HESI PT2 2026 INTENSIVE PREP EDITION: UPDATED PRACTICE QUESTIONS, EXPERT RATIONALES & PROVEN STRATEGIES TO HELP YOU PASS WITH CONFIDENCE ON YOUR FIRST ATTEMPT Question 1 Which set of clinical manifestations unequivocally indicates late-stage, critically elevated intracranial pressure, demanding immediate neurosurgical intervention due to impending uncal herniation? o Profound polyuria, constricted pupils responsive to light, and decorticate posturing o Projectile emesis, fixed and dilated ipsilateral pupil, decerebrate rigidity, and profound bradycardia o Persistent intense thirst, mydriatic pupils with hippus, and Cheyne-Stokes respirations o Altered mental status with hyperreflexia, transient visual obscurations, and tachycardia with hypertension Explanation >>>The combination of projectile vomiting, fixed and dilated ipsilateral pupil, decerebrate posturing, and profound bradycardia represents a critical constellation of signs indicative of severe, rapidly escalating ICP with imminent brainstem compression, particularly uncal herniation. The specific pupillary change signals oculomotor nerve compromise, while decerebrate rigidity indicates severe brainstem dysfunction. Bradycardia is a component of Cushing's triad, indicating severe cerebral ischemia and pressure on medullary centers. 2. Question 2Differentiate the pathophysiological bedrock of Amyotrophic Lateral Sclerosis (ALS) from other neurodegenerative or neuromuscular afflictions, specifically focusing on the primary cellular and molecular mechanisms. o The hallmark of ALS is the insidious, progressive demise of upper and
