Question

The patient has stopped vomiting but is very dehydrated. The Dr. orders fluid therapy for him.. He weighs 15 lbs and is diagnosed at 8% dehydration.

I did the first three but I don't know if correct and then got lost

a. What is the total volume of fluids needed to correct his dehydration status in 24 hours? Use a maintenance rate of 3 ml/kg/hr.

15Ibs=6.8kg

Maintenance = 6.8kg x 3ml/kg/hr = 20.4ml/hr = 20ml/hr

Dehydration volume = 6.5kg x 0.08 = 0.544kg x 1000 = 544ml

20ml/hr + 544ml = 564ml over 24hours

b. What is his hourly rate (ml/hr)?

6.8kg x 3ml/kg/hr = =20.4ml/hr = 20ml/hr

c. What is his drip rate using a 60 gtt/ml drip set (gtt/s)?

(20ml/hr) x (1hr/60min) x (1min/60sec) x (60gtt/1ml) = 1200/3600 = (0.33gtt/sec)x3 = 1gtt/3s

d. What is his rate per hour for the first 12 hours if the Dr. wishes to correct his dehydration in 12 hours (ml/hr)?

e. What is his rate per hour after dehydration has been corrected (ml/hr)?

Answer 1

The patient has stopped vomiting but is very dehydrated. Dr. orders fluid therapy for him.. He weighs 15 lbs and is diagnosed at 8% dehydration.

A.

Fluid ordered at a rate of 3 ml/kg/hr

Patients weights 15lbs = 6.8kg

So,

So, in 24 hour

Answer - in 24-hour patient required 489 ml of fluid.

B.

Hourly rate is 20.4 ml/hr

C.

Drop factor 60gtt/ml

Formula to calculate drop =( Total Volume in ml Time in minutes) Drop factor

Answer - 20gtt/min or 1 drop in 3 seconds.

D.

if the Dr. wishes to correct his dehydration in 12 hours

Total of 489 ml was decided ti give in 24 hours but in 12 hours

Then

Answer - 40.7ml/hr
