A nurse is preparing to administer lidocaine 200 mg IM stat and repeat in 60 min. Lidocaine injection 300 mg/3 mL is available. How many mL should the nurse administer per dose? Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["2"]
To calculate the volume to be administered, the nurse should divide the prescribed dose (200 mg) by the
concentration of the available medication (300 mg/3 mL): 200 mg / (300 mg/3 mL) = 2 mL.

Correct Answer is ["0.5"]
Explanation
To calculate the required mL of heparin injection per dose, we need to use the following formula: mL = (units per dose) ÷ (units per mL)
Substituting the given values in the formula, we get:
mL = (10,000 units) ÷ (20,000 units/mL) mL = 0.5 mL
Correct Answer is ["0.9"]
Explanation
First, you need to convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram, so 99 lb / 2.2 = 45 kg. The dose of morphine is 0.2 mg/kg, so for a client who weighs 45 kg, the dose would be 0.2 mg/kg * 45 kg = 9 mg. To calculate the number of mL the nurse should administer, you need to divide the dose of morphine (9 mg) by the concentration of the morphine injection (10 mg/mL). This gives you 9 mg / (10 mg/mL) = 0.9 mL. When rounded to the nearest tenth, this remains
0.9 mL. So, the nurse should administer 0.9 mL of morphine injection.
