Correct Answer is C

Explanation

To calculate the dose that the child receives, we need to first convert the volume of the suspension from teaspoons to milliliters. One teaspoon is equal to 5 milliliters, so 2 teaspoons is equal to 10 milliliters. Then, we can use the concentration of the suspension to find the amount of cefuroxime in 10 milliliters. The concentration is 25 mg in 2 mL, or 12.5 mg in 1 mL. Therefore, the amount of cefuroxime in 10 mL is:

10 mL × 12.5 mg/mL = 125 mg

Therefore, the child receives 125 mg of cefuroxime once a day orally.

A. 0.5 mg/hr B. 30 mg/hr C. 60 mg/hr D. 145 mg/hr

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.
