(a) The flow rate in units of mL/hr is 242 mL/hr and the flow rate in dextrous per hour is 50.82.

(b) The flow rate in gtt/hr is 3388 gtt/hr.

(c) The dextrous delivered during the 19-hour period is 965.58 mg.

Step-by-step explanation:

We are given that a 21% dextrous solution (21 mg per 100 mL of solution) is given intravenously.

Suppose a total of 4.598 L of the solution is given over a 19-hour period.

Firstly, converting the quantity of solution in mL, we get;

       1 L = 1000 mL

4.598 L = = 4598 mL

(a) The flow rate in units of mL/hr is given by;

        Flow rate  =  

Here, the Quantity of solution in mL = 4598 mL

          Time period = 19 hours

So, Flow rate  =  

                       =  242 mL/hr

Hence, the flow rate in units of mL/hr is 242 mL/hr.

Also, the flow rate in dextrous per hour is given by;

         Flow rate  =  

                           =    = 50.82

Hence, the flow rate in dextrous per hour is 50.82.

(b) It is given that each mL contains 14 drops (the factor is expressed as 14 gtt/mL) and we have to calculate the flow rate in units of gtt/hr.

The flow rate in gtt/hr = Flow rate in units of mL/hr Drop factor in gtt/mL

                                    = 242 14 = 3388 gtt/hr

(c) We have calculated above that the amount of solution given over a 19-hour period is 4598 mL.

Also, a 21% dextrous solution (21 mg per 100 mL of solution) is given intravenously.

So, the dextrous delivered during the 19-hour period = 21% of 4598

                              =   = 965.58 mg
