EXAMINATION INSTRUCTIONS
▸ Select the single best answer for each multiple-choice question.

▸ Correct answers and detailed rationales appear below each question for state certification exam review purposes.
SECTION I — ABBREVIATIONS, TERMINOLOGY & MEDICATION ADMINISTRATION BASICS Questions 1 – 12
1. The abbreviation "S/E" in medication documentation stands for:
A. Standard Error
B. SIDE EFFECTS — unintended secondary effects of a medication
C. Sublingual Equivalent
D. Systemic Evaluation
CORRECT ANSWER B — S/E = Side Effects; predictable, often unavoidable secondary effects of medications at therapeutic doses
RATIONALE Side effects are distinct from adverse reactions (unpredictable, harmful) and toxic effects (from overdose/accumulation). The medication aide must
document and report side effects to the nurse. Common side effects: diuretics → excessive K⁺ loss; antihistamines → drowsiness; opioids →
constipation. S/S means Signs and Symptoms. Understanding abbreviations is essential for reading MARs and medication orders. Always document
using approved abbreviations only.
2. What does the abbreviation "OS" mean in medication administration?
A. Right eye (OD)
B. LEFT EYE (oculus sinister)
C. Both eyes (OU)
D. Right ear (AD)
CORRECT ANSWER B — OS = Oculus Sinister (LEFT EYE). OD = Right Eye; OU = Both Eyes; AD = Right Ear; AS = Left Ear; AU = Both Ears
RATIONALE Ophthalmic abbreviations: OD (oculus dexter) = right eye. OS (oculus sinister) = left eye. OU (oculus uterque) = both eyes. These must NOT be
confused with otic (ear) abbreviations: AD (auris dextra) = right ear, AS (auris sinistra) = left ear, AU (auris uterque) = both ears. One letter difference
can result in administering eye drops in the ear or vice versa — a serious medication error. Always verify the route and the abbreviation before
administration.
3. The abbreviation "AC" in medication orders means:
A. After meals (PC)
B. BEFORE MEALS (ante cibum) — medication should be given before the patient eats
C. At bedtime (HS)
D. As needed (PRN)
CORRECT ANSWER B — AC = Ante Cibum (BEFORE MEALS). PC = Post Cibum (AFTER MEALS). BID = Twice a Day
RATIONALE AC medications should be given approximately 30 minutes before meals. PC medications are given after meals. Common timing abbreviations: BID
(twice daily), TID (three times daily), QID (four times daily), HS (hour of sleep/bedtime), PRN (as needed), STAT (immediately). The medication aide
must time AC/PC medications appropriately — some require an empty stomach (AC), others are given with food to prevent GI upset (PC). ASA
(aspirin) should be given PC/with food to prevent gastric irritation.
, 4. How many times should the medication aide check the drug label during a medication pass?
A. Once — at the bedside
B. Twice — when pulling and when administering
C. THREE TIMES — when pulling from the cart, when checking the medication, and when returning to the med cart (or before administering)
D. Four times
CORRECT ANSWER C — Three checks: (1) When removing from storage, (2) When preparing/pouring, (3) Before administering/returning to cart
RATIONALE The three medication checks are the core safety protocol: (1) First check — when pulling from the medication cart/drawer, compare label to MAR. (2)
Second check — when preparing the medication (opening/pouring), verify label against MAR again. (3) Third check — at the bedside before
administration (or when returning the container to storage). Each check verifies: right patient, right medication, right dose, right route, right time.
These redundant checks are designed to catch errors before they reach the patient. Never skip a check.
5. Are medication aides responsible for their own actions?
A. No — the supervising nurse is always responsible
B. YES — medication aides are legally accountable for their own actions and must work within their scope of practice
C. Only during medication errors
D. Only when the nurse is not present
CORRECT ANSWER B — Yes; medication aides are legally responsible for their own actions and must follow all safety protocols
RATIONALE Every healthcare worker is accountable for their own actions under the law. The medication aide must: (1) Work within their scope of practice (oral,
topical, inhalation routes only). (2) Follow the six rights of medication administration. (3) Perform the three medication checks. (4) Document
accurately after administration. (5) Report errors immediately. Insulin injections are administered by LPN or RN — NOT medication aides. When in
doubt, ASK. If something doesn't seem clear, STOP and consult the nurse. "I was told to do it" is not a legal defense.
6. What does "K⁺" represent and what is an important nursing consideration when administering it?
A. Calcium — give on an empty stomach
B. POTASSIUM — should be given WITH MEALS to prevent gastric irritation
C. Sodium — give at bedtime
D. Chloride — give with milk
CORRECT ANSWER B — K⁺ = Potassium; give WITH MEALS to prevent gastrointestinal (GI) irritation and upset
RATIONALE Potassium (K⁺) supplements (e.g., Slow-K, K-Dur) are irritating to the gastric mucosa and should ALWAYS be given with food or a full glass of water.
Other electrolytes: Na⁺ = Sodium, Ca²⁺ = Calcium. Diuretics (especially loop and thiazide) cause excessive K⁺ loss (hypokalemia), requiring
monitoring and supplementation. Hypokalemia (K⁺ <3.5 mEq/L): muscle weakness, cardiac arrhythmias, U waves on EKG. Hyperkalemia (K⁺ >5.0
mEq/L): peaked T waves, cardiac arrest risk. The prefix "hypo-" means too little; "hyper-" means too much.
7. Before administering Lanoxin (digoxin), the medication aide must check which vital sign and ensure it meets what parameter?
A. Temperature — must be below 100.4°F
B. APICAL PULSE — must be GREATER THAN 60 beats per minute; hold if below 60 and notify nurse
C. Respiratory rate — must be above 12 per minute
D. Blood pressure — must be below 140/90
CORRECT ANSWER B — Apical pulse must be >60 bpm; Lanoxin (digoxin) slows and strengthens the heartbeat; hold if pulse <60
RATIONALE Lanoxin (digoxin) is a cardiac glycoside that increases cardiac contractility and slows heart rate. Before EVERY dose, the medication aide MUST: (1)
Measure APICAL pulse for a full 60 seconds. (2) Hold if pulse <60 bpm and notify the RN. (3) Document the pulse rate. Signs of digoxin toxicity: slow
heart beat (bradycardia), nausea, weakness, and HALO VISION (yellow-green visual disturbances). Digoxin has a narrow therapeutic index — the
margin between therapeutic and toxic levels is small. The apical pulse must be recorded on the MAR before administration.
8. When should an antacid be administered in relation to other medications?
A. At the same time as other medications — it doesn't matter
B. NOT at the same time as other medications — antacids interfere with absorption of many drugs
C. Immediately after other medications
D. Only at bedtime
CORRECT ANSWER B — Antacids should NOT be given at the same time as other medications; they alter gastric pH and bind to drugs, reducing absorption
RATIONALE Antacids (Mylanta, Maalox, Tums) neutralize stomach acid and can: (1) Bind to other medications in the GI tract, preventing absorption. (2) Alter
gastric pH, affecting dissolution of pH-dependent drugs. (3) Chelate certain drugs (tetracyclines, fluoroquinolones). Separate antacids from other
oral medications by at least 1-2 hours. Mylanta neutralizes stomach acid. Iron supplements should not be given within 1 hour of antacids or milk
products. The medication aide must schedule medication passes to avoid these interactions.
9. A rectal suppository should be inserted how far in an adult?
A. 1 inch
B. 2 inches — same as for children
C. 4 INCHES for adults; 2 INCHES for children
D. 6 inches
CORRECT ANSWER C — Adults: 4 inches. Children: 2 inches. This ensures the suppository is placed past the internal anal sphincter
RATIONALE Rectal suppositories must be inserted past the internal anal sphincter to be retained and absorbed. Adults: approximately 4 inches (10 cm).
Children: approximately 2 inches (5 cm). Technique: (1) Position client in left Sims' position. (2) Lubricate the suppository tip. (3) Insert with gloved
finger, directing toward the umbilicus. (4) Instruct client to retain for 15-30 minutes. (5) Document administration. Suppositories melt at body
temperature and are absorbed through the rectal mucosa, partially bypassing first-pass liver metabolism.
