Question

2. the iv is infusing cia gravity flow. calculate the rate in mcgtt/min.

the book says the answer is 90 mcgtt/min but how do you get that?

7. how many mL of iv fluid is the patient receiving in 24 hours? the book says the ans is 2,160 ml. the body weight is 140lb which is 64kg. what would be the next step?

here are the answers to all the questions & the other questions not sure if i need to take an answer from a previous question to complete the others

Answer 1

2.Given

IV fluid:NS:90ml /hour (that is 1hour=90ml)

Then 4 hr=??ml

Cross multiply and divide

=24×90÷1

=360÷1

=2160ml/day

Flow rate=Total volume ×drop factor ÷Time(hr)×60

Here total volume in one hour =90ml

Drop factor:60gtt/min(standard rate for micro drip and mentioned in mc gtt )

=90×60÷1×60(60 and 60 can be cancelled in calculation)

=90

Ans:90mcgtt/min

7.Given

In 1 hour 90 ml NS is infused

So for 1 day (24hour)=2160ml (90×24)

Therefore the patient will receive 2160ml of IV fluid in a day.

1.Given

Medication:Suprax

Order:400mg

Available:500mg/ml ( that is 1ml=500mg)

So 400mg=??ml

cross multiply and divide

=400×1÷500

=400÷500

=0.8

Ans:0.8ml has to be administered

3.Given

Medication:Enoxparin

Dose:1mg/kg

weight: 64kg

To calculate the dose

As 1kg=1mg

Then 64kg=??mg

Cross multiply and divide

=64×1÷1

=64mg

Route:subcutaneous

Frequency:Twice a day

Available:300mg/ml  

So 64mg=??ml

Cross multiply and divide

==64×1÷300

=64÷300

=0.21

Ans:0.21 ml to ne administered
