Mr. Daniels, a 73-year-old male with a history of hypertension and mild chronic kidney disease, arrives in the Emergency Department after a 3-day episode of vomiting and diarrhea from presumed gastroenteritis. In the last 24 hours, he has barely eaten or drunk anything and feels extremely weak and dizzy when standing. Initial Assessment: Vital signs: T 36.2°C, HR 114, BP 86/54 (lying), 68/48 (sitting), RR 24, SpO₂ 97% (RA) Physical exam: Poor skin turgor, dry oral mucosa, cool extremities, decreased capillary refill Neuro: Alert but fatigued, periodic confusion Urine Output: 150 mL over the last 12 hours Labs: Na+ = 150 mmol/L (135-145) K+ = 3.0 mmol/L (3.5-5.0) Cl- = 112 mmol/L (98-106) HCO₃⁻ = 17 mmol/L (22-28) BUN = 42 mg/dL (7-20) Creatinine = 2.0 mg/dL (baseline 1.3 two months ago) Glucose = 98 mg/dL ABG: pH 7.30, PaCO₂ 32 mmHg, HCO₃⁻ 17 mmol/L, PaO₂ 96 mmHg Current Orders: Two large-bore IV lines placed Isotonic saline at 150 mL/hr Continuous cardiac monitoring Strict intake and output STAT repeat labs and telemetry updates ordered Based on labs and ABG, which metabolic acid-base disorder does Mr. Daniels have?

Mr. Thomas, a 69-year-old man, is admitted with complaints of generalized weakness, muscle cramps, and confusion. He has a history of heart failure and has been taking furosemide (“water pill”) for several weeks. On exam, blood pressure is 96/50 mmHg, heart rate is 112 bpm, and mucous membranes are dry. Lab results show: Na⁺: 128 mmol/L K⁺: 2.8 mmol/L Cl⁻: 94 mmol/L HCO₃⁻: 32 mmol/L BUN: 38 mg/dL Creatinine: 1.5 mg/dL Which lab value most directly reflects Mr. Thomas’s risk for cardiac arrhythmias?
