Introduction

Medication administration requires precise calculations to ensure patient safety. This paper will demonstrate each step of the calculation process for five different medication-related questions, providing a clear understanding of how to derive correct infusion rates, doses, and settings based on the given data.

Question 1: Norepinephrine IV infusion rate

The order specifies administering norepinephrine at 4 mcg/kg/hr for a client weighing 200 pounds. First, convert pounds to kilograms:

  • 200 lbs ÷ 2.2 = 90.91 kg

Next, determine the total hourly dose in micrograms:

  • 4 mcg/kg/hr × 90.91 kg ≈ 363.64 mcg/hr

Using the medication label, the concentration of norepinephrine is typically provided as a solution with a known dosage, for example, 4 mg in 250 mL. To find the mL/hr, convert the dose to mg/hr:

  • 363.64 mcg/hr = 0.36364 mg/hr

If the label states that 4 mg is diluted in 250 mL, then the infusion rate (mL/hr) is:

  • (0.36364 mg/hr ÷ 4 mg) × 250 mL = 22.86 mL/hr

Thus, the infusion pump should be set to approximately 23 mL/hr.

Question 2: Max dose of cephalexin for 44 lb child

Convert weight to kg:

  • 44 lb ÷ 2.2 = 20 kg

The maximum recommended daily dose per kg is 100 mg/kg/day. Therefore, total daily maximum dose:

  • 100 mg/kg × 20 kg = 2000 mg/day

Divided into 4 doses:

  • 2000 mg ÷ 4 = 500 mg

Deeply rounding to the nearest whole number, the maximum single dose is 500 mg.

Question 3: Max dose for a 100 lb child

Convert weight to kg:

  • 100 lb ÷ 2.2 ≈ 45.45 kg

The higher end of the recommended dose range is 60 mg/kg/day:

  • 60 mg/kg × 45.45 kg ≈ 2727 mg/day

Divided by 6 doses:

  • 2727 mg ÷ 6 ≈ 454.5 mg

Rounded to the nearest whole number, the maximum single dose is approximately 455 mg.

Question 4: Ondansetron IV infusion rate

The order states 10 mg IV every 6 hours, and available is 8 mg in 100 mL NS to infuse over 30 minutes. To prepare infusion:

  • Calculate infusion rate in mL/hr:

Since the infusion duration is 30 minutes (0.5 hours), the rate is:

  • (100 mL ÷ 0.5 hours) = 200 mL/hr

Thus, the IV pump must be set to 200 mL/hr.

Question 5: Infusing 0.9% NaCl over 30 minutes

The order is 250 mL over 30 min:

  • First, convert 30 minutes to hours: 30 min = 0.5 hours

Calculate the infusion rate in mL/hr:

  • 250 mL ÷ 0.5 hours = 500 mL/hr

Therefore, the pump should be set to 500 mL/hr.

Conclusion

Accurate medication calculations are vital in clinical practice to prevent medication errors and ensure effective treatment. This exercise demonstrated step-by-step calculations for infusion rates, doses, and pump settings based on different medication orders, highlighting the importance of unit conversions, dose calculations, and proper infusion rate determinations.
