Pediatric rounding rules

Nursing Students Student Assist

Published

Yes I'm new nursing student and I'm in dosage calculation class. I'm working through some pediatric math involving weight based problems in some text it shows to round KG to nearest tenth and others to nearest hundredth I'm curious which is correct? Also for some pediatric oral liquid medication in some text the final answer is rounded to nearest tenth of an ML and and other text rounded to nearest hundredth of an ML which is correct?

In practice, I complete all calculations and then round the final result. If I am only calculating the weight, I round based on the following:

  • >5 kg: 1 decimal place
  • 1 – 5 kg: 2 decimal places

Rounding volume for medication administration, both enteral and parenteral, I use the following:

  • >1 2mL: 1 decimal place

I was told to round kg to nearest tenth for all weights regardless of age to nearest 10th kg before before proceeding with weight based dose calculation is that correct?

Although I do not use deminsional analysis so maybe that's why we are taught to round kg to nearest tenth on all problems before proceeding

There is no one right, correct answer. Different facilities may have different policies. Do whatever you employer or school instructor wants you to do.

Ok that's I just find it odd there isn't just a standard way it should be done everywhere

This too: You cannot measure oral meds to the 1/100th of an mL. An oral syringe is not calibrated thusly.

Ask your professor what rounding rule they prefer for grading. In real word peds its sometimes guess work. I can't give a baby 2.345 ml of Tylenol I give as close as I can usually 2.4 or as close to between 2.3 or 2.4 as I can depending on the syringe.

Then there's the whole "How do I account for what they just spit at me" factor...

The way we were taught you would administer 2.3ml

So for pediatric patient if an oral liquid medication called for 4.68 ml I would round to nearest tenth but I've seen books put the answer

4.6ml why is that

That could be a huge difference for a NICU baby who is weighed in grams...

If a baby's weight is entered in the system as 2.548 kg, that is what I would use for dosage calculation and then round at the end.
