EXAM OVERVIEW
Course: Pathophysiology Comprehensive Exam
Institution: Generic Healthcare Program
Exam Type: Comprehensive Exam
Question Count: 200 Questions
Format: Multiple Choice with Verified Answers and Complete Rationales
Focus Areas: Comprehensive pathophysiology including cellular injury, inflammation, immune disorders,
genetic disorders, fluid/electrolyte imbalances, and all body systems
QUESTION 1
A client presents with fatigue, pallor, and shortness of breath. Laboratory results: hemoglobin 8.5 g/dL, MCV
105 fL, vitamin B12 150 pg/mL (normal 200-900). The nurse practitioner suspects which type of anemia?
A) Iron deficiency anemia
B) Pernicious anemia
C) Aplastic anemia
D) Sickle cell anemia
Correct Answer: B
Rationale: Pernicious anemia is a macrocytic anemia (high MCV) caused by vitamin B12 deficiency. Iron
deficiency anemia (A) is microcytic (low MCV). Aplastic anemia (C) presents with pancytopenia. Sickle cell
anemia (D) presents with sickle-shaped cells and hemolytic crises.
QUESTION 2
A client with heart failure presents with dyspnea, orthopnea, and peripheral edema. The nurse practitioner
understands that the primary pathophysiological mechanism of heart failure is:
A) Decreased cardiac output
B) Increased cardiac output
,2
C) Decreased systemic vascular resistance
D) Increased systemic vascular resistance
Correct Answer: A
Rationale: Heart failure is characterized by decreased cardiac output, leading to fluid retention and
congestion. Increased cardiac output (B) is not the mechanism. Decreased SVR (C) and increased SVR (D) are
not the primary mechanism.
QUESTION 3
A client with COPD presents with worsening dyspnea. Arterial blood gas: pH 7.28, PaCO2 65 mmHg, PaO2
50 mmHg, HCO3 28 mEq/L. The nurse practitioner interprets these results as:
A) Respiratory alkalosis
B) Respiratory acidosis
C) Metabolic acidosis
D) Metabolic alkalosis
Correct Answer: B
Rationale: The pH is low (7.28) indicating acidosis. PaCO2 is elevated (65 mmHg) indicating respiratory
acidosis. HCO3 is elevated (28 mEq/L) indicating metabolic compensation. This is respiratory acidosis with
metabolic compensation.
QUESTION 4
A client with diabetes presents with a foot ulcer. The nurse practitioner understands that the most common
cause of diabetic foot ulcers is:
A) Peripheral neuropathy
B) Peripheral artery disease
C) Venous insufficiency
D) Infection
Correct Answer: A
Rationale: Peripheral neuropathy is the most common cause of diabetic foot ulcers, leading to decreased
sensation and unrecognized trauma. Peripheral artery disease (B) contributes but is not the most common.
Venous insufficiency (C) is more common in venous stasis ulcers. Infection (D) is a complication, not a cause.

QUESTION 5
A client with hypertension is prescribed lisinopril. The nurse practitioner understands that lisinopril works
by:
A) Blocking angiotensin II receptors
B) Blocking the conversion of angiotensin I to angiotensin II
C) Blocking beta-1 receptors
D) Blocking calcium channels
Correct Answer: B
Rationale: Lisinopril is an ACE inhibitor that works by blocking the conversion of angiotensin I to
angiotensin II. ARBs (A) block angiotensin II receptors. Beta-blockers (C) block beta-1 receptors. Calcium
channel blockers (D) block calcium channels.
QUESTION 6
A client with osteoporosis is prescribed alendronate. The nurse practitioner should instruct the client to:
A) Take with food
B) Take on an empty stomach with a full glass of water and remain upright for 30 minutes
C) Take with milk
D) Take at bedtime
Correct Answer: B
Rationale: Alendronate should be taken on an empty stomach with a full glass of water, and the client should
remain upright for 30 minutes to prevent esophagitis. Taking with food (A) or milk (C) reduces absorption.
Bedtime (D) increases the risk of esophagitis.
QUESTION 7
A client with atrial fibrillation presents with palpitations. The nurse practitioner prescribes metoprolol. The
nurse practitioner understands that metoprolol works by:
A) Blocking beta-1 receptors
B) Blocking beta-2 receptors
C) Blocking both beta-1 and beta-2 receptors
D) Blocking alpha receptors
, 4
Correct Answer: A
Rationale: Metoprolol is a cardioselective beta-1 blocker that works by blocking beta-1 receptors in the heart.
Non-selective beta-blockers (C) block both beta-1 and beta-2 receptors. Alpha-blockers (D) block alpha
receptors.
QUESTION 8
A client with HIV presents with a CD4 count of 80 cells/mm³. The nurse practitioner should start prophylaxis
for:
A) PCP only
B) MAC only
C) Both PCP and MAC
D) Neither
Correct Answer: A
Rationale: PCP prophylaxis is recommended when CD4 < 200 cells/mm³. MAC prophylaxis is recommended
when CD4 < 50 cells/mm³. At CD4 80, only PCP prophylaxis is indicated.
QUESTION 9
A client with Parkinson's disease is prescribed carbidopa-levodopa. The nurse practitioner understands that
carbidopa:
A) Enhances the effects of levodopa in the brain
B) Prevents peripheral breakdown of levodopa
C) Increases absorption of levodopa
D) Reduces side effects of levodopa
Correct Answer: B
Rationale: Carbidopa prevents peripheral breakdown of levodopa by inhibiting dopa decarboxylase, allowing
more levodopa to reach the brain. It does not enhance effects (A), increase absorption (C), or reduce side
effects (D).
