SECTION I — TERMINOLOGY, ABBREVIATIONS, CLASSIFICATIONS & Comprehensive
SAFETY Review
1. The medical terminology suffix "-algia" means:
A. Inflammation
B. Pain
C. Swelling
D. Infection
CORRECT ANSWER B — Pain. The suffix "-algia" indicates pain (e.g., neuralgia = nerve pain, myalgia = muscle pain,
arthralgia = joint pain).
RATIONALE Common medical suffixes: -algia (pain), -itis (inflammation), -osis (condition), -ectomy (surgical removal), -
otomy (cutting into), -ostomy (creating an opening). Understanding these suffixes helps medication aides
interpret medical terms and understand medication indications and side effects.
, 2. The prefix "hyper-" means:
A. Low; below normal
B. High; above normal
C. Without
D. Against
CORRECT ANSWER B — High; above normal. Hyper- indicates elevation (hyperglycemia = high blood sugar, hypertension =
high blood pressure, hyperthermia = elevated body temperature).
RATIONALE Hyper- (high) vs. Hypo- (low): This distinction is critical for understanding medication effects and side effects.
Hyperglycemia = blood sugar too high (may need insulin). Hypoglycemia = blood sugar too low (may need
glucose). Hyperthyroidism = overactive thyroid. Hypothyroidism = underactive thyroid (treated with
levothyroxine).
3. The abbreviation "OD" means:
A. Both eyes
B. Left eye
C. Right eye
D. Once daily
CORRECT ANSWER C — Right eye. OD (oculus dexter) = right eye; OS (oculus sinister) = left eye; OU (oculus uterque) = both
eyes.
RATIONALE IMPORTANT SAFETY NOTE: OD, OS, OU, and QD are on The Joint Commission's "Do Not Use" abbreviation list
because they are easily misread and can cause medication errors. However, medication aides must recognize
these abbreviations on existing orders and verify with the nurse before administration. Modern practice uses
"right eye," "left eye," "both eyes," and "daily" written out.
4. The abbreviation "bid" means:
A. Once daily
B. Two times a day
C. Three times a day
D. Four times a day
CORRECT ANSWER B — Two times a day. bid (bis in die) = twice daily; tid (ter in die) = three times daily; qid (quater in die)
= four times daily.
RATIONALE Frequency abbreviations: qd = every day (daily), bid = twice daily, tid = three times daily, qid = four times
daily, qod = every other day, q_h = every _ hours (q4h, q6h, q8h), PRN = as needed, STAT = immediately. These
abbreviations are essential for reading MARs and administering medications at the correct times.
5. The abbreviation "hs" means:
A. After meals
B. Before meals
C. Hour of sleep; bedtime
D. Every hour
CORRECT ANSWER C — Hour of sleep; bedtime. hs (hora somni) indicates medication should be given at bedtime.
RATIONALE Timing abbreviations: ac = before meals (ante cibum), pc = after meals (post cibum), hs = at bedtime, AM =
morning, PM = afternoon/evening. Bedtime medications (sedatives, some antihypertensives, statins) are
timed for therapeutic effect and to minimize daytime side effects like drowsiness.
