Question 1: What is the meaning of the medical root "cardi/o"?
A. Lung
B. Liver
C. Heart
D. Kidney
CORRECT ANSWER: C. Heart
RATIONALE:The root "cardi/o" is derived from the Greek word "kardia" meaning heart.
This root appears in terms such as cardiology (study of the heart), cardiac (pertaining to
the heart), and cardiomegaly (enlargement of the heart). Understanding this
foundational root is essential for interpreting cardiovascular terminology.
Question 2: Which prefix indicates "before" or "in front of"?
A. post-
B. pre-
C. sub-
D. hyper-
CORRECT ANSWER: B. pre-
RATIONALE:The prefix "pre-" means before or in front of in time, place, or order.
Examples include preoperative (before surgery), prenatal (before birth), and preaxial (in
front of the axis). "Post-" means after, "sub-" means under, and "hyper-" means above or
excessive.
Question 3: The suffix "-itis" indicates which of the following?
A. Surgical removal
B. Study of
C. Inflammation
D. Pain
CORRECT ANSWER: C. Inflammation
RATIONALE:The suffix "-itis" denotes inflammation of a specified body part. Common
examples include arthritis (inflammation of joints), bronchitis (inflammation of the
,bronchi), and dermatitis (inflammation of the skin). Recognizing this suffix helps
clinicians quickly identify inflammatory conditions.
Question 4: Which directional term refers to a structure located closer to the point
of attachment or origin?
A. Distal
B. Proximal
C. Lateral
D. Medial
CORRECT ANSWER: B. Proximal
RATIONALE:Proximal describes a position nearer to the point of attachment or the
trunk of the body. For example, the elbow is proximal to the wrist. Distal indicates
farther from the point of attachment, while medial and lateral refer to positions relative
to the midline.
Question 5: Which anatomical plane divides the body into superior and inferior
portions?
A. Sagittal plane
B. Frontal plane
C. Transverse plane
D. Coronal plane
CORRECT ANSWER: C. Transverse plane
RATIONALE:The transverse (or horizontal) plane divides the body into superior (upper)
and inferior (lower) sections. The sagittal plane divides the body into left and right
portions, while the frontal (coronal) plane separates anterior and posterior sections.
Question 6: What does the term "dermatology" refer to?
A. Study of bones
B. Study of the skin
C. Study of muscles
D. Study of nerves
CORRECT ANSWER: B. Study of the skin
RATIONALE:Dermatology combines the root "dermat/o" (skin) with the suffix "-logy"
(study of), meaning the branch of medicine focused on the skin, hair, nails, and related
conditions. Dermatologists diagnose and treat disorders such as eczema, psoriasis,
and skin cancers.
Question 7: The term "osteoporosis" literally translates to:
A. Bone infection
B. Bone fracture
, C. Porous bone
D. Bone tumor
CORRECT ANSWER: C. Porous bone
RATIONALE:Osteoporosis derives from "oste/o" (bone), "por/o" (pore or passage), and
the suffix "-osis" (abnormal condition), collectively meaning a condition of porous or
weakened bone structure. This metabolic bone disease increases fracture risk due to
decreased bone density.
Question 8: What does "bradycardia" indicate?
A. Rapid heart rate
B. Irregular heart rhythm
C. Slow heart rate
D. Heart enlargement
CORRECT ANSWER: C. Slow heart rate
RATIONALE:Bradycardia combines "brady-" (slow) with "cardia" (heart condition),
indicating a heart rate below 60 beats per minute in adults. This contrasts with
tachycardia (fast heart rate) and is clinically significant when causing symptoms like
dizziness or syncope.
Question 9: The medical term "dyspnea" refers to:
A. Cessation of breathing
B. Difficulty breathing
C. Rapid breathing
D. Noisy breathing
CORRECT ANSWER: B. Difficulty breathing
RATIONALE:Dyspnea stems from "dys-" (difficult, painful) and "-pnea" (breathing),
describing subjective shortness of breath or labored respiration. It is a common
symptom in conditions such as asthma, COPD, heart failure, and anxiety disorders.
Question 10: What is the meaning of the suffix "-ectomy"?
A. Incision into
B. Surgical removal
C. Examination of
D. Repair of
CORRECT ANSWER: B. Surgical removal
RATIONALE:The suffix "-ectomy" denotes surgical excision or removal of a body part.
Examples include appendectomy (removal of the appendix), mastectomy (removal of
breast tissue), and hysterectomy (removal of the uterus). It is distinct from "-otomy"
(incision) and "-plasty" (repair).
