Answer 1

18. Answer ; 21 gtt / min

Reason ; Here the total volume is 250 ml and the given drop factor is 10 gtt / ml
The given time period is 2 hour.

According to the basic formula for IV calculation,
250 x 10 / 2 x 60 = 2500 / 120
= 20. 83
Hence the flow rate would be of 21 drops per minute to this drug.

19. Answer ;

Here the ordered dose with available solution is 100 ml
And the drop factor is 10 drops per ml
The infusion time is one hour.

Therefore the pump need to be set at 100 x 10 = 1000 ml per hour.

Hence the answer would be 1000 ml / hr
