1000 ml flask of 0.9% sodium chloride solution is to be slowed down from a 6 hourly rate to an 8 hourly rate what is the new rate in drops per minute assume the use of a standard macro drip giving set

A standard macro drip set delivers 15 drops per milliliter. So, for a 1000 ml flask, the total number of drops would be 15,000 drops (1000 ml * 15 drops/ml). If the current rate is to administer this over 6 hours, then the rate in drops per minute is: Current rate = Total drops / Total time in minutes = 15000 drops / (6 hours * 60 minutes/hour) = 15000 drops / 360 minutes = 41.67 drops/minute Now, if we want to slow this down to an 8 hourly rate, we can calculate the new rate as follows: New rate = Total drops / New total time in minutes = 15000 drops / (8 hours * 60 minutes/hour) = 15000 drops / 480 minutes = 31.25 drops/minute So, the new rate is approximately 31.25 drops per minute. Please note that in practice, drip rates are usually rounded to the nearest whole number, so you might administer approximately 31 drops per minute.
