A child with a seizure disorder receives a prescription for phenytoin 20 mg by mouth every 8 hours. The suspension is available in 125 mg/5 mL. How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8 mL"]
To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (20) / (125 / 5)
Simplifying, we get:
(mL to be administered) = (20) x (5 / 125)
(mL to be administered) = 0.8
Therefore, the nurse should administer 0.8 mL of phenytoin suspension to the child.

Correct Answer is ["0.64 mL"]
Explanation
The correct answer is 0.64 mL. To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (40) / (125 / 2)
Simplifying, we get:
(mL to be administered) = (40) x (2 / 125)
(mL to be administered) = 0.64
Therefore, the nurse should administer 0.64 mL of methylprednisolone IV.
Correct Answer is ["333"]
Explanation
To find the answer, we can use the following formula:
(mg/mL) = (mg of cefazolin) / (mL of solution)
Substituting the given values, we get:
(mg/mL) = (1000) / (3)
Simplifying, we get:
(mg/mL) = 333.333
(rounded mg/mL) = 333
Therefore, after reconstitution, the solution contains 333 mg/mL of cefazolin.
