ANSWERS

1.  100 ml X 10 gtts per ml/30 min = 1000 gtts / 30 min = 33 gtts per min

2.  1000 ml X 15 gtts per ml/540 min = 15000 gtts/ 540 min = 28 gtts per min

3.  1500 ml X 10 gtts per ml/240 min = 15000 gtts / 240 min = 63 gtts per min

4.  2000 ml X 10 gtts per ml/300 min = 20000 gtts / 300 min = 67 gtts per min

5.  100 ml X 15 gtts per ml/60 min = 1500 gtts / 60 min = 25 gtts per min

6.  800 ml X 15 gtts per ml/180 min = 12000 gtts / 180 min = 67 gtts per min

7.  50 ml X 15 gtts per ml/30 min = 750 gtts / 30 min = 25 gtts per min

8.  700 units per hr X 1ml/100 units = 7ml per hr

9.  1000 ml/24 hr X 1 hr/60min X 60 gtts/ml = 42 gtts per min

10. 2mg/ 1 min X 250 ml/400mg X 60 min/1 hr = 75 ml per hr
