A nurse is preparing to administer phenytoin 200 mg via a gastrostomy tube. Available is phenytoin oral suspension 125 mg/5 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.)

Answer and Explanation

The Correct Answer is ["8"]

To calculate the amount of phenytoin oral suspension 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) = (200 mg / 125 mg/5 mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (200 mg / 125 mg/5 mL) = (200 / 125) 5 = 8

So, the nurse should administer 8 mL of phenytoin oral suspension via the gastrostomy tube.

Correct Answer is ["10"]

Explanation

The nurse needs to administer 775 mg of amoxicillin. The available amoxicillin oral suspension is 400 mg/5 mL, which means there are 400 mg of amoxicillin in every 5 mL of the suspension.

Therefore, for a 775 mg dose, the nurse should administer:

775 mg/(400 mg/5mL) = 9.6875 mL of the suspension

So, the nurse should administer approximately 10 mL (rounded to the nearest whole number).

Correct Answer is ["30"]

Explanation
