BIOD 150 Medical Terminology Midterm Exam Practice
Questions and Detailed Solutions Latest Update 2026/2027 |
Prefixes, Suffixes, Medical Abbreviations, Verified Answers -
190 Questions
This rigorous midterm examination assesses advanced mastery of medical terminology, including prefixes,
suffixes, root words, and medical abbreviations, with emphasis on application in clinical contexts, interpretation
of complex terms, and synthesis across body systems. Questions demand deep reasoning, recognition of subtle
distinctions, and integration of terminology with physiological and pathological concepts. It contains 190
multiple-choice questions, each with four distractors and a fully worked rationale that explains why the keyed
answer is correct. Questions are organized into clearly labelled sections that mirror the major content areas of
the course. Targeted learning outcomes include: Apply knowledge of prefixes, suffixes, and roots to decode and
construct complex medical terms.; Interpret medical abbreviations and their context-dependent meanings in
clinical documentation.; Analyze the etymological basis of medical terminology to infer meanings in novel
scenarios.; Evaluate the impact of terminology on clinical communication and patient safety.. Every item has been
reviewed for clinical accuracy, current guidelines, and clarity so that students can study with confidence and
self-correct as they work through the bank. Use it as a high-yield review immediately before the exam, or as a
structured practice tool during the unit - the rationales double as concise teaching notes. The recommended
writing time is 3 hours, with a passing score of 75%. Aligned with Aligned with standards of the American
Medical Association (AMA) and the Accreditation Council for Continuing Medical Education (ACCME),
Section 1: General (Questions 1-190)
1 A patient with chronic kidney disease is noted to have an elevated
BUN and creatinine. The term 'azotemia' is derived from which
combination of roots and suffixes, and what does it precisely
indicate?
A) Azot/o (nitrogen) + -emia (blood condition); indicates excess
nitrogenous waste in the blood.
B) Azo (without) + -temia (tissue); indicates absence of tissue
oxygenation.
C) Azot/o (urea) + -emia (urine); indicates urea in the urine.
D) Azo (nitrogen) + -emia (blood); indicates low blood nitrogen
levels.
Answer: A
Rationale: Azotemia is formed from 'azot/o' (nitrogen) and '-emia'
(blood condition), meaning excess nitrogenous waste in blood. Option
B misinterprets 'azo' as 'without' and '-temia' as tissue. Option C
incorrectly assigns 'azot/o' to urea and '-emia' to urine. Option D
,reverses the meaning to low nitrogen.
2 In the term 'cholecystectomy', what is the correct segmentation and
meaning of each component?
A) chole (bile) + cyst (bladder) + ectomy (surgical removal);
removal of the gallbladder.
B) chol (bile) + ecyst (bladder) + ectomy (incision); incision into the
bile duct.
C) chole (gall) + cyst (sac) + ectomy (repair); repair of a sac.
D) chole (bile) + cyst (bladder) + otomy (surgical removal); removal
of a bladder stone.
Answer: A
Rationale: Cholecystectomy is correctly segmented as chole (bile) +
cyst (bladder) + ectomy (surgical removal), meaning surgical removal
of the gallbladder. Option B incorrectly uses 'ectomy' as incision.
Option C misidentifies 'ectomy' as repair. Option D uses 'otomy'
incorrectly for removal.
3 A physician notes 'tachycardia' and 'bradypnea' in a patient's chart.
How do these two terms differ in their prefixes and what
physiological systems do they describe?
A) Tachy- (fast) describes heart rate; brady- (slow) describes
respiratory rate.
B) Tachy- (slow) describes heart rate; brady- (fast) describes
respiratory rate.
C) Both describe heart rate; tachy- means fast, brady- means slow.
D) Both describe respiratory rate; tachy- means slow, brady- means
fast.
Answer: A
Rationale: Tachycardia uses tachy- (fast) and -cardia (heart), indicating
rapid heart rate. Bradypnea uses brady- (slow) and -pnea (breathing),
indicating slow respiratory rate. Option B swaps the meanings. Option
C and D incorrectly assign both to the same system.
,4 Which of the following medical abbreviations is correctly matched
with its meaning and is considered a high-alert abbreviation by The
Joint Commission?
A) Q.D. - every day; should be written as 'daily' to avoid confusion.
B) U - unit; acceptable in all contexts.
C) HS - at bedtime; no risk of misinterpretation.
D) IM - intramuscular; no risk of misinterpretation.
Answer: A
Rationale: Q.D. is a high-alert abbreviation on The Joint Commission's
'Do Not Use' list due to risk of being mistaken for QID or OD; it
should be written as 'daily'. U is also on the list but is not acceptable.
HS and IM are not on the list but can still cause confusion, yet they
are not high-alert in the same way. Option A correctly identifies Q.D.
as high-alert and the need to write 'daily'.
5 A patient's chart includes 'SOB', 'DOE', and 'orthopnea'. Which
statement best integrates these abbreviations and terms to describe
the patient's condition?
A) The patient experiences shortness of breath on exertion and
requires multiple pillows to breathe, indicating possible heart failure.
B) The patient has no breathing issues; these terms are unrelated.
C) The patient has a pulmonary embolism causing sudden onset of
breathlessness.
D) The patient has chronic bronchitis with wheezing and cough.
Answer: A
Rationale: SOB (shortness of breath), DOE (dyspnea on exertion), and
orthopnea (difficulty breathing when lying flat) collectively suggest
cardiac or pulmonary pathology, commonly heart failure. Option B is
incorrect as they are all respiratory symptoms. Option C and D are
specific diagnoses not necessarily indicated by these terms alone.
6 In the term 'epidural', the prefix 'epi-' means 'upon' or 'above'. Which
of the following terms uses the same prefix with a similar meaning?
, A) Epigastric - above the stomach.
B) Endocardial - within the heart.
C) Subcutaneous - below the skin.
D) Transdermal - across the skin.
Answer: A
Rationale: Epidural uses 'epi-' meaning above or upon, referring to the
space above the dura mater. Epigastric similarly uses 'epi-' meaning
above the stomach. Endocardial uses 'endo-' (within), subcutaneous
uses 'sub-' (below), and transdermal uses 'trans-' (across).
7 A patient is diagnosed with 'hyperglycemia' and 'hypokalemia'.
What is the combined meaning of these two conditions?
A) High blood sugar and low blood potassium.
B) Low blood sugar and high blood potassium.
C) High blood sugar and high blood potassium.
D) Low blood sugar and low blood potassium.
Answer: A
Rationale: Hyperglycemia: hyper- (high) + glyc/o (sugar) + -emia
(blood) = high blood sugar. Hypokalemia: hypo- (low) + kal/i
(potassium) + -emia (blood) = low blood potassium. Option A
correctly identifies both.
8 The abbreviation 'NPO' is derived from the Latin 'nil per os'. In a
clinical setting, what does 'NPO after midnight' mean for a patient
scheduled for surgery?
A) The patient must not eat or drink anything after midnight.
B) The patient may have clear liquids until morning.
C) The patient should take only essential medications with water.
D) The patient must fast from solid foods but may have water.
Answer: A
Rationale: NPO means nothing by mouth, so 'NPO after midnight'
strictly prohibits any oral intake, including water, to reduce aspiration
risk during anesthesia. Option B, C, and D are incorrect as they allow
