The nurse is to infuse 1 liter of D10W over 8 hours. What rate will the nurse set the iv pump for??
625 ml/hr
125 ml/hr
250 ml/hr
125 gtt/min
The Correct Answer is B
A. 625 ml/hr: This rate would administer 625 ml per hour, which is too fast for 1 liter over 8 hours.
B. 125 ml/hr: To administer 1 liter (1000 ml) over 8 hours, divide 1000 ml by 8 hours: 1000 ml ÷ 8 hours = 125 ml/hr.
C. 250 ml/hr: This rate would administer 250 ml per hour, which would result in the infusion being completed in 4 hours, not 8.
D. 125 gtt/min: This option is incorrect because it gives a rate in drops per minute, not milliliters per hour.
