SECTION I — MEDICAL ABBREVIATIONS & MEASUREMENT CONVERSIONS Questions 1 – 55
1. What does the abbreviation AD stand for?
A. Left ear
B. Right ear (auris dextra)
C. Both ears
D. As directed
CORRECT ANSWER B — AD (auris dextra) = RIGHT EAR
RATIONALE AD = auris dextra (Latin for right ear). The medication aide must know these abbreviations to correctly administer otic (ear) medications to the correct side. AS (auris sinistra) = left ear. AU
(auris uterque) = both ears. Similarly for eyes: OD (oculus dexter) = right eye; OS (oculus sinister) = left eye; OU (oculus uterque) = both eyes. Confusing these abbreviations can result in
administering medication to the wrong ear or eye — a medication error. Always verify the MAR order against the abbreviation before administration.
2. What does the abbreviation AS stand for?
A. Right ear
B. Left ear (auris sinistra)
C. Both eyes
D. As soon as possible
CORRECT ANSWER B — AS (auris sinistra) = LEFT EAR
RATIONALE AS = auris sinistra (Latin for left ear). AD = right ear, AU = both ears. These otic abbreviations are critical for safe administration of ear drops. The medication aide must distinguish AS (left ear)
from OS (left eye) — one letter difference, completely different administration site. Always double-check the MAR and the medication label against these abbreviations. Ear drops and eye
drops are NOT interchangeable — using ear drops in the eye can cause corneal damage.
3. What does the abbreviation AU stand for?
A. Right eye
B. Left ear
C. Both ears (auris uterque)
D. As needed
CORRECT ANSWER C — AU (auris uterque) = BOTH EARS
RATIONALE AU = auris uterque (Latin for both ears). This abbreviation indicates the medication is to be administered to BOTH ears. This differs from OU (oculus uterque) which means both eyes. The
medication aide must carefully distinguish between ear (otic) and eye (ophthalmic) abbreviations. Otic preparations are formulated specifically for the ear and should never be used in the
eyes.
4. What does the abbreviation ac mean?
A. After meals
B. Before meals (ante cibum)
C. At bedtime
D. As needed
CORRECT ANSWER B — ac (ante cibum) = BEFORE MEALS
RATIONALE ac = ante cibum (Latin for before meals). This abbreviation indicates the medication should be administered before the patient eats. Examples: insulin is often given ac to coordinate with
meal intake; some medications require an empty stomach for absorption. The opposite is pc (post cibum) = after meals. The medication aide must time ac medications appropriately —
typically 30 minutes before the meal. Understanding these timing abbreviations ensures medications work as intended and minimizes GI side effects.
5. What does bid mean?
A. Three times a day
B. Twice a day (bis in die)
C. Four times a day
D. Every other day
CORRECT ANSWER B — bid (bis in die) = TWICE A DAY
RATIONALE bid = bis in die (Latin for twice a day). Standard dosing frequency abbreviations: qd (every day), bid (twice daily), tid (three times daily), qid (four times daily), qod (every other day). The
medication aide must space bid doses appropriately — typically 12 hours apart (e.g., 8 AM and 8 PM) unless otherwise specified. These abbreviations are among the most commonly used in
medication orders and must be memorized. Some facilities discourage these abbreviations (per Joint Commission "Do Not Use" list) in favor of writing out the full instruction.
, 6. What does cc stand for and what is it equivalent to?
A. Cubic centimeter; equivalent to 1 milliliter (mL)
B. Cubic centimeter; different volume than mL
C. Capsule count
D. Continuous care
CORRECT ANSWER A — cc = cubic centimeter; 1 cc = 1 mL (same volume); TRUE: milliliter and cubic centimeter are equivalent
RATIONALE Cubic centimeter (cc) and milliliter (mL) are the SAME volume measurement — they are interchangeable (1 cc = 1 mL). This is a fundamental conversion the medication aide must know. The
preferred unit for dispensing liquid medications is the milliliter (mL) or cubic centimeter (cc). However, milliliter (mL) and milligram (mg) are NOT the same — mL measures VOLUME, mg
measures WEIGHT/MASS. This distinction is critical: 1 mL of a medication does NOT necessarily equal 1 mg (the relationship depends on the drug's concentration). Confusing mL and mg can
cause serious dosing errors.
7. What does the abbreviation gtt mean?
A. Gram
B. Drop (gutta)
C. Grain
D. Gelatin
CORRECT ANSWER B — gtt (gutta) = DROP; used for liquid medication dosing, especially eye and ear drops
RATIONALE gtt is the abbreviation for drop (from Latin "gutta"). It is commonly used in ophthalmic and otic medication orders (e.g., "2 gtt OU" = 2 drops in both eyes). The medication aide must
understand that a "drop" refers to a standardized pharmaceutical drop from a calibrated dropper, not a random drip. The size of a drop varies depending on the dropper tip and the liquid's
viscosity — always use the dropper provided with the medication. Do not interchange droppers between different medications.
8. What does HS or hs mean?
A. Half strength
B. Hour of sleep (bedtime) — hora somni
C. High sodium
D. Heparin solution
CORRECT ANSWER B — HS (hora somni) = HOUR OF SLEEP / BEDTIME
RATIONALE HS = hora somni (Latin for "at the hour of sleep" or bedtime). This abbreviation indicates the medication should be administered when the patient goes to bed for the night. It is commonly
used for sedatives/hypnotics, certain blood pressure medications, and medications that cause drowsiness. The medication aide should verify the facility's definition of "bedtime" (typically 9
PM or 10 PM) and administer HS medications at the appropriate time. Because HS can be confused with "half strength," some facilities include it on the "Do Not Use" abbreviation list — the
medication aide should know their facility's policy.
9. What does NPO mean?
A. No pain observed
B. Nothing by mouth (nil per os)
C. No parenteral orders
D. Nasal pharyngeal obstruction
CORRECT ANSWER B — NPO (nil per os) = NOTHING BY MOUTH; patient cannot take any oral intake
RATIONALE NPO means the patient is to receive NOTHING by mouth — no food, no fluids, and no oral medications. This order is typically given before surgery, procedures, or when the GI tract needs
rest. When a patient is NPO, the medication aide must: (1) HOLD all oral medications. (2) Notify the RN or provider — alternative routes (IV, rectal, sublingual) may be needed. (3) Document
the held medications and the reason. Never give oral medications to an NPO patient without explicit clarification from the RN or provider. This is a critical patient safety issue — violating
NPO status can cause aspiration during anesthesia or worsen GI conditions.
10. What does SL stand for?
A. Slightly
B. Sublingual — under the tongue
C. Sodium level
D. Suspension liquid
CORRECT ANSWER B — SL = SUBLINGUAL (under the tongue); medication placed under the tongue for rapid absorption
RATIONALE SL = sublingual. The medication is placed UNDER the tongue where it dissolves and is rapidly absorbed through the sublingual mucosa directly into the bloodstream, bypassing first-pass
liver metabolism. Classic example: nitroglycerin for chest pain. The medication aide must: (1) Instruct the patient NOT to swallow — the medication must dissolve completely under the
tongue. (2) Ensure the patient does not eat, drink, or smoke until the medication is fully dissolved. (3) Document the administration and monitor for therapeutic effect. Sublingual is one of
three oral cavity routes: oral (swallowed), sublingual (under tongue), and buccal (inside cheek).
11. What does STAT mean?
A. Standard treatment
B. Immediately — without any delay (statim)
C. Situation to assess tomorrow
D. Standing order
CORRECT ANSWER B — STAT (statim) = IMMEDIATELY; medication must be given at once without any delay
RATIONALE STAT orders are the HIGHEST PRIORITY — the medication must be administered immediately. STAT orders are used for emergency situations: severe pain, acute respiratory distress,
anaphylaxis, cardiac emergencies. When a STAT order is received, the medication aide must: (1) Stop current tasks and prepare the medication immediately. (2) Administer as quickly as
safely possible. (3) Document the exact time of administration. (4) Monitor the patient closely for response. STAT differs from ASAP (as soon as possible) — STAT is immediate; ASAP allows
for prioritization within a short timeframe. STAT orders cannot wait for routine medication pass times.
12. What does ADR stand for?
A. As directed regularly
B. Adverse Drug Reaction — an unintended, harmful reaction to a medication
C. After dinner routine
D. Administration documentation record
CORRECT ANSWER B — ADR = ADVERSE DRUG REACTION; an unintended, harmful reaction to a medication at normal doses
RATIONALE An Adverse Drug Reaction (ADR) is any noxious, unintended, and undesired effect of a medication that occurs at doses used for prevention, diagnosis, or treatment. ADRs range from mild
(rash, nausea) to severe (anaphylaxis, Stevens-Johnson syndrome, organ failure). The medication aide's role: (1) Recognize potential ADRs (allergic reactions, side effects, toxic effects). (2)
Report any suspected ADR to the RN immediately. (3) Document the reaction in the patient's record. (4) Ensure allergy information is prominently displayed (allergy band, MAR). ADRs are
distinct from side effects (predictable, often unavoidable) and medication errors (preventable).
