Medical Abbreviations & Medical
Terminology | Practice Questions, Answers
& Exam Review 2027/2028
Practice Question Bank & Answer Rationale
THIS PACK CONTAINS
100 exam-style multiple-choice questions. Each question includes the correct answer and a complete
rationale for focused revision.
COVERAGE
This exam assesses advanced proficiency in medical abbreviations, symbols, and terminology across clinical,
diagnostic, and documentation contexts. It emphasizes error-prone abbreviations, current safety standards
(Joint Commission, ISMP), and accurate interpretation in patient care and health records.
STUDY GUIDE
Recommended duration: 2 hours. Passing target: 70%.

,1. A medication order reads 'MS 4 mg IV PRN q4h.' Which interpretation aligns with
current ISMP error-prone abbreviation standards?
[ ] A. Morphine sulfate 4 mg intravenous as needed every 4 hours
[ ] B. Magnesium sulfate 4 mg intravenous as needed every 4 hours
[ ] C. Morphine sulfate 4 mg intramuscular as needed every 4 hours
[ ] D. Meperidine sulfate 4 mg intravenous as needed every 4 hours
CORRECT: A. Morphine sulfate 4 mg intravenous as needed every 4 hours
ISMP identifies 'MS' as error-prone (can mean morphine sulfate or magnesium sulfate), but in standard pain
management context, it typically denotes morphine sulfate. 'IV' is intravenous, 'PRN' is as needed, and 'q4h'
is every 4 hours. The other options misinterpret the abbreviation or route.
2. Which abbreviation on the Joint Commission 'Do Not Use' list is correctly paired with its
safe alternative?
[ ] A. U (unit) -> write 'unit'
[ ] B. QD (every day) -> write 'daily'
[ ] C. QOD (every other day) -> write 'every other day'
[ ] D. All of the above
CORRECT: D. All of the above
The Joint Commission prohibits U, QD, QOD, and others due to misinterpretation risk. Safe alternatives are
to write out 'unit,' 'daily,' and 'every other day.' All listed pairs are correct.
3. In a progress note, the abbreviation 'BS' is used. Which context most reliably indicates
'blood sugar' rather than 'bowel sounds'?
[ ] A. Notation in a diabetic patient's glucose log
[ ] B. Auscultation findings in the abdomen
[ ] C. Postoperative ileus assessment
[ ] D. Emergency department triage note
CORRECT: A. Notation in a diabetic patient's glucose log
'BS' is ambiguous and error-prone; it can mean blood sugar or bowel sounds. In a diabetic patient's glucose
log, context clearly points to blood sugar. The other contexts refer to abdominal assessment where 'BS'
would mean bowel sounds.
4. A prescription uses 'U' for units of insulin. According to ISMP, what is the primary risk
and recommended practice?
[ ] A. Risk of misreading as zero or four; write 'unit'
[ ] B. Risk of misreading as milliliter; write 'mL'
[ ] C. Risk of misreading as microgram; write 'mcg'
HIGHP - Page 2 of 30
, [ ] D. Risk of misreading as international unit; write 'IU'
CORRECT: A. Risk of misreading as zero or four; write 'unit'
ISMP lists 'U' as error-prone because it can be misread as the number 0 or 4, leading to tenfold overdoses.
The safe practice is to write 'unit' in full. The other options are incorrect alternatives.
5. Which abbreviation is correctly interpreted as 'nothing by mouth' and is acceptable in
current practice?
[ ] A. NPO
[ ] B. NP
[ ] C. NBM
[ ] D. NPO is error-prone and should be written out
CORRECT: A. NPO
NPO (nil per os) is widely accepted and not on the Joint Commission 'Do Not Use' list. NP typically means
nurse practitioner or nasopharyngeal; NBM is not standard. NPO remains standard for 'nothing by mouth.'
6. A patient's chart notes 'SOB on exertion.' Which alternative abbreviation could reduce
ambiguity according to safety standards?
[ ] A. Shortness of breath
[ ] B. Dyspnea
[ ] C. DOE (dyspnea on exertion)
[ ] D. All of the above
CORRECT: D. All of the above
'SOB' can be misread as 'shortness of breath' or 'side of body' but is also on some error-prone lists. Writing
'shortness of breath' or using 'dyspnea' or 'DOE' clarifies meaning. All options are acceptable alternatives.
7. Which abbreviation is correctly matched with its meaning in the context of vital signs?
[ ] A. BP = blood pressure
[ ] B. BP = body pulse
[ ] C. BP = breathing pattern
[ ] D. BP = blood perfusion
CORRECT: A. BP = blood pressure
BP universally stands for blood pressure in vital signs documentation. The other expansions are not standard
and would be considered incorrect in clinical practice.
