A 27 % solution ( 27mg per 100 mL of solution) is given intravenously. Suppose a total of 1.638L of the solution is given over a 14-hour period. Complete parts (a) through (c) below. a. What is the flow rate in units of mL/hr? nothing mL/hr (Type an integer or decimal rounded to the nearest thousandth as needed.) What is the flow rate in per hour? nothing mg/hr (Type an integer or decimal rounded to the nearest thousandth as needed.) b. If each mL contains drops (the drop factor is expressed as gtt/mL), what is the flow rate in units of gtt/hr? nothing gtt/hr (Type an integer or decimal rounded to the nearest thousandth as needed.) c. During the -hour period, how much is delivered? nothing mg (Type an integer or decimal rounded to the nearest thousandth as needed.)
