A patient received Humulin NPH insulin at 7 am. He was nauseated and vomiting at lunchtime and cannot tolerate PO. If this patient develops manifestations of hypoglycemia, treatment would include: A. 25 ml of 50% dextrose in water (D50W). B. glucagon subcutaneously. C. 4 oz of apple juice. D. 100 ml of 5% dextrose in water (D5W). - A. 25 ml of 50% dextrose in water (D50W). A volume of 25 ml of D50W would provide 12.5 g of carbohydrate and 50 calories. A patient had a craniotomy 2 days...

A-a gradient formula and normal range Correct Answer-PAO2- PaO2 PAO2 = FiO2 x (Patm- Ph20) - (PCo2/RQ) PAO2 = 150 - (PCO2/0.8) Normal is 10-250 Increased A-a gradient Correct Answer-- VQ mismatch (ex. COPD, PE, PNA) - responds to 100% O2 - Right to left shunt (ex. ARDs - Decreased diffusion (ex. ILD) Normal A-a gradient Correct Answer-- Low mixed venous O2 (ex. high altitude) - Hypoventilation (ex. drug OD) Acute vs chronic pH changes (hypercapnia/respiratory acidosis) Correct Ans...
