Cardiovascular System Terminology (10 Questions)
Medical Record Scenario 1
Physician Notes: "Patient presents with chest pain. Cardiac catheterization reveals 90%
stenosis of the left anterior descending artery. EKG shows ST-elevation in inferior leads
consistent with acute inferior wall MI. Treatment plan: CABG scheduled."
Q1: The physician notes indicate "90% stenosis of the left anterior descending artery."
The term "stenosis" means:
A. Dilation of the vessel opening
B. Hardening of the artery wall
C. Narrowing of a passage or opening [CORRECT]
D. Complete blockage of blood flow
Correct Answer: C
Rationale: Correct because stenosis means narrowing or constriction of a passage or
opening; in this context, it refers to the narrowed coronary artery; dilation is widening;
hardening describes arteriosclerosis; complete blockage is occlusion.
Q2: The abbreviation "MI" in the phrase "acute inferior wall MI" stands for:
A. Mitral insufficiency
,B. Myocardial infarction [CORRECT]
C. Mechanical injury
D. Metabolic index
Correct Answer: B
Rationale: Correct because MI stands for myocardial infarction, which is death of heart
muscle due to interrupted blood supply; while mitral insufficiency may be abbreviated
MI in some contexts, in cardiology and acute care settings MI universally means heart
attack.
Q3: Based on the findings of severe coronary artery stenosis and acute MI, the
physician recommends CABG rather than angioplasty. Which statement best explains
this treatment choice?
A. Angioplasty is only used for peripheral vein repair
B. CABG creates a new route around blocked arteries using grafted vessels [CORRECT]
C. CABG removes the diseased section of heart muscle
D. Angioplasty requires open-heart surgery while CABG is minimally invasive
Correct Answer: B
Rationale: Correct because CABG (coronary artery bypass graft) uses vessels harvested
from elsewhere in the body to bypass blocked coronary arteries and restore myocardial
perfusion; angioplasty is less invasive but may be insufficient for severe multi-vessel
disease; CABG does not remove heart muscle, and it is the more invasive open-chest
procedure.
Q4: The combining form "cardi/o" refers to:
, A. Blood vessel
B. Heart [CORRECT]
C. Chest
D. Lung
Correct Answer: B
Rationale: Correct because cardi/o is the combining form meaning heart; vascul/o and
angi/o refer to vessels; thorac/o means chest; pneum/o means lung.
Q5: A patient with "pericarditis" has inflammation of which structure?
A. The heart muscle
B. The inner lining of the heart
C. The outer sac surrounding the heart [CORRECT]
D. The valve between the atria and ventricles
Correct Answer: C
Rationale: Correct because pericarditis is inflammation of the pericardium, the fibrous
sac that encloses the heart; myocarditis affects heart muscle; endocarditis affects the
inner lining; the atrioventricular valve is not the pericardium.
Q6: The suffix "-megaly" means:
A. Tumor
B. Enlargement [CORRECT]
C. Inflammation
