1. The study of disease processes aids in the understanding of
normal functions.
• A) True
• B) False
Answer: A
Rationale: Pathophysiology examines how normal
physiological processes are altered by disease.
Understanding these disruptions provides critical insight into
how the systems are supposed to function under normal
conditions .
2. Phase IV clinical drug trials involve testing a drug only on
the specific human population who have the condition that the
drug is intended to treat.
,Page 2 of 88
• A) True
• B) False
Answer: B
Rationale: Phase IV trials occur after FDA approval. They
monitor long-term safety and effectiveness across a diverse,
general population, not just the specific target condition
group .
3. Negative feedback results in a response that opposes the
original deviation from normal.
• A) True
• B) False
Answer: A
Rationale: This is the definition of negative feedback. It is a
self-regulating mechanism where the output of a system
shuts off or reduces the intensity of the initial stimulus (e.g.,
thermostat regulation) .

4. Blood clotting is an example of positive feedback since the
action of the effector opposes that of the stimulus.
• A) True
• B) False
Answer: B
Rationale: Blood clotting is positive feedback, but the
rationale is incorrect. Positive feedback amplifies the initial
stimulus (effector enhances the stimulus), rather than
opposing it .
5. A patient takes a daily thyroid hormone replacement
medication to maintain normal thyroid hormone levels. This is
an example of a negative feedback mechanism.
• A) True
• B) False
Answer: B
Rationale: This is a homeostatic replacement mechanism.
However, it is an open-loop control system (or "replacement
, Page 4 of 88
therapy"), not a negative feedback loop, because the
medication does not turn itself off in response to rising
hormone levels .
6. Stratified epithelial tissue provides little protection but
transports substances between the internal and external
environments.
• A) True
• B) False
Answer: B
Rationale: Stratified epithelium is designed for protection
(e.g., skin) against abrasion. Simple epithelium is
specialized for transport and exchange .
7. Sebaceous glands are responsible for the lubrication of the
skin.
• A) True
• B) False
Answer: A
