Answer 1

18. Ordered dose of Ranitidine is 35mg

Volume of fluid for dissolving - 100ml D5W IV

Time - over 20 minutes

6hourly

Available Ranitidine is 25mg /ml

25mg of Ranitidine is available in 1ml

1mg of Ranitidine will be present in 1/25 ml

Then , 35mg of Ranitidine will be available in 1/25 ×35 ml

= 7/5 ml = 1.4ml

1.4ml of Ranitidine should be taken from the available medicine and add it to the IV bag .

Flow rate - total volume /total time

= 1.4ml / 20 minutes

= 1.4/20 = 14/200

= 7/ 100

= 0.07 ml/ minutes

Frequency - every 6hourly
