A nurse is preparing to administer cyanocobalamin 100 mcg IM monthly. Available is cyanocobalamin injection 1,000 mcg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.1 mL."]
We need to calculate the volume of the cyanocobalamin injection that contains 100 mcg of the drug: 100 mcg ÷ 1,000 mcg/mL = 0.1 mL
Therefore, the nurse should administer 0.1 mL of cyanocobalamin injection per dose.

Correct Answer is ["200"]
Explanation
To convert the client's weight from kilograms to pounds, you need to multiply the weight in kilograms by the conversion factor of 2.2 lb/kg. So, 91 kg * 2.2 lb/kg = 200.2 lb. When rounded to the nearest whole number, this becomes 200 lb.
Correct Answer is ["0.9 mL"]
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.
