HESI RN ADVANCED PATHOPHYSIOLOGY EXAM 2026/2027 | PRACTICE
QUESTIONS, VERIFIED ANSWERS & DETAILED RATIONALES
DOCUMENT OVERVIEW:
• This comprehensive practice exam contains evidence-based multiple-choice
questions designed to prepare you for the HESI RN Advanced Pathophysiology
examination, featuring verified answers with detailed clinical rationales that explain
the "why" behind each correct response.
• Study this material by working through questions systematically, reviewing
rationales for both correct and incorrect answers to reinforce pathophysiologic
concepts, and using marked questions to identify weak areas requiring additional
review of foundational nursing physiology and disease processes.
SECTION 1: CELLULAR PHYSIOLOGY & ADAPTATION
**1. A 45-year-old patient with chronic hypertension develops left ventricular
hypertrophy. This represents which type of cellular adaptation?
A) Atrophy
B) Metaplasia
C) Hyperplasia
D) Hypertrophy
E) Dysplasia
D) Hypertrophy
Rationale: Hypertrophy is an increase in cell size in response to increased
workload or demand. The left ventricle increases in size due to sustained pressure
overload from chronic hypertension. This is a reversible adaptive response if the
causative stimulus is removed. Atrophy involves decrease in cell size, metaplasia is
,conversion of one cell type to another, hyperplasia is increase in cell number, and
dysplasia is abnormal cell development.
**2. During tissue injury, which of the following best describes the process of
necrosis?
A) Programmed cell death with cellular fragmentation into membrane-bound
apoptotic bodies
B) Uncontrolled cell death with loss of membrane integrity and release of cellular
contents
C) Reversible cell injury with restoration of normal cellular function
D) Selective destruction of specific organelles while maintaining cell membrane
integrity
E) Gradual thinning of the cell membrane without affecting cytoplasmic contents
B) Uncontrolled cell death with loss of membrane integrity and release of
cellular contents
Rationale: Necrosis is uncontrolled, pathologic cell death resulting from severe
injury. It involves loss of membrane integrity, release of intracellular contents into
surrounding tissue causing inflammation, and inability to be reversed. This differs
from apoptosis (option A) which is programmed, orderly cell death. Options C
describes reversible injury, D is selective autophagy, and E is not a recognized cell
death mechanism.
**3. A patient develops hypertrophy of the right ventricle secondary to
chronic pulmonary disease. What is the primary stimulus for this cellular
adaptation?
A) Increased oxygen tension in pulmonary vessels
B) Increased workload and oxygen demand
C) Decreased growth hormone levels
,D) Increased parasympathetic stimulation
E) Decreased metabolic rate
B) Increased workload and oxygen demand
Rationale: Cellular hypertrophy occurs in response to increased functional
demands. Chronic pulmonary disease causes increased pulmonary vascular
resistance, forcing the right ventricle to work harder to pump blood through
resistant vessels. This sustained increased workload stimulates protein synthesis
and increased cell size. The other options do not represent the primary stimulus for
compensatory hypertrophy in cardiac tissue.
**4. Which of the following best explains why cells undergo hyperplasia in
response to tissue loss?
A) To decrease the overall metabolic demand of the tissue
B) To increase the total number of cells and restore tissue mass and function
C) To replace damaged cells with scar tissue
D) To reduce the workload on remaining functional cells
E) To activate the lymphatic drainage system
B) To increase the total number of cells and restore tissue mass and
function
Rationale: Hyperplasia is an increase in the number of cells, occurring as a
compensatory mechanism to restore tissue mass and functional capacity after loss.
This is particularly important in highly proliferative tissues like the liver, which can
regenerate after partial hepatectomy. Hyperplasia differs from hypertrophy
(increase in size) and works alongside it in many compensatory responses. The
other options do not accurately describe the physiologic purpose of hyperplasia.
, **5. A 60-year-old patient with Barrett's esophagus is found to have
metaplasia of the normal stratified squamous epithelium. What stimulus
typically causes this adaptation?
A) Chronic irritation from acid reflux and inflammation
B) Decreased blood supply to the esophageal mucosa
C) Increased parasympathetic nerve stimulation
D) Bacterial colonization of the esophageal lining
E) Excessive mechanical trauma from swallowing
A) Chronic irritation from acid reflux and inflammation
Rationale: Metaplasia is the conversion of one differentiated cell type to another.
In Barrett's esophagus, chronic exposure to gastric acid causes replacement of
normal stratified squamous epithelium with columnar epithelium adapted to
survive in an acidic environment. This is a reversible adaptation if the acid reflux is
controlled but represents a significant risk factor for adenocarcinoma. The chronic
irritation provides the stimulus for this protective metaplasia.
SECTION 2: INFLAMMATION & IMMUNE RESPONSE
**6. During acute inflammation, neutrophils migrate to the site of injury
through which process?
A) Passive diffusion across capillary membranes
B) Chemotaxis in response to inflammatory mediators and active diapedesis
C) Lymphatic vessel transport
D) Increased blood viscosity forcing cells through tissues
E) Osmotic gradient movement
B) Chemotaxis in response to inflammatory mediators and active
diapedesis
