A nurse is preparing to administer hydrocortisone 150 mg via IV bolus. Available is hydrocortisone 50 mg/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 ["3"]
To calculate the amount of hydrocortisone to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (mg) / Available dose (mg/mL))
Plugging in the given values:
Amount to administer (mL) = (150 mg / 50 mg/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (150 / 50) = 3 mL
So, the nurse should administer 3 mL of hydrocortisone via IV bolus.

Correct Answer is ["0.4"]
Explanation
Given:
Enoxaparin dose: 40 mg
Available concentration: 100 mg/mL
Step 1: Calculate the volume of enoxaparin to be administered in mL
Volume = Enoxaparin dose / Concentration
Volume = 40 mg / 100 mg/mL
Volume = 0.4 mL
Rounding to the nearest tenth:
Volume = 0.4 mL
Therefore, the nurse should administer 0.4 mL of enoxaparin subcutaneously for the prevention of deep vein thrombosis.
Correct Answer is ["0.7"]
Explanation
To calculate the amount of epoetin that the nurse should administer, we can use the following formula:
Amount to administer (mL) = (Desired dose in units) / (Amount of drug in 1 mL)
Given:
Desired dose = 7,000 units
Amount of drug in 1 mL = 10,000 units/mL
Now, let's calculate the amount to administer:
Amount to administer (mL) = 7,000 units / 10,000 units/mL
Amount to administer (mL) = 0.7 mL
Rounding to the nearest tenth, the nurse should administer 0.7 mL of the epoetin.
