A nurse is preparing to administer hydrocortisone 60 mg IV bolus to a child. The amount available is hydrocortisone 100 mg powder. Reconstituting with 2 mL of bacteriostatic water yields hydrocortisone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
To calculate this, divide the dose of hydrocortisone in mg by the concentration of the reconstituted hydrocortisone to find the volume to administer: 60 mg / (50 mg/mL) = 1.2 mL.

Correct Answer is ["0.019"]
Explanation
19,000 mcg of haloperidol is equivalent to 0.019 g.
To calculate this, use the conversion factor that 1 g is equivalent to 1,000,000 mcg. So, 19,000 mcg * (1 g / 1,000,000 mcg) = 0.019 g.
Correct Answer is ["0.2"]
Explanation
To find out how many mL of enoxaparin the nurse should administer, we need to set up a proportion. If 30 mg of enoxaparin is equivalent to 0.3 mL, then 20 mg of enoxaparin is equivalent to x mL.
The proportion can be writen as 30/0.3 = 20/x. Solving for x, we get x = (20 * 0.3) / 30 = 0.2 mL.
