A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously to a client who weighs 220 lb. Available is enoxaparin 30 mg/0.3 mL. How many mL should the nurse administer? (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 ["1"]
To calculate the correct dose of enoxaparin, we need to follow these steps:
-
Convert pounds to kilograms:
- 220 lb * 0.4536 kg/lb = 99.8 kg
-
Calculate the daily dose in micrograms:
- 1 mg/kg * 99.8 kg = 99.8 mg
-
Determine the volume needed from the available concentration:
- 99.8 mg * (0.3 mL / 30 mg) = 0.998 mL
Therefore, the nurse should administer 1 mL of enoxaparin.
Answer: 1 mL

Answer: 1 mL
Correct Answer is ["0.4"]
Explanation
The nurse should administer 0.4 mL of morphine.
Here's the calculation:
Desired dose: 4 mg
Concentration of available morphine: 10 mg/mL
We can find the volume to administer by dividing the desired dose by the concentration and rounding to one decimal place:
Volume to administer (rounded to one decimal) = Dose / Concentration
= 4 mg / (10 mg/mL)
= 0.4 mL
Therefore, the nurse should administer 0.4 mL of the morphine solution.
