A nurse is preparing to administer enoxaparin 40 mg subcutaneous for prevention of deep vein thrombosis. Available is enoxaparin 100 mg/ml. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
To calculate the mL of enoxaparin to administer, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 40 mg, and the concentration is 100 mg/mL:
Volume (mL) = 40 mg / 100 mg/mL = 0.4 mL
So, the nurse should administer 0.4 mL of enoxaparin.

Correct Answer is ["5"]
Explanation
To calculate the volume of megestrol oral suspension (in milliliters, mL) that the nurse should administer, use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 200 mg of megestrol, and the concentration of the oral suspension is 40 mg/mL.
Volume (mL) = 200 mg / 40 mg/mL
Volume (mL) = 5 mL
The nurse should administer 5 mL of megestrol oral suspension to the client.
Correct Answer is ["1.5"]
Explanation
First, we need to calculate the amount of cefazolin 500 mg in milligrams per milliliter (mg/mL) using the information provided:
Cefazolin concentration after reconstitution = 330 mg/mL Amount of cefazolin needed per dose = 500 mg
Now we can calculate the volume (mL) required for the dose:
Volume (mL) = Amount of cefazolin needed per dose / Cefazolin concentration after reconstitution
Volume (mL) = 500 mg / 330 mg/mL ≈ 1.52 mL
Rounded to the nearest tenth, the nurse should administer approximately 1.5 mL of cefazolin per dose.
