A client with a diagnosis of hypotension has been ordered a normal saline bolus 250 ml IV to infuse over 15 minutes.
How many ml/hr should you administer?
The Correct Answer is ["1000"]
Step 1 is to convert the time from minutes to hours: 15 min ÷ 60 min/hr = 0.25 hr.
Step 2 is to calculate the rate: 250 ml ÷ 0.25 hr = 1000 ml/hr.
