HACTEHA [7]

P is the perimeter of the triangular base

h is the length of the prism

IRINA_888 [86]

Answer:

50.80 mL/hr

Step-by-step explanation:

The prescription is using kg for the mass unit while the weight use pounds. We have to change the weight unit into kilograms to calculate the dose of the IV infusion. The type of solution should not have any influence on the calculation.

If one kilogram equal to 0.0.453592 pounds, the calculation will be:

14 pounds * (0.0.453592 kg/ pounds) * 8mL/kg/hr=

6.35 kg * 8mL/kg/hr= 50.80 mL/hr
