What is the dose for a 180-lb patient?c. A physician has ordered 0.50 mg of atropine, intramuscularly. If atropine were available as 0.10 mg /mL of solution, how many milliliters would you need to give?d. During surgery, a patient receives 5.0 pt of plasma. How many milliliters of plasma were given?The amount of calcium in physiologic fluids can be determined by a complexometric titration with EDTA. In one such analysis, a 0.100-mL sample of blood serum was made basic by adding 2 drops of NaOH and titrated with 0.001 M EDTA, requiring 0.238 mL to reach the end point. Report the concentration of calcium in the sample as miligrams of Ca per 100 mL. (Ca = 40.078 amu).4 How do I convert from DPM to picomoles per milligram of protein (pmol/mg)?
