Introduction:
This practice exam contains 50 of the most-tested questions in advanced pathophysiology for
HESI RN candidates. Designed for nursing students, it covers cardiovascular, respiratory,
endocrine, renal, hematologic, and neurologic disorders, emphasizing critical concepts,
clinical reasoning, and high-yield exam content. Each question includes the correct
SELECTED CORRECT 100% answer and a clear rationale to support learning and exam
preparation.
1. A patient presents with severe hyperglycemia and fruity-
smelling breath. Which condition is most likely?
A. Hypoglycemia
B. Hyperosmolar hyperglycemic state
C. Diabetic ketoacidosis (DKA)
D. Insulinoma
SELECTED CORRECT 100% answer: C
Rationale: DKA is characterized by hyperglycemia, ketosis,
metabolic acidosis, and fruity breath due to acetone. This is a
high-yield HESI scenario.
2. Which lab value is most indicative of acute renal failure?
A. Serum potassium 4.0 mEq/L
B. BUN 40 mg/dL
,2|Page
C. Creatinine 3.2 mg/dL
D. Serum sodium 140 mEq/L
SELECTED CORRECT 100% answer: C
Rationale: Elevated creatinine reflects impaired glomerular
filtration and is a key marker for acute renal failure.
3. A patient with chronic liver disease develops jaundice.
Which lab finding supports this condition?
A. Elevated hematocrit
B. Increased bilirubin
C. Decreased ammonia
D. Low AST
SELECTED CORRECT 100% answer: B
Rationale: Jaundice occurs due to bilirubin accumulation,
commonly seen in liver disease.
4. Which electrolyte imbalance is most commonly associated
with chronic kidney disease?
A. Hypokalemia
B. Hyperkalemia
C. Hypernatremia
D. Hypocalcemia
SELECTED CORRECT 100% answer: B
Rationale: CKD impairs potassium excretion, leading to
hyperkalemia, a critical and high-yield complication.

5. A patient with heart failure has pulmonary edema. Which
symptom is expected?
A. Dry cough
B. Dyspnea and orthopnea
C. Polyuria
D. Bradycardia
SELECTED CORRECT 100% answer: B
Rationale: Pulmonary edema causes fluid accumulation in lungs,
leading to shortness of breath, especially when lying flat.
6. Which type of hypersensitivity reaction is responsible for
anaphylaxis?
A. Type I
B. Type II
C. Type I (IgE-mediated)
D. Type IV
SELECTED CORRECT 100% answer: C
Rationale: Type I hypersensitivity reactions are IgE-mediated and
can cause rapid, life-threatening systemic reactions.
7. A patient presents with a low-grade fever, fatigue, and
generalized lymphadenopathy. Which white blood cell
abnormality might be present?
A. Neutropenia
B. Lymphocytosis
C. Eosinopenia
D. Basophilia
