1 HESI PT1 2026 POWER REVIEW: REAL EXAM-STYLE QUESTIONS, SMART STRATEGIES & HIGH-YIELD ANSWERS TO HELP YOU CRUSH THE TEST ON YOUR FIRST TRY Question 1 In the pathological progression of acute cellular stress, phenomena such as hydropic swelling and macrovesicular steatosis occur most proximally to the point where membrane-bound organelle integrity is compromised, preceding irremediable cellular demise. Which of the following conditions most critically predisposes a cell to irreversible damage via ATP depletion and subsequent failure of the sodium-potassium pump, particularly within a milieu of unremitted anoxia? o Sustained disruption of oxidative phosphorylation pathway efficiency, rendering electron transport chain inoperative. o Paradoxical enhancement of adenosine triphosphate synthase activity leading to substrate exhaustion. o Loss of intracellular calcium homeostasis, leading to mitochondrial permeability transition pore opening. o Profound intracellular alkalosis stemming from carbonic anhydrase dysregulation. Explanation >>>>Cellular hypoxia fundamentally impairs ATP production through oxidative phosphorylation, leading to the failure of ATP-dependent pumps, such as the sodium-potassium pump, and subsequent cellular edema and derangement of ionic gradients. 2. Question 2 A 75-year-old patient who has undergone prolonged decumbency post-surgical intervention presents with insidious onset of symmetric, distal lower extremity weakness and demonstrable reduction in muscle bulk. This clinical presentation,2 in the
