A child is to receive vancomycin 40 mg/kg intravenously one hour before a scheduled procedure. The child weighs 44 pounds. How many mg of the medication should the nurse administer? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["800"]

To find the answer, we can use the following steps:

- Convert the child's weight from pounds to kilograms by dividing by 2.2

- Multiply the weight in kilograms by the dosage in mg/kg

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (44) / (2.2) = 20

- (dose in mg) = (40) x (20) = 800

- (rounded dose in mg) = 800

Therefore, the nurse should administer 800 mg of vancomycin to the child.

Correct Answer is ["180"]

Explanation

To find the answer, we can use the following steps:

- Convert the client's weight from pounds to kilograms by dividing by 2.2

- Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60

- Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (165) / (2.2) = 75 kg

- (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour

- (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour

- (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour

Therefore, the nurse should set the infusion pump to deliver 180 mL/hour of dobutamine hydrochloride in D5W.

Correct Answer is ["1"]

Explanation

First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.

Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:

Amount of solution= amount of water + amount of warfarin

Substituting the given values, we get:

Amount of solution = 2.7 + 5 =7.7 mL

Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:

mL of solution = mg of warfarin/ concentration of warfarin

Substituting the given values, we get:

mL of solution = 2/2 = 1 mL

Therefore, the nurse should administer 1 mL of solution to the patient.
