,1. Multiple Choice: Which of the following is a primary
cause of increased intracranial pressure?
a) Brain tumors
b) Cerebral atrophy
c) Hydrocephalus
d) All of the above
Answer: d) All of the above
Rationale: Brain tumors, cerebral atrophy, and
hydrocephalus can all lead to increased intracranial
pressure, which is a critical condition that can affect brain
function.
2. Fill-in-the-Blank: The ________ is the region of the brain
responsible for regulating the autonomic nervous system.
Answer: Hypothalamus
Rationale: The hypothalamus is a crucial brain region that
controls the autonomic nervous system, influencing heart
rate, blood pressure, and digestion.
3. True/False: The pathophysiology of asthma involves the
irreversible enlargement of the airway's bronchioles.
Answer: False
Rationale: Asthma is characterized by reversible airway
obstruction due to inflammation and hyper-responsiveness,
not irreversible enlargement.
4. Multiple Response: Select all that apply. Which factors
contribute to the pathogenesis of atherosclerosis?
a) Endothelial injury
b) Oxidative stress
c) High-density lipoprotein (HDL) levels
©2024/2025
, d) Immune responses
Answer: a), b), d)
Rationale: Endothelial injury, oxidative stress, and
immune responses are all contributors to the development
of atherosclerosis. HDL is often considered protective
against the condition.
5. Multiple Choice: What is the hallmark sign of left-sided
heart failure?
a) Peripheral edema
b) Jugular vein distension
c) Pulmonary congestion
d) Hepatomegaly
Answer: c) Pulmonary congestion
Rationale: Pulmonary congestion is indicative of left-sided
heart failure as the left ventricle fails to pump blood
effectively, leading to fluid accumulation in the lungs.
6. Fill-in-the-Blank: In diabetes mellitus, the lack of insulin or
resistance to insulin leads to a state of ________.
Answer: Hyperglycemia
Rationale: Without sufficient insulin action, glucose cannot
enter cells and remains in the bloodstream, causing
hyperglycemia.
7. True/False: Chronic obstructive pulmonary disease
(COPD) is characterized by a decrease in total lung
capacity.
Answer: False
Rationale: COPD typically leads to an increase in total
lung capacity due to air trapping and lung hyperinflation, not
a decrease.
