Correct Answer is B

Explanation

The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:

Amount of solution = Amount of medication needed / Concentration of medication in the solution.

In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:

Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL

Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.

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.
