The healthcare provider prescribes a hydration intravenous (IV) infusion of normal saline to run over 3 hours at 30 mL/hour for a client who is dehydrated and weighs 154 pounds. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numerical value only.)
The Correct Answer is ["30"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
In this case, the volume and the time are given in the prescription, so we just need to plug in the values:
Infusion rate (mL/h) = 30 mL / 1 h
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h

Correct Answer is ["3.5"]
Explanation
To calculate the total volume of diluted medication, we need to use the formula:
Total volume (mL) = Drug volume (mL) + Diluent volume (mL)
First, we need to calculate the drug volume by dividing the dose by the concentration. In this case, 1 mg of hydromorphone is equivalent to 0.5 mL of hydromorphone injection.
Plugging in the given values, we get:
Total volume (mL) = 0.5 mL + 3 mL
Simplifying, we get:
Total volume (mL) = 3.5 mL
Correct Answer is ["29.964"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 165 pounds is equivalent to 74.91 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 74.91 kg x 1,000 mL / 50,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 29.964 mL/h
