(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.

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 = $4.598 \times 1000$ = 4598 mL

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

Flow rate = $\frac{\text{Quantity of solution}}{\text{Time period}}$

Here, the Quantity of solution in mL = 4598 mL

Time period = 19 hours

So, Flow rate = $\frac{4598}{19}$

= 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 = $\frac{\text{Quantity of dextrous solution}}{\text{Time period}}$

= $\frac{0.21 \times 4598}{19}$ = 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 $\times$ Drop factor in gtt/mL

= 242 $\times$ 14 = 3388 gtt/hr

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

= $0.21 \times 4598$ = 965.58 mg

Answer from: Quest

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
