QUESTION 1
A patient presents with cellular adaptation where one cell type is replaced by
another cell type that is better able to withstand an adverse environment. This
process is known as:
A) Dysplasia
B) Hyperplasia
C) Metaplasia
D) Neoplasia
Explanation: Metaplasia is a reversible change in which one adult cell type is
replaced by another adult cell type. It occurs in response to chronic
irritation or inflammation and represents an adaptive mechanism. If the
stimulus persists, metaplasia can progress to dysplasia.
QUESTION 2
Which of the following best describes dysplasia?
A) Increase in cell size
B) Increase in cell number
C) Disordered cellular growth with abnormal cell size, shape, and
organization
D) Replacement of one cell type with another
Explanation: Dysplasia is characterized by abnormal changes in cell size,
shape, and organization. It is considered a preneoplastic condition and can
,be reversible if the stimulus is removed. Persistent dysplasia may progress
to carcinoma in situ and eventually invasive cancer.
QUESTION 3
Barrett esophagus is an example of:
A) Dysplasia
B) Metaplasia
C) Hyperplasia
D) Neoplasia
Explanation: Barrett esophagus involves the replacement of normal
stratified squamous epithelium of the lower esophagus with simple
columnar epithelium. This occurs in response to chronic gastroesophageal
reflux disease (GERD). It is a classic example of metaplasia, not dysplasia.
QUESTION 4
Cervical intraepithelial neoplasia (CIN) is classified as:
A) Dysplasia
B) Metaplasia
C) Hyperplasia
D) Hypertrophy
Explanation: CIN represents abnormal growth of cervical epithelial cells and
is graded based on the degree of abnormality. It is a form of dysplasia that
can progress to cervical cancer if not treated. CIN is detected through Pap
smears and is often caused by human papillomavirus (HPV) infection.
, QUESTION 5
Endometrial hyperplasia is:
A) A normal physiologic occurrence
B) An abnormal proliferation of endometrial cells
C) A type of metaplasia
D) A normal response to ovulation
Explanation: Endometrial hyperplasia is an abnormal proliferation of
endometrial glands and stroma. It is NOT a normal physiologic occurrence.
It typically results from unopposed estrogen stimulation and can progress
to endometrial cancer. Risk factors include obesity, polycystic ovary
syndrome, and estrogen therapy without progesterone.
QUESTION 6
Which term describes the proportion of people with a disease who test positive
for that disease?
A) Specificity
B) Sensitivity
C) Reliability
D) Validity
Explanation: Sensitivity measures the proportion of people with a disease
who correctly test positive. High sensitivity means few false negatives. This
is important for screening tests where missing a diagnosis could have
