The health care provider prescribed the adjustment of the IV hourly rate based on the nasogastric tube (NGT) output q4h (every 4 hours) for a client who had abdominal surgery yesterday. From 12:00pm to 4:00pm the NGT output was 240ml and the IV was infused at a rate of 100ml/hour. at 4:00pm the nurse should regulate the IV to deliver how many ml/hour to replace this fluid loss? (numerical value only)

160

To solve this problem, we need to calculate the difference between the NGT output and the IV fluid rate for the given time period (12:00pm to 4:00pm), and then adjust the IV hourly rate accordingly.

Step 1: Calculate the fluid loss via NGT output
The NGT output from 12:00pm to 4:00pm is 240 ml.

Step 2: Determine the adjustment needed in IV hourly rate
To replace the fluid loss, we need to adjust the IV hourly rate accordingly. The adjustment is calculated by subtracting the NGT output from the current IV fluid rate.

Current IV fluid rate: 100 ml/hour

Adjustment = NGT output - IV fluid rate
= 240 ml - 100 ml
= 140 ml/hour

Step 3: Calculate the new IV hourly rate
To get the new IV hourly rate, we add the adjustment calculated in Step 2 to the current IV fluid rate.

New IV hourly rate = Current IV fluid rate + Adjustment
= 100 ml/hour + 140 ml/hour
= 240 ml/hour

Therefore, at 4:00pm, the nurse should regulate the IV to deliver a rate of 240 ml/hour to replace the fluid loss.

The numerical value for the answer is 240.

2.4 ml/hr
