Answer 1

1.Given

Medication :Magnesium sulphate

Dose:500mg

Time:1 hour

Drop factor :15 (standard)

Available 4gm /250ml (5gm=4000mg)

So 500mg=??

=31.25 ml or 31 ml (500×250÷4000)

Flow rate =Total volume÷Time (min)×drop factor

=31÷60×15

=7.75 i.e. 8 gtt /min

8 gtt/min

Ans:31ml/hour to transfuse a dose of 500mg hourly

2.Flow rate:Total volume×Drop factor÷Time×60

Total volume:1000ml

Drop factor:15

Time:15 hours

=1000×15÷15×60

=16.6 ( 17 drops /min)

To calculate for 1 hour

When 1000ml=15hours

Then 1hour=??

Cross multiply and divide

=1000÷15

=66.6

Ans:67ml /hour

3.Given

Medication :Pepcid

Dose:20mg

Route:IV

Time:30minute (0.5hr)

Frequency :Twice a day

Available :20mg/100ml

Flow rate:Volume ÷Time (hr)

=100÷0.5

=20ml/hr

4.Given 0.5mg/hr

Available :10mg/100ml

So 0.5 mg=??

=5ml (0.5×100÷10)

Ans:5ml/hr
