Question

11) A patient needs 850 mL of a fluid over a 8-hour period. The IV tubing drop factor is 15 gtt/mL. What is the required drip rate in gtt/min needed to deliver the fluid? (Hint: Read p.33 in the 3rd edition of the textbook) 12) A doctor's order is for 7.5 mg of acetaminophen per kg of body weight per dose. For a child who is 35 lb, calculate the number of milligrams needed to be given in a dose. 13) Express car's fuel consumption of 23.3 miles/gal in units of L/100 km, which are used in other countries.

Answer 1

11.Given

Order:IV fluid

Volume:850ml

Time:8 hours

Drop factor:15gtt/ml

Flow rate =Total volume ×drop factor÷total time×60

=850×15÷8×60

=26.5 that is 27gtt/min

Ans:27gtt/min

12.Given

Order:Acetaminophen

Dose:7.5mg/kg

Weight:35lb (35×0.454=15.8 or 16 kg)

As 1kg=7.5mg

Then 16kg=??mg

Cross multiply and divide

=16×7.5÷1

=120mg

Ans:120mg to be administered

13.Given

Fuel consumption :23.3 miles/gal

23.3 miles=37.4km

1 gal=88.2litre

To calculate the fuel consumption divide total litre÷distance

=88.2÷37.4

=2.35L
