HESI Advanced Pathophysiology Actual Exam Prep Study
Guide - Master Review Notes 2026-2027
Excel in your advanced clinical boards with this high-yield study
guide built for the HESI Advanced Pathophysiology actual exam.
This document delivers complete breakdowns of cellular
alterations, complex organ system failures, genetics, and
advanced disease etiologies. Packed with realistic practice
questions and explicit rationales, it is engineered to ensure you hit
your program benchmark on the very first try.
Question 1
A patient with chronic kidney disease has a hemoglobin of 8.5 g/dL and a low
reticulocyte count. Which type of anemia is most likely?
A) Iron deficiency anemia
B) Anemia of chronic kidney disease
C) Hemolytic anemia
D) Megaloblastic anemia
*Correct Answer: B) Anemia of chronic kidney disease *
Rationale: CKD causes decreased erythropoietin production, leading to normocytic
normochromic anemia with a low reticulocyte count.
Question 2
A patient with end-stage renal disease receives epoetin alfa. Which adverse effect
requires monitoring?
A) Hypertension and thrombosis
B) Hypoglycemia
,C) Bradycardia
D) Hyperkalemia
*Correct Answer: A) Hypertension and thrombosis *
Rationale: Erythropoiesis-stimulating agents can cause hypertension and increase
thrombotic risk by raising hematocrit.
Question 3
A patient with acute kidney injury develops confusion, hypertension, and seizures. Which
complication is most likely?
A) Uremic encephalopathy
B) Hypoglycemia
C) Hypercalcemia
D) Hyponatremia
*Correct Answer: A) Uremic encephalopathy *
Rationale: Accumulation of urea and other toxins in AKI can cause uremic encephalopathy
with confusion, asterixis, seizures, and coma.
Question 4
A patient on hemodialysis develops headache, nausea, and confusion during treatment.
What is the most likely cause?
A) Dialysis disequilibrium syndrome
B) Hypotension
C) Hyperkalemia
D) Air embolism
*Correct Answer: A) Dialysis disequilibrium syndrome *
Rationale: Rapid osmotic shifts during dialysis cause cerebral edema, leading to headache,
nausea, confusion, and seizures.
,Question 5
A patient on peritoneal dialysis develops cloudy effluent and abdominal pain. What is
the most likely complication?
A) Peritonitis
B) Hernia
C) Hyperglycemia
D) Bleeding
*Correct Answer: A) Peritonitis *
Rationale: Cloudy peritoneal effluent with abdominal pain and fever indicates peritonitis,
the most common complication of peritoneal dialysis.
Question 6
A patient with hyperglycemic hyperosmolar state (HHS) has a blood glucose of 1,200
mg/dL and serum osmolality of 350 mOsm/kg. Which finding is most characteristic?
A) Minimal ketosis and severe dehydration
B) Profound ketosis
C) Metabolic acidosis
D) Rapid onset over hours
*Correct Answer: A) Minimal ketosis and severe dehydration *
Rationale: HHS typically occurs in type 2 diabetes with severe hyperglycemia,
hyperosmolality, and dehydration but minimal or absent ketosis.
Question 7
A patient with type 2 diabetes on a sulfonylurea develops sweating, tremors, and
confusion. What is the priority action?
A) Check blood glucose and administer 15 g of fast-acting carbohydrate
B) Administer another dose of sulfonylurea
, C) Encourage the patient to sleep
D) Call 911 immediately
*Correct Answer: A) Check blood glucose and administer 15 g of fast-acting
carbohydrate *
Rationale: Symptoms suggest hypoglycemia. The rule of 15 should be applied: check
glucose, give 15 g carbohydrate, recheck in 15 minutes.
Question 8
A patient with myxedema coma has hypothermia, bradycardia, and altered mental
status. Which medication is priority?
A) IV levothyroxine
B) Methimazole
C) Propranolol
D) Radioactive iodine
*Correct Answer: A) IV levothyroxine *
Rationale: Myxedema coma is a life-threatening complication of severe hypothyroidism
requiring immediate IV thyroid hormone replacement.
Question 9
A patient with a pheochromocytoma is being prepared for surgery. Which medication is
used preoperatively to control blood pressure?
A) Phenoxybenzamine
B) Propranolol
C) Metoprolol
D) Lisinopril
*Correct Answer: A) Phenoxybenzamine *
Rationale: Alpha-blockade with phenoxybenzamine is required before surgery to prevent
hypertensive crisis from catecholamine release.
