Drug G comes from the pharmacy as 40mg/5cc. How many milliliters will you give to deliver 12 mg of drug? Dopamine comes prepared as 400mg in 250 ml D5W bags (1600 mcg/ml). You have been ordered to deliver 20 mcg/kg/min to a hypotensive ICU patient who weighs 76 kg (167.2 lbs). You use IV tubing with a drip factor of 60, meaning every 60 drops is equal to 1 milliliter (60 gtts/ml). How many drops per minute will you deliver...

Calculate the partial pressure of O2 (P02, mm Hg) in dry air in Arcata (sea level- assume atmospheric pressure of 760 mm Hg). Arcata air never gets fully dry. Assume 90% humidity at 15°C (saturated water vapor pressure at 15°C=12.8 mm Hg) and calculated the actual partial pressure of O2 in Arcata air.
