Clinical Pathophysiology Diagnosis & Treatment Handbook: Mechanism-Based Approaches to Cardiac, Pulmonary, Renal, Hepatic, Endocrine, and Hematologic Disease: 7

You are on rounds at 6:42 a.m., the patient's creatinine has tripled overnight, the anion gap is 28, the lactate is rising, and the resident is asking you whether to start bicarbonate, push insulin, intubate, or call nephrology — and the answer is in the integrated pathophysiology, not the order set. When clinical reasoning collapses into protocol-following, the patient with the unrecognized hepatorenal syndrome gets diuresed into dialysis, the patient with euglycemic DKA on the SGLT2 inhibitor goes home, and the chronic CO2 retainer gets ventilated to a pH of 7.6. This handbook installs the mechanism-based reasoning that contemporary internal medicine actually requires — so that every patient at every bedside gets the diagnosis their physiology is telling you. Inside this book: • Decode the ABG in sixty seconds — apply the six-step framework that catches mixed disorders even when the pH looks normal • Recognize decompensated cirrhosis at the bedside — diagnose hepatorenal syndrome with current criteria and start terlipressin before the kidney is lost • Navigate the four-pillar heart failure regimen — layer ARNI, beta-blocker, MRA, and SGLT2 inhibitor in HFrEF and HFpEF with confidence • Sequence modern CKD therapy — combine RAAS blockade, SGLT2 inhibitor, and finerenone with the trial evidence that supports each • Read the peripheral smear like a hematologist — identify schistocytes, sickle cells, and blasts that change management within the hour • Run acute stroke care to contemporary benchmarks — recognize the LVO, mobilize the team, and meet the door-to-needle and door-to-puncture targets that determine outcome • Apply the contemporary biologic and JAK inhibitor pharmacology — with the screening and surveillance that prevent the predictable complications For medical students transitioning to clinical training, residents, hospitalists, internists, nurses, nurse practitioners, and physician assistants who care for adults across the full inpatient and outpatient spectrum.
