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.)
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 ["125"]
Explanation
To calculate the rate at which the nurse should set the IV pump to deliver dextrose 5% in 0.45% sodium chloride over 24 hours, we can use the following steps:
Given:
Total IV fluid volume: 3 L
Infusion duration: 24 hours
Step 1: Convert the total IV fluid volume from liters (L) to milliliters (mL)
Total volume = 3 L × 1000 mL/L
Total volume = 3000 mL
Step 2: Calculate the rate of infusion per hour
Rate = Total volume / Infusion duration
Rate = 3000 mL / 24 hr
Rate ≈ 125 mL/hr
Rounding to the nearest whole number:
Rate ≈ 125 mL/hr
Therefore, the nurse should set the IV pump to deliver approximately 125 mL/hr for the infusion of dextrose 5% in 0.45% sodium chloride over 24 hours.
