What is the infusion rate at which the nurse should set the I.V. pump?
A client with heart failure is receiving furosemide (Lasix), 40 mg I.V. The physician orders 40 mEq of potassium chloride in 100 ml of dextrose 5% in water to infuse over 4 hours. The client's most recent serum potassium level is 3.0 mEq/L.

A. 10 ml/hour B. 25 ml/hour C. 50 ml/hour D. 100 ml/hour
The answer to this is letter B. This refers to 25 ml/hour. There is a formula that should be followed in order to reach this conclusion. The total volume divided by the total time of infusion in hours. If we would be using the details that are mentioned above, the formula would read ml/hour100 ml/4 hours = 25 ml/hour.
It is best that this will be learned by the physician immediately so that proper procedures will be done to help improve the patient’s condition. Heart failure is always a life-threatening condition that should be given proper treatment soon otherwise, it can be fatal.
25 ml/hour-rationale: the nurse should use the following formula to determine the infusion rate:total volume (in ml) to be infused/total time of infusion in hours = ml/hour100 ml/4 hours = 25 ml/hour.client needs category: physiological integrityclient needs subcategory: pharmacological and parenteral therapiescognitive level: applicationreference: craven, r.f., and hirnle, c.j. fundamentals of nursing: human health and function, 5th ed. philadelphia: lippincott williams & wilkins, 2007, p. 563.
