First, we need to convert the weight of the child from pounds to kilograms. We know that 1 lb is equal to 0.4536 kg. Therefore, the child's weight in kilograms is:
71.1 lb * 0.4536 kg/lb = 32.2 kg.
Next, we need to calculate the total dosage of Medrol that the child should receive. We can do this by multiplying the child's weight by the dosage ordered by the nurse practitioner:
32.2 kg * 1.6 mg/kg = 51.52 mg.
Since the stock of Medrol is in milligrams per milliliter, we can use this information to calculate the volume of Medrol that the nurse needs to administer. We can do this by dividing the total dosage by the concentration of the stock:
51.52 mg / 20 mg/mL = 2.576 mL.
Rounding to two significant figures, the nurse should administer 2.6 mL of Medrol to the child.
A nurse practitioner orders Medrol to be given 1.6 mg/ kg of body weight. Medrol is an anti-inflammatory administered as an intramuscular injection. If a child weighs 71.1 lb and the stock of Medrol is 20. mg/mL, how many milliliters does the nurse administer to the child?
Express your answer to two significant figures and include the appropriate units.
