Answer:
(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 = [tex]4.598 \times 1000[/tex] = 4598 mL
(a) The flow rate in units of mL/hr is given by;
Flow rate = [tex]\frac{\text{Quantity of solution}}{\text{Time period}}[/tex]
Here, the Quantity of solution in mL = 4598 mL
Time period = 19 hours
So, Flow rate = [tex]\frac{4598}{19}[/tex]
= 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 = [tex]\frac{\text{Quantity of dextrous solution}}{\text{Time period}}[/tex]
= [tex]\frac{0.21 \times 4598}{19}[/tex] = 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 [tex]\times[/tex] Drop factor in gtt/mL
= 242 [tex]\times[/tex] 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
= [tex]0.21 \times 4598[/tex] = 965.58 mg
