safety framework. The traditional Six Rights are: Right Patient (confirm identity with two identifiers), Right Drug (verify drug name against the order — no substitutions without authorization), Right Dose (verify the ordered dose and calculate if needed), Right Route (verify how the drug should be administered — oral, IM, IV, topical), Right Time (verify the scheduled time and frequency), Right Documentation (record the drug, dose, route, time, and patient response after administration). Right Time is critical for several reasons: some medications must be taken with meals or on an empty stomach to optimize absorption; certain drugs require strictly maintained serum levels (antibiotics, anticoagulants, antiepileptics); other drugs are scheduled to minimize side effects (e.g., diuretics in the morning to avoid nocturia); insulin must be timed with meals to prevent hypoglycemia. Expanded versions add: Right Reason (clinical indication is appropriate), Right Form (tablet vs. liquid as ordered), Right Response (patient was monitored for expected and adverse effects), Right to Refuse (patient's right), and Right Assessment (checking relevant parameters before giving, like BP before antihypertensives).
Question 2: A physician orders 'metformin 500 mg PO BID with meals.' What does 'BID' mean?
- Once daily
- Twice daily (Correct answer)
- Three times daily
- Four times daily
Correct answer: Twice daily
BID is the Latin abbreviation for 'bis in die,' meaning twice daily; the patient takes metformin 500 mg with breakfast and again with dinner or the two largest meals.
Latin prescription abbreviations are still widely used in medical practice. Frequency abbreviations: QD (quaque die) = once daily; BID (bis in die) = twice daily; TID (ter in die) = three times daily; QID (quater in die) = four times daily; Q8H = every 8 hours; Q12H = every 12 hours; PRN (pro re nata) = as needed; AC (ante cibum) = before meals; PC (post cibum) = after meals; QHS (quaque hora somni) = at bedtime; STAT = immediately. Route abbreviations: PO (per os) = by mouth/oral; IM = intramuscular; IV = intravenous; SQ/SC = subcutaneous; ID = intradermal; SL = sublingual; TOP = topical; NAS = nasal; AU = both ears; AS = left ear; AD = right ear; OU = both eyes; OS = left eye; OD = right eye. For metformin BID with meals: the patient would take one 500 mg tablet with the morning meal and one 500 mg tablet with the evening meal. Taking metformin with food reduces GI side effects (nausea, diarrhea). Medical assistants must correctly interpret and communicate prescription abbreviations to patients.
Question 3: When preparing an injection from a multi-dose vial, which action is essential to prevent contamination of the vial's contents?
- Wipe the rubber stopper with sterile water before insertion
- Inject air into the vial equal to the volume of medication to be withdrawn, then use aseptic technique throughout (Correct answer)
- Store the vial in the freezer between uses to kill microorganisms
- Use the same needle used to withdraw the medication to inject the patient
Correct answer: Inject air into the vial equal to the volume of medication to be withdrawn, then use aseptic technique throughout
Injecting air equal to the withdrawal volume creates positive pressure to ease withdrawal, and aseptic technique throughout — including wiping the stopper with 70% alcohol and using a new needle for each patient — prevents contamination of the vial.
Preparing medications from a multi-dose vial requires strict aseptic technique to prevent contamination: (1) Verify the vial — check the medication name, concentration, expiration date, and appearance; (2) Wipe the rubber stopper with a 70% isopropyl alcohol swab and allow to dry; (3) Inject air into the vial equal to the volume of medication to be withdrawn — this creates positive pressure inside the vial, making withdrawal easier and preventing vacuum formation that can introduce contaminants; (4) Withdraw the correct volume; (5) Remove the needle used to draw up the medication and replace with a new needle for injection (the drawing-up needle has penetrated the vial stopper and is no longer sharply pointed — dulled needles cause more pain and can introduce particles). Multi-dose vials can be contaminated through technique failures and should be stored per manufacturer recommendations (refrigerated if required), labeled with the date opened, and discarded within 28 days of opening per CDC guidelines (or per manufacturer, whichever is sooner). A vial that appears cloudy, discolored, or has particles should never be used. The same needle must never be used on more than one patient.
Question 4: Which of the following medications belongs to the Schedule II controlled substance category under the DEA Controlled Substances Act?
- Tramadol (Schedule IV)
- Oxycodone (Schedule II) (Correct answer)
- Benzodiazepines such as diazepam (Schedule IV)
- Codeine-containing cough syrup (Schedule V)
Correct answer: Oxycodone (Schedule II)
Oxycodone is a Schedule II controlled substance — it has a high potential for abuse and physical or psychological dependence, and can only be prescribed with a DEA registration and specific record-keeping requirements.
The DEA Controlled Substances Act (CSA) classifies drugs into five schedules based on their medical utility and potential for abuse and dependence: Schedule I: No accepted medical use, high abuse potential (heroin, LSD, marijuana in most federal contexts). Cannot be prescribed. Schedule II: High abuse potential, severe dependence risk, but accepted medical use with severe restrictions. Examples: oxycodone, morphine, fentanyl, hydromorphone, methadone, Adderall (amphetamine), Ritalin (methylphenidate), cocaine (medical use). Requires DEA registration, written (or electronic) prescription, no refills, 30-day supply maximum in most states. Schedule III: Moderate dependence potential. Examples: buprenorphine, anabolic steroids, testosterone. Up to 5 refills in 6 months. Schedule IV: Lower dependence potential. Examples: benzodiazepines (diazepam, alprazolam), tramadol, zolpidem. Up to 5 refills in 6 months. Schedule V: Lowest controlled potential. Examples: codeine combination cough syrups, pregabalin. May be dispensed in some states without prescription. Medical assistants who handle prescriptions must understand scheduling requirements and the special handling protocols for Schedule II substances.
Question 5: A patient's chart shows a medication order for 'aspirin 325 mg PO STAT.' Which of the following BEST describes what 'STAT' means?
- Standard dosing — give at the scheduled time
- Slow titration — increase the dose gradually
- Immediately — give without delay (Correct answer)
- Subcutaneous — give by injection under the skin
Correct answer: Immediately — give without delay
STAT (from Latin 'statim,' meaning immediately) indicates the medication must be administered right away without waiting for scheduled medication rounds, used for urgent clinical situations.
STAT is one of the most critical prescription abbreviations in clinical medicine. From the Latin 'statim' (immediately), STAT orders must be executed without delay — within minutes of receipt. In the clinical context, aspirin 325 mg STAT is commonly ordered for a patient with suspected acute myocardial infarction (MI) — the STAT designation means it should be chewed and swallowed immediately to provide antiplatelet effect as rapidly as possible. Other time-critical prescription abbreviations: ASAP (as soon as possible) — slightly less urgent than STAT but still prompt; NOW (or 'give once now') — similar to STAT in many facilities; PRN (pro re nata) — as needed when specific conditions are met. For STAT medications, the medical assistant must: recognize the urgency designation, retrieve and administer the medication immediately, confirm the patient has taken it, and document the time and outcome. In an acute cardiac event, every minute of delay in aspirin and emergency treatment increases myocardial cell death. STAT orders also require STAT documentation.
Question 6: Which of the following is the CORRECT action when a medical assistant accidentally draws up 2 mL of a medication instead of the ordered 1 mL dose?
- Inject the full 2 mL and document the correct ordered dose to avoid confusion
- Recap the needle and return the excess medication to the vial
- Discard the entire syringe and prepare a new syringe with the correct dose (Correct answer)
- Partially push the plunger to expel 1 mL before injecting the patient
Correct answer: Discard the entire syringe and prepare a new syringe with the correct dose
The correct action is to discard the improperly drawn syringe and start over, preparing a fresh syringe with the exact ordered dose — any manipulation of the filled syringe risks dose error or contamination.
Medication preparation errors must be corrected before administration, and the safest approach when an incorrect volume is drawn up is to discard the syringe entirely and prepare a new one with the correct dose. This is the recommended practice for several reasons: 1. Attempting to expel excess medication from a syringe (pushing the plunger to expel half) is imprecise — air bubbles, surface tension, and syringe calibration make it difficult to achieve exactly the correct volume this way. 2. Returning medication from a used syringe back into the vial is prohibited — the needle has been exposed to the external environment and could contaminate the multi-dose vial, risking infection in subsequent patients. 3. Administering the wrong dose and documenting otherwise constitutes fraud and endangers the patient. Safety culture in healthcare requires that no one should feel embarrassed about discarding a syringe and starting over — this is good practice, not wasteful. Controlled substances must be wasted in the presence of a witness who co-signs the waste documentation. Accurate dose preparation is a fundamental component of the Five/Six Rights of medication administration.
