Answer :
Final answer:
To deliver 2 meq of KCl per hour from a 1-liter IV bag containing 30 meq of KCl, the fluid rate should be set to 66.67 mL/hour.
Explanation:
The student is asking how to calculate the infusion rate that would deliver 2 meq of KCl (potassium chloride) per hour when 30 meq of KCl is added to a 1-liter bag of normal saline. To give the patient 2 meq KCl/hour using a 1-liter IV bag that contains a total of 30 meq of KCl, you would need to deliver 1/15th of the bag per hour, since 30 meq divided by 2 meq/hour equals 15 hours for the total bag to be infused.
Therefore, to provide 2 meq KCl per hour, you would set the IV fluid rate to 66.67 mL/hour (1000 mL / 15 hours). Therefore, the fluid rate would be 66.67 ml/hour. This calculation ensures the patient receives the prescribed amount of potassium chloride accurately.
