The doctor orders a sliding scale of potassium chloride (KCL) administration:

- If the potassium (K) level is above 4 mEq, do not administer KCL.
- If the K level is 3.8 to 4 mEq, administer 10 mEq of KCL added to 100 mL of NS infused over 1 hour.
- If the K level is 3.6 to 3.8 mEq, administer 20 mEq of KCL added to 200 mL of NS infused over 2 hours.
- If the K level is below 3.6, administer 40 mEq of KCL added to 500 mL of NS infused over 4 hours.

If the K level is 3.2 mEq, calculate the flow rate in mL/hr.

a. 110 mL/hr
b. 120 mL/hr
c. 25 mL/hr
d. 125 mL/hr
e. 100 mL/hr
