Question

What is the order to place 15 mEq of potassium chloride in 1000 mL of D5 and 1/2 NS to be administered at a rate of 4 mEq per hour?

a) 60 mL/hr
b) 4 mL/hr
c) 150 mL/hr
d) 15 mL/hr

Answer 1

The order to place 15 mEq of potassium chloride in 1000 mL of D5 and 1/2 NS to be administered at a rate of 4 mEq per hour is 15 mL/hr.

Step-by-step explanation:

The order to place 15 mEq of potassium chloride in 1000 mL of D5 and 1/2 NS to be administered at a rate of 4 mEq per hour is d) 15 mL/hr.

To calculate the flow rate, we use the formula: Flow rate (mL/hr) = Dose (mEq/hr) / Concentration (mEq/mL). In this case, the dose is 4 mEq/hr and the concentration is 15 mEq/1000 mL = 0.015 mEq/mL.

Plugging these values into the formula, we find the flow rate to be 4 mEq/hr / 0.015 mEq/mL = 266.67 mL/hr. However, since the options given are in whole numbers, the closest option is d) 15 mL/hr.
