PEDIATRIC MATH

I'm needing help with a pediatric dosage calculation. Here's the question the doctor orders Tylenol 15mg/kg for a 8lb 3 oz infant available amount of medication is 160mg/5ml how many ml of medication will the child receive? And with it being an infant would you round the final answer to the hundredths place? Because I've been reading that with pediatric dosage amounts greater than 1 ml you round to the hundredths place but in other places I've seen the amount for pediatric doses rounded to the tenth ml

In practice, whether you round the volume to be administered to 0.1 mL or 0.01 mL is going to depend on the graduation marks of the syringe that you have available, and not whether the patient is an infant or pediatric patient. During your course work your instructor should tell you whether you should round to the nearest 0.1 mL or 0.01 mL.

In my current practice I have the following syringes available for the administration of enteral medications: 1 mL, graduated in 0.01 mL increments; 3 mL, graduated in 0.1 mL increments; 6 mL and 12 mL, graduated in 0.2 mL increments; and 20 mL and 60 mL, graduated in 1 mL increments. When I calculate the volume of medication to administer I complete all calculations, and then round my final volume based upon the syringe I am going to use.

When using the 1 mL syringe, you can accurately dispense a volume to the nearest 0.01 mL. When using the 3 mL syringe, you can accurately dispense a volume to the nearest 0.01 mL, and closely estimate a volume to the closest 0.05 mL. When using the 6 mL or 12 mL syringe, you can accurately dispense a volume to the nearest 0.2 mL, and closely estimate a volume to the closest 0.1 mL. And when using the 20 mL or 60 mL syringe, you can accurately dispense a volume to the nearest 1 mL, and closely estimate a volume to the closest 0.5 mL.

In the example you provided:

1. How many kg does the patient weigh?

2. How many mg acetaminophen will you administer?

3. What is the calculated volume to be administered?

4. What is the actual volume to be administered?

5. Which syringe would you use to do so?

So for that question what amount of medication would you administer?

  • Author

What would your answer be for the question?

Okay, you've asked this same question in three different threads and have received a lot of appropriate responses. What gives? If you're having a difference of opinion with your instructor, you should be asking these questions there.
