Why do you receive potassium intravenously? The order reads to administer potassium 40 mEq over 4 hours. Pharmacy sends up the potassium solution in a total of 480 ml of D5W. What rate will you set on the intravenous pump?
Answers
Potassium is given intravenously in severe hypokalemia. Hypokalemia is a condition where body potassium level decreases below 3.5 mg/dl.
Reason for Hypokalemia -
1. severe diarrhea and vomiting
2. Excess use of diuretics
3. Dialysis
4. Hypomagnesemia
5. Low intake of Pottasium rich diet
The order reads to administer potassium 40 mEq for over 4 hours.
The pharmacy sends up the potassium solution in a total of 480 ml of D5W.
So, we have to administer 480ml in 4 hours(240 minutes).
Answer - You will set the pump at 120 ml/hr or 2ml/min.
480ml = 240min = 2ml/min480ml = 4hr = 120ml/min
