Guide - Master Review Notes 2026
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 cirrhosis develops ascites. Which mechanism is primarily responsible?
A) Decreased hepatic lymph production
B) Portal hypertension and hypoalbuminemia
C) Increased renal excretion of sodium
D) Enhanced hepatic synthesis of albumin
*Correct Answer: B) Portal hypertension and hypoalbuminemia *
Rationale: Ascites in cirrhosis results from portal hypertension, which increases hydrostatic
pressure, and hypoalbuminemia, which decreases oncotic pressure. Splanchnic
vasodilation also activates RAAS, promoting sodium and water retention.
Question 2
A patient with cirrhosis has an elevated ammonia level and confusion. Which condition
is most likely?
A) Hepatic encephalopathy
B) Acute pancreatitis
C) Peptic ulcer disease
D) Cholecystitis
,*Correct Answer: A) Hepatic encephalopathy *
Rationale: Hepatic encephalopathy results from accumulation of ammonia and other
neurotoxins due to impaired hepatic detoxification and portosystemic shunting.
Question 3
A patient with acute pancreatitis has a serum calcium of 7.2 mg/dL. What is the
mechanism of hypocalcemia?
A) Fat saponification
B) Hyperparathyroidism
C) Vitamin D toxicity
D) Renal failure
*Correct Answer: A) Fat saponification *
Rationale: Pancreatic fat necrosis releases fatty acids that bind calcium (saponification),
causing hypocalcemia.
Question 4
Which finding is most characteristic of a peptic ulcer caused by H. pylori?
A) Diffuse superficial inflammation
B) A solitary ulcer in the duodenal bulb
C) Multiple ulcers throughout the colon
D) Esophageal varices
*Correct Answer: B) A solitary ulcer in the duodenal bulb *
Rationale: H. pylori–associated peptic ulcers commonly occur in the duodenal bulb or
gastric antrum.
,Question 5
A patient with ulcerative colitis has bloody diarrhea. Which layer of the bowel wall is
primarily inflamed?
A) Mucosa and submucosa
B) Muscularis propria
C) Serosa
D) Entire bowel wall (transmural)
*Correct Answer: A) Mucosa and submucosa *
Rationale: Ulcerative colitis is a mucosal and submucosal inflammatory disease, typically
starting in the rectum and extending proximally.
Question 6
A patient with Crohn disease has transmural inflammation. Which complication is most
likely?
A) Fistula formation
B) Toxic megacolon
C) Pseudopolyps
D) Superficial ulcers only
*Correct Answer: A) Fistula formation *
Rationale: Transmural inflammation in Crohn disease can penetrate the bowel wall,
causing fistulas, strictures, and abscesses.
Question 7
A patient with a small bowel obstruction has vomiting and abdominal distention. Which
electrolyte imbalance is most likely?
A) Hypokalemia and metabolic alkalosis
B) Hyperkalemia and metabolic acidosis
C) Hypernatremia and respiratory acidosis
D) Hypocalcemia and respiratory alkalosis
, *Correct Answer: A) Hypokalemia and metabolic alkalosis *
Rationale: Small bowel obstruction with vomiting causes loss of gastric acid and
potassium, leading to hypokalemia and metabolic alkalosis.
Question 8
A patient with diverticulitis has left lower quadrant pain. What is the underlying
pathophysiology?
A) Inflammation of a colonic diverticulum
B) Ischemia of the small bowel
C) Obstruction of the appendix
D) Inflammation of the gallbladder
*Correct Answer: A) Inflammation of a colonic diverticulum *
Rationale: Diverticulitis is inflammation/infection of a diverticulum, most commonly in the
sigmoid colon (left lower quadrant).
Question 9
A patient with hepatitis B has a positive HBsAg and IgM anti-HBc. What does this
indicate?
A) Acute hepatitis B infection
B) Chronic hepatitis B infection
C) Resolved hepatitis B infection
D) Vaccination against hepatitis B
*Correct Answer: A) Acute hepatitis B infection *
Rationale: HBsAg indicates active infection, and IgM anti-HBc indicates acute infection.
Chronic infection would have IgG anti-HBc and possibly HBeAg.
