HESI RN: Pathophysiology Comprehensive Exit Examination (2026
Blueprint) With Correct Answers
1. What specific compensatory mechanism does the body initiate during the early stages of
hypovolemic shock to maintain perfusion to vital organs?
Correct Answer: Peripheral vasoconstriction and tachycardia driven by catecholamine
release
2. Which structural change occurs in the heart muscle as a direct compensatory response to
chronic, untreated systemic hypertension?
Correct Answer: Left ventricular hypertrophy
3. What specific type of cell adaptation occurs in the lower esophagus of a patient with chronic
gastroesophageal reflux disease (GERD), commonly known as Barrett's esophagus?
Correct Answer: Metaplasia
4. Which arterial blood gas (ABG) result does the nurse expect to find in a patient who has been
experiencing severe, protracted vomiting for 48 hours?
Correct Answer: Metabolic alkalosis
5. What fluid and electrolyte shift occurs during the acute phase of a major burn injury due to
increased capillary permeability?
Correct Answer: Hyperkalemia and movement of fluid from intravascular to interstitial
spaces
6. Which intracellular electrolyte moves out of the cell and into the bloodstream during a
severe state of metabolic acidosis?
Correct Answer: Potassium
7. What type of hypersensitivity reaction is occurring when a patient develops sudden laryngeal
edema, bronchospasm, and severe hypotension minutes after receiving an intravenous
antibiotic?
Correct Answer: Type I IgE-mediated hypersensitivity reaction
8. What specific clinical manifestation indicates that a patient with advanced liver cirrhosis is
developing portal hypertension?
Correct Answer: Esophageal varices
9. Which specific serum laboratory value is the most sensitive and specific biomarker for
confirming myocardial tissue injury following an acute coronary event?
Correct Answer: Troponin I
10. What underlying pathophysiological process triggers the intense, crushing chest pain
associated with an acute myocardial infarction?
Correct Answer: Myocardial tissue ischemia due to a complete occlusion of a coronary artery
11. What dynamic mechanical failure is the primary cause of pulmonary edema in a patient
diagnosed with acute left-sided heart failure?
Correct Answer: Increased hydrostatic pressure in the pulmonary capillaries forcing fluid into
the alveoli
, 12. Which physical finding does the nurse expect to note when evaluating a patient presenting
with an acute exacerbation of right-sided heart failure?
Correct Answer: Jugular venous distension (JVD)

separates and internal visceral organs protrude through the wound bed?
Correct Answer: Evisceration
14. What objective score on the Glasgow Coma Scale (GCS) represents the threshold at which a
patient is considered in a deep comatose state, necessitating immediate airway protection?
Correct Answer: Eight or less
15. What specific vascular change is responsible for the development of orthostatic hypotension
when an immobile patient is assisted to stand up too quickly?
Correct Answer: Peripheral vasodilation causing a rapid drop in venous return to the heart
16. What respiratory abnormality is pathologically characterized by the chronic, irreversible
destruction of alveolar walls and subsequent air trapping?
Correct Answer: Emphysema
17. What life-threatening chest wall condition is characterized by a one-way valve mechanism
that shifts the mediastinum and compresses the vena cava?
Correct Answer: Tension pneumothorax
18. What specific clinical triad outlines the primary predisposing vectors for deep vein
thrombosis: venous stasis, endothelial damage, and blood hypercoagulability?
Correct Answer: Virchow's triad
19. Which diagnostic laboratory value is the primary marker used to confirm an active, acute
systemic bacterial infection?
Correct Answer: Elevated white blood cell (WBC) count with a left shift
20. What specific neuromuscular disorder is caused by an autoimmune destruction of
acetylcholine receptors at the neuromuscular junction?
Correct Answer: Myasthenia gravis
21. What chronic, progressive neurodegenerative disease is pathologically characterized by a
profound depletion of dopamine-producing neurons within the substantia nigra?
Correct Answer: Parkinson's disease
22. Which specific type of shock is driven by a complete loss of sympathetic vasomotor tone
following a high-level cervical spinal cord injury?
Correct Answer: Neurogenic shock
23. What specific type of generalized seizure is characterized by an abrupt, brief lapse of
consciousness without loss of postural tone, commonly seen in pediatric populations?
Correct Answer: Absence seizure
24. What acute condition involves a sudden, painful mechanical twisting or rotation of a loop of
bowel around its mesenteric attachment site, risking tissue infarction?
Correct Answer: Volvulus
