Question

A 49% dextrose solution (49 mg per 100 ml of solution) is given intravenously. Suppose a total of 1.44 L of the solution is given over a 5-hour period. Complete parts a through c below:

a) 0.0248L
b) 0.1238L
c) 0.3456L
d) (0.4321 L)

Answer 1

The new flow rate will be 10.00 cm³/min when the glucose is replaced by whole blood with a viscosity 2.50 times greater.

Step-by-step explanation:

To determine the new flow rate, we can use the equation:

Flow rate1 = Flow rate2

Given that the flow rate of the glucose solution is 4.00 cm³/min, we can substitute this value into the equation:

4.00 cm³/min = Flow rate2

Since the density of the whole blood is the same, the only factor that changes is the viscosity. If the viscosity of the glucose solution is 1, then the viscosity of the blood is 2.50 times greater. To find the new flow rate, we can multiply the original flow rate by the viscosity ratio:

Flow rate2 = 4.00 cm³/min * 2.50 = 10.00 cm³/min

So, the new flow rate when the glucose is replaced by whole blood with a viscosity 2.50 times greater will be 10.00 cm³/min.
