Medical Terminology, Anatomy, and Pathophysiology
Q1: The medical root word "hepat/o" refers to which specific organ?
A. Heart
B. Kidney
C. Liver [CORRECT]
D. Pancreas
Correct Answer: C
Rationale: The best answer is C because "hepat/o" is the standard medical combining form
for the liver, which is foundational knowledge for accurately coding hepatic conditions.
Q2: Which anatomical plane divides the human body into anterior (front) and posterior
(back) portions?
A. Sagittal plane
B. Transverse plane
C. Frontal (coronal) plane [CORRECT]
D. Midsagittal plane
Correct Answer: C
Rationale: This choice is correct because the frontal, or coronal, plane is the anatomical
reference that vertically separates the body into front and back sections.
Q3: A patient is diagnosed with Type 1 Diabetes Mellitus. What is the underlying
pathophysiology of this condition?
A. Cellular resistance to insulin production
B. Autoimmune destruction of pancreatic beta cells [CORRECT]
C. Excessive glucagon secretion from the alpha cells
D. Viral infection of the adrenal glands
Correct Answer: C
Rationale: This aligns with the disease process, as Type 1 Diabetes is characterized by the
immune system attacking insulin-producing beta cells in the pancreas.
Q4: What is the primary difference between a surgical "-ectomy" and an "-ostomy"?
A. An -ectomy removes an organ, while an -ostomy creates a new opening. [CORRECT]
B. An -ectomy repairs an organ, while an -ostomy removes it.
C. Both terms mean the same thing and are used interchangeably.
D. An -ectomy is a diagnostic procedure, while an -ostomy is therapeutic.
,Correct Answer: C
Rationale: The best answer is C because "-ectomy" denotes surgical excision or removal,
whereas "-ostomy" denotes the surgical creation of an artificial opening.
Q5: In ophthalmology, where is the macula located?
A. In the anterior chamber of the eye
B. In the center of the retina [CORRECT]
C. Within the vitreous humor
D. On the surface of the cornea
Correct Answer: C
Rationale: This choice is correct because the macula is the small, highly sensitive area in the
center of the retina responsible for sharp, central vision.
Q6: A clinical note states: "Pt presents with worsening dyspnea, orthopnea, and bilateral
pitting edema." Based on this snippet, which pathophysiological process is most likely
occurring?
A. Acute asthma exacerbation
B. Congestive heart failure [CORRECT]
C. Gastroesophageal reflux disease
D. Pneumothorax
Correct Answer: C
Rationale: This matches the principle that the combination of shortness of breath, difficulty
breathing when lying flat, and fluid retention are classic hallmarks of heart failure.
Q7: What is the primary function of the alveoli in the respiratory system?
A. To filter dust and debris from inhaled air
B. To facilitate gas exchange between the air and the blood [CORRECT]
C. To produce mucus for trapping pathogens
D. To warm and humidify incoming air
Correct Answer: C
Rationale: The best answer is C because alveoli are the tiny air sacs in the lungs where
oxygen and carbon dioxide are exchanged with the capillaries.
Q8: When reviewing a pathology report, how does a coder distinguish a benign neoplasm
from a malignant one?
A. Benign neoplasms are always coded as carcinomas.
B. Malignant neoplasms invade surrounding tissues and can metastasize. [CORRECT]
C. Benign neoplasms grow much faster than malignant ones.
D. Malignant neoplasms are encapsulated and do not spread.
Correct Answer: C
Rationale: This choice is correct because malignancy is defined by the uncontrolled growth,
local tissue invasion, and potential to spread (metastasize) to distant sites.
Q9: Which medical term describes the presence of blood in the urine?
A. Hematemesis
B. Hematuria [CORRECT]
C. Hematochezia
, D. Hemoptysis
Correct Answer: C
Rationale: This aligns with medical terminology, where "hemat-" means blood and "-uria"
refers to urine, indicating blood in the urinary tract.
Q10: A patient is diagnosed with GERD. What is the primary pathophysiological mechanism
of this disease?
A. Inadequate production of stomach acid
B. Incompetence of the lower esophageal sphincter [CORRECT]
C. Bacterial infection of the gastric mucosa
D. Obstruction of the pyloric valve
Correct Answer: C
Rationale: The best answer is C because Gastroesophageal Reflux Disease is primarily caused
by the weakening or relaxation of the lower esophageal sphincter, allowing stomach acid to
flow backward.
Q11: Which three small bones make up the ossicles in the middle ear?
A. Malleus, incus, and stapes [CORRECT]
B. Cochlea, vestibule, and semicircular canals
C. Tympanic membrane, eustachian tube, and mastoid
D. Frontal, parietal, and temporal
Correct Answer: C
Rationale: This choice is correct because the malleus (hammer), incus (anvil), and stapes
(stirrup) are the specific ossicles that transmit sound vibrations in the middle ear.
Q12: What does the term "idiopathic" mean in a diagnostic context?
A. Caused by a known genetic mutation
B. Arising spontaneously or from an obscure or unknown cause [CORRECT]
C. Resulting from a surgical complication
D. Inherited from a parent
Correct Answer: C
Rationale: This matches the principle that "idiopathic" is used when the underlying cause of
a disease or condition cannot be determined.
Q13: A 22-year-old male presents to the ED with severe right lower quadrant abdominal
pain, nausea, and rebound tenderness. What is the most likely diagnosis?
A. Cholecystitis
B. Acute appendicitis [CORRECT]
C. Diverticulitis
D. Peptic ulcer disease
Correct Answer: C
Rationale: The best answer is C because right lower quadrant pain with rebound tenderness
(McBurney's point) is the classic clinical presentation of acute appendicitis.
Q14: A patient undergoes a colostomy. What does this procedure entail?
A. Surgical removal of the entire colon
B. Surgical creation of an opening from the colon to the abdominal wall [CORRECT]
