Question

1. 500mL of D5W to infuse over 1.5 hours. What rate (mL/hr) should the nurse set the IV pump

2. 500mL of D5W to infuse over 150 minutes. What rate should the nurse set the infusion pump

3. patient is be given 750ml of a D5W over a 6 hour period at 20 gtt/ml. What will be the drop rate

Answer 1

1.Given

Order:D5W

Volume :500ml

Time :1.5hr

Flow rate=Total volume(ml) /Time(hr)

=500/1.5

=333.3 or 333 ml

Ans:The nurse should set the IV pump at 333ml /hr

2.Given

Order:D5W

Volume :500ml

Time:150min

Drop factor :15gtt/ml(standard)

Flow rate = Volume (ml)/Time (min) *drop factor

=500/150*15

=3.3*15

=50

Ans:The nurse should set the IV pump at 50 drops/min

3.Given

Order:D5W

Volume:750ml

Time: 6hr

Drop factor :20gtt/ml

Drop rate=Volume (ml) *Drop factor /Time(hr)*60

=750*20/6*60

=750/6*3 (60 is divisible by 20 ,three times)

=750/18

=41.6 or 42

Ans:The drop rate will be 42 drops/min
