What is his drip rate using a 60 gtt/ml drip set (gtt/s)?
What is his rate per hour for the first 12 hours if the Dr. wishes to correct his dehydration in 12 hours (ml/hr)?
What is his rate per hour after dehydration has been corrected (ml/hr)?

Expert Solution

The patient has stopped vomiting but is very dehydrated. He weighs 15 lbs and is diagnosed at 8% dehydration.

15lbs = 6.8kg (1kg = 2.2lbs)

a. Order dose 3 ml/kg/hr.

The dose per hour will be

Then in 24 hours 20.4ml/hr 24 hours = 489.6ml

His hourly rate will be 20.4ml/hr

Answer - Total 489.6ml volume of fluids needed to correct his dehydration status in 24 hours.

b.

Drop factor 60gtt/ml

Drop calculation formula is = (Total volume in ml Time in minutes) drop factor

= (20.4 ml 60 min) 60 gtt/ml = 20.4 drops

Answer - Drip rate will be 20.4 drops/min and 1drops in 3 sec (1gtt/3 sec)

c.

If the doctor wishes to correct his dehydration in 12 hours.

Then the doctor needs to administer 489.6ml in 12 hours.

489.6ml/12 hr = 40.8 ml/hr

Answer - The the hourly rate will be 40.8ml/hr

d.

After dehydration corrected the rate will be reduced to 2 ml/kg/hr

so the hourly rate will be

Answer - After dehydration has been corrected the rate will be 13.6ml/hr
