The healthcare provider prescribes the adjustment of the IV hourly rate based on
the nasogastric tube (NGT) output q4h for a client who had abdominal surgery
yesterday. From 1200 to 1600, the NGT output was 240 ml, and the IV of D5W
0.45% NS was infused at a rate of 100 ml/hour. At 1600 the nurse should
regulate the IV to deliver how many ml/hour to replace this fluid loss? (Enter
numeric value only.)

Correct Responses
▪ 160
To calculate the hourly rate of IV fluid replacement based on the last 4 hours of
NGT output, the nurse should calculate an average hourly output by dividing 240
ml by 4 hours = 60 ml NGT output q1h. The nurse should then add the 60 ml loss
per hour to the present infusion rate of 100 ml/hr, totaling an infusion rate of 160
ml/hour for the next 4 hours.
