Final answer:
The patient received 12.8 mmols of KCl from the IV solution administered at a rate of 80 mL/hr for 8 hours, given the solution contains 20 mEq KCl per liter.
Explanation:
The solution is composed of D5NS + 20 mEq KCl per liter. To compute the amount of KCl received, we first calculate the total volume of solution given: 80 mL/hr * 8 hrs = 640 mL.
Given that there are 20 mEq of KCl per liter (1000 mL) of the solution, the patient received a total volume that's a fraction of a liter, so we apply a simple proportion to find the milliequivalents of KCl delivered:
(20 mEq KCl / 1000 mL) * 640 mL = 12.8 mEq KCl.
Since mEq directly translates to mmol for KCl (1 mEq KCl = 1 mmol KCl), the patient received 12.8 mmols of KCl.
