Question

1) An IV solution of 270 mL at a drip rate of 30 gtt/min using a tubing factor of 15 gtt/mL has been ordered to be initiated at 0615. Calculate the infusion time. (Round your answer to the nearest tenth of an hour.)

2) The order reads 530 mL over 22 hours. Calculate the infusion rate. (Round your answer to the nearest tenth.)

= _____________

Answer 1

ANSWER :

1) 270ml at drip rate 30gtt/min

Tubing factor = 15gtt/ml

15 gtt -----------> 1ml

30 gtt ------------>?

= 30 ÷ 15 = 2ml

So , infusion rate is 2ml/min

2ml ------------> 1min

270ml ---------> ?

= (270×1) ÷ 2 = 135 min = 2.25 hours

So, the infusion time is 2.25 hrs

2)Order 530 ml over 22hrs

22hrs = 22×60 = 1320 min

1320 min --------> 530ml

1min -------------> ??

= (530 × 1) ÷ 1320 = 0.4ml/min

So, the infusion rate is 0.4ml/min
