Final answer:
To calculate the infusion rate for normal saline with armione, the patient's weight in pounds is first converted to kilograms. The dosage in mcg per minute is then calculated and converted to grams to match the solution's concentration. The infusion rate of 40 mL/hour is then found by converting mL/minute to mL/hour and rounding to the nearest whole number.
Step-by-step explanation:
The question involves calculating the infusion rate in mL/hour for a client with decompensated heart failure who is receiving an IV fluid of 0.9% normal saline with armione 0.1 g/100 mL at a rate of 8 mcg/kg/minute, with the client's weight being 183 lbs.
First, convert the client's weight from pounds to kilograms: 183 lbs × (1 kg / 2.20462 lbs) = 83.007 kg.
Next, calculate the dose in mcg per minute: 83.007 kg × 8 mcg/kg/minute = 664.056 mcg/minute.
Then, convert mcg to g to match the concentration of the IV solution (1 g = 1,000,000 mcg): 664.056 mcg/minute × (1 g / 1,000,000 mcg) = 0.000664056 g/minute.
To find out how many mL of the IV solution this corresponds to, use the concentration of the IV solution (0.1 g/100 mL): 0.000664056 g × (100 mL / 0.1 g)
= 0.664056 mL/minute.
Finally, convert mL/minute to mL/hour: 0.664056 mL/minute × 60 minutes/hour
= 39.843 mL/hour.
Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 40 mL/hour.
