NCMA Pharmacology and Medication Administration 2 — Questions and Answers
Question 1: What are the 'Ten Rights' of medication administration that have expanded from the original 'Five Rights'?
- Right patient, right medication, right dose, right route, right time, right documentation, right reason, right response, right to refuse, right education (Correct answer)
- Right patient, right medication, right dose, right route, right time only
- Right patient, right dose, right insurance, right doctor, right nurse
- Right medication, right time, right cost, right pharmacy, right diagnosis
Correct answer: Right patient, right medication, right dose, right route, right time, right documentation, right reason, right response, right to refuse, right education
The Ten Rights of medication administration expand the classic Five Rights (patient, drug, dose, route, time) to include documentation, reason (indication), response (outcome assessment), right to refuse, and patient education — forming a comprehensive safety framework.
The expansion reflects modern patient safety standards: Right documentation requires timely, accurate recording of every administered dose. Right reason means verifying the drug is indicated for the patient's condition. Right response means assessing the patient after administration to confirm therapeutic effect and detect adverse reactions. Right to refuse must be documented and the provider notified. Right education means the patient understands the medication purpose, dosing, and side effects. Applying all ten rights reduces medication errors, which are a leading cause of preventable patient harm.
Question 2: What is the difference between a drug's generic name and its trade (brand) name?
- The generic name is the non-proprietary chemical/pharmacological name (same worldwide); the trade name is the manufacturer-specific proprietary name given to a specific formulation (Correct answer)
- The trade name is the chemical formula; the generic name is the brand
- Generic drugs are always of lower quality than trade-name drugs
- Trade names are assigned by the FDA; generic names are assigned by manufacturers
Correct answer: The generic name is the non-proprietary chemical/pharmacological name (same worldwide); the trade name is the manufacturer-specific proprietary name given to a specific formulation
The generic name (e.g., ibuprofen) is the official chemical name of the active ingredient, standardized internationally; the trade name (e.g., Advil, Motrin) is a proprietary name given by the manufacturer to their specific formulation.
After a drug's patent expires (typically 20 years from filing), other manufacturers may produce generic versions containing the same active ingredient, strength, dosage form, and route of administration as the original brand. Generic drugs are bioequivalent to brand-name drugs and are FDA-approved. In medical documentation, medications should be recorded using their generic names for clarity and universality. However, some medications have narrow therapeutic windows (e.g., levothyroxine, warfarin) where brand-to-generic substitution requires monitoring.
Question 3: Which medication schedule under the Controlled Substances Act (CSA) has the HIGHEST potential for abuse with no accepted medical use in the United States?
- Schedule I (e.g., heroin, LSD, psilocybin) (Correct answer)
- Schedule II (e.g., oxycodone, fentanyl, methamphetamine)
- Schedule III (e.g., buprenorphine, anabolic steroids)
- Schedule IV (e.g., benzodiazepines, zolpidem)
Correct answer: Schedule I (e.g., heroin, LSD, psilocybin)
Schedule I substances have the highest abuse potential, no currently accepted medical use in treatment in the US, and lack accepted safety even under medical supervision — making them illegal for clinical use (examples: heroin, LSD, marijuana federally, MDMA).
DEA schedules: Schedule I (no medical use, high abuse — heroin, LSD), Schedule II (high abuse, severe dependence, accepted medical use with severe restrictions — morphine, oxycodone, fentanyl, amphetamine, cocaine), Schedule III (less abuse potential than II, moderate dependence — anabolic steroids, buprenorphine), Schedule IV (lower abuse potential — benzodiazepines, tramadol, zolpidem), Schedule V (lowest — cough preparations with codeine, pregabalin). Medical assistants must understand scheduling for documentation, storage (locked cabinets for II–V), disposal, and legally compliant record-keeping.
Question 4: What is the purpose of an allergy check before administering any medication?
- To identify documented allergic reactions or intolerances that could cause anaphylaxis or significant adverse reactions to the medication or its components (Correct answer)
- To determine the correct dose for the patient's weight
- To verify the prescription was written by an authorized provider
- To confirm the patient's insurance will cover the medication
Correct answer: To identify documented allergic reactions or intolerances that could cause anaphylaxis or significant adverse reactions to the medication or its components
Allergy verification prevents administration of a medication (or a cross-reactive medication) to which a patient has had a documented allergic or adverse reaction; anaphylaxis, a life-threatening reaction, can result from failure to check allergies.
Before any medication administration: check the allergy list in the EHR for the specific drug and drug class. Cross-reactivity examples: penicillin allergy may predict reaction to some cephalosporins (3–5% cross-reactivity); sulfonamide allergy may predict reactions to other sulfa drugs. Document the allergy reaction type (hives, anaphylaxis, GI upset, rash) to distinguish true allergies from intolerances. If a patient reports a new allergy, update the record before proceeding. When uncertain, consult the provider or pharmacist before administering.
Question 5: What is the correct technique for drawing up a medication from a single-dose vial?
- Clean the rubber stopper with alcohol and allow to dry, draw air equal to the desired dose into the syringe, inject air into the vial, withdraw the medication, and verify the dose before administration (Correct answer)
- Pierce the vial without cleaning, withdraw medication immediately
- Shake the vial vigorously before drawing up
- Use the same syringe for multiple patients if the vial is large enough
Correct answer: Clean the rubber stopper with alcohol and allow to dry, draw air equal to the desired dose into the syringe, inject air into the vial, withdraw the medication, and verify the dose before administration
Drawing up from a vial requires: alcohol prep of the stopper, injecting air equal to the desired volume (creates positive pressure for easier withdrawal), inverting the vial, withdrawing the medication, and checking the dose for accuracy — maintaining sterile technique throughout.
Injecting air equal to the withdrawal volume prevents a negative pressure vacuum that makes withdrawal difficult. After inversion, the needle tip should be submerged to avoid drawing air. Tap the syringe barrel to dislodge air bubbles and expel them before injection. Never recap needles after use — immediately discard into a sharps container. Single-dose vials (SDVs) should never be used for more than one patient even if medication remains; multi-dose vials (MDVs) must be dated when opened (28-day in-use date per CDC) and stored per manufacturer instructions.
Question 6: A patient is prescribed an intramuscular (IM) injection. Which site is the PREFERRED site for IM injections in adults?
- Deltoid or ventrogluteal (preferred for large-volume or irritating medications) (Correct answer)
- Dorsal gluteal (dorsogluteal) site in the upper outer buttock quadrant
- Antecubital fossa (inner elbow)
- Dorsal surface of the hand
Correct answer: Deltoid or ventrogluteal (preferred for large-volume or irritating medications)
The deltoid (for small volumes, up to 1 mL) and ventrogluteal sites are currently preferred for IM injections in adults; the ventrogluteal site (lateral hip) is the safest for large volumes (up to 5 mL) because it is free of major nerves and blood vessels.
The dorsogluteal site (upper outer quadrant of the buttock) was traditionally used but is now discouraged because of proximity to the sciatic nerve and superior gluteal artery, risk of inadvertent subcutaneous injection due to fat thickness, and patient positioning difficulties. The ventrogluteal site (landmark: place palm on greater trochanter, index finger on anterior superior iliac spine, spread middle finger posteriorly — inject in the V) is the safest due to thick muscle mass and absence of major neurovascular structures. Deltoid accepts up to 1 mL; vastus lateralis in the thigh accepts 1–3 mL and is preferred for pediatric injections.
