Correct Answer is B

Explanation

To calculate the dose of dobutamine in mg/hr, we need to convert the patient's weight from pounds (lb) to kilograms (kg) and then use the ordered dose of 10 mcg/kg/min.

1 lb = 0.453592 kg (rounded to 6 decimal places) Patient's weight in kg = 110 lb x 0.453592 kg/lb

Patient's weight in kg = 49.89512 kg (rounded to 5 decimal places)

Now we can calculate the dose of dobutamine in mg/hr using the following formula:

Dose (in mg/hr) = Weight (in kg) x Dose (in mcg/kg/min) x 60 (to convert minutes to hours) / 1000 (to convert mcg to mg)

Dose (in mg/hr) = 49.89512 kg x 10 mcg/kg/min x 60 / 1000

Dose (in mg/hr) = 29.937072 mg/hr (rounded to 3 decimal places)

Therefore, the patient should receive a dose of approximately 29.9 mg/hr of dobutamine.
