The health-care provider prescribes the adjustment of the IV hourly rate based on the nasogastric tube (NGT) output every 4 hour for a client who had abdominal surgery yesterday. From 1200 to 1600, the NGT output was 240 ml, and the IV of Dextrose 5% in 0.45% Sodium chloride (D, 1/2 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, using a whole number.)
