Final answer:
To find the flow rate of medication for an 8 lb cat, convert the weight to kilograms and then multiply by the dosage rate. The correct flow rate is 10.9 mL/hr.
Step-by-step explanation:
The question involves calculating the flow rate of medication for an 8 lb cat, where the medication dosage is provided in mL/kg per hour. Since we need to work with kilograms, we must first convert the cat's weight from pounds to kilograms. There are 2.2 pounds in a kilogram. So, we calculate the cat's weight in kilograms as 8 lbs divided by 2.2 lbs/kg, which equals approximately 3.636 kilograms.
Next, we multiply the cat's weight in kilograms by the medication dosage to find the flow rate per hour. The equation will look as follows: Flow rate = 3 mL/kg/hour * 3.636 kg, which equals 10.9mL/hr.
Therefore, the correct answer is D. 10.9 mL/hr.
