NUR 504 3P APEA Exam - Advanced Pathophysiology /
Advanced Pharmacology / Advanced Physical Assessment
Practice Questions with Verified Correct Answers & Detailed
Explanations – Latest Update 2026/2027.
Question 1
A patient presents with inflammation caused by tissue injury. Which
physiological process occurs during the inflammatory response?
A. Decreased blood flow to affected tissues
B. Release of inflammatory mediators causing vasodilation
C. Suppression of immune cell activity
D. Complete inhibition of cytokine production
Correct Answer: B. Release of inflammatory mediators causing
vasodilation
Explanation:
Inflammation is a protective response involving immune cells, blood vessels,
and molecular mediators. Injury triggers release of histamine, prostaglandins,
cytokines, and other mediators that cause vasodilation, increased vascular
permeability, redness, swelling, heat, and pain.
Question 2
A nurse practitioner is reviewing a patient’s laboratory results. Which finding
is most consistent with an acute bacterial infection?
A. Increased neutrophil count
B. Increased eosinophils
C. Decreased inflammatory markers
D. Reduced white blood cell production
Correct Answer: A. Increased neutrophil count

,Explanation:
Neutrophils are the primary white blood cells involved in acute bacterial
infections. Neutrophilia commonly occurs as the immune system responds to
bacterial pathogens.
Question 3
The primary purpose of apoptosis is:
A. Uncontrolled cell growth
B. Programmed cell death to maintain tissue balance
C. Formation of bacterial colonies
D. Increased inflammation
Correct Answer: B. Programmed cell death to maintain tissue balance
Explanation:
Apoptosis is a controlled process of cellular self-destruction. It removes
damaged, infected, or unnecessary cells while preventing excessive
inflammation.
Question 4
A patient with chronic inflammation is at increased risk for:
A. Tissue damage and fibrosis
B. Immediate healing only
C. Reduced immune activity
D. Elimination of all disease processes
Correct Answer: A. Tissue damage and fibrosis
Explanation:
Chronic inflammation results in prolonged immune activation, which may
lead to continued tissue injury, abnormal repair, scarring, and fibrosis.

,Question 5
Which immune cell is primarily responsible for producing antibodies?
A. T lymphocyte
B. B lymphocyte
C. Neutrophil
D. Macrophage
Correct Answer: B. B lymphocyte
Explanation:
B lymphocytes differentiate into plasma cells that produce antibodies.
Antibodies provide humoral immunity by targeting specific antigens.
Question 6
A patient with an autoimmune disorder experiences symptoms because:
A. The immune system attacks the body’s own tissues
B. The immune system is completely absent
C. Bacteria permanently replace immune cells
D. The patient cannot produce antibodies
Correct Answer: A. The immune system attacks the body’s own tissues
Explanation:
Autoimmune diseases occur when immune tolerance fails and immune cells
mistakenly identify normal body tissues as foreign.
Question 7
A mutation affecting proto-oncogenes may result in:
A. Increased regulation of cell growth
B. Uncontrolled cellular proliferation
3|Page
, C. Complete prevention of cancer
D. Reduced DNA activity only
Correct Answer: B. Uncontrolled cellular proliferation
Explanation:
Proto-oncogenes normally regulate cell growth. Mutations can convert them
into oncogenes, promoting abnormal cell division.
Question 8
The nurse practitioner understands that genetic mutations may contribute to
cancer by causing:
A. Loss of normal cell cycle regulation
B. Improved DNA repair
C. Increased apoptosis
D. Elimination of abnormal cells
Correct Answer: A. Loss of normal cell cycle regulation
Explanation:
Cancer develops when mutations disrupt mechanisms controlling cell
division, DNA repair, and programmed cell death.
Question 9
Which hormone is primarily responsible for increasing blood glucose levels
during stress?
A. Insulin
B. Cortisol
C. Melatonin
D. Oxytocin
Correct Answer: B. Cortisol
