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 Mr. Daniels’ ABG reveals pH 7.30 and HCO₃⁻ 17 mmol/L. Which system is providing fast-acting compensation for his acid-base disturbance?

Hоlly puts а bоx intо the trunk of her cаr. Lаter, she drives around an unbanked curve that has a radius of 48 m. The speed of the car on the curve is 16 m/s, but the box remains stationary relative to the floor of the trunk. Determine the minimum coefficient of static friction for the box on the floor of the trunk.
