A nurse is preparing to administer phenytoin 100 mg oral suspension PO to a school-age child who has epilepsy. According to the medication label. What is the total dose of the container? (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 ["100"]
Identify the given information:
Concentration of phenytoin oral suspension: 100 mg/4 mL
Volume of the container: 4 mL
Calculate the total dose of phenytoin:
Total dose = Concentration (mg/mL) x Volume (mL)
Substitute the values:
Total dose = 100 mg/4 mL x 4 mL
Calculate the result:
Total dose = 100 mg

Correct Answer is ["13"]
Explanation
Identify the given information:
Dose of acetaminophen: 400 mg
Concentration of acetaminophen liquid: 160 mg/5 mL
Calculate the volume of acetaminophen liquid to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 400 mg / (160 mg/5 mL)
Volume = 12.5 mL
Round the answer to the nearest whole number:
Volume ≈ 13 mL
Correct Answer is ["0.3"]
Explanation
Given:
Desired dose: Penicillin G benzathine 200,000 units IM
Available concentration: Penicillin G benzathine injection 600,000 units/mL
To find:
Volume to administer (in mL)
Step 1: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 2: Substitute the values
Plugging in the given values, we get:
(200,000 units) / (600,000 units/mL) = Volume to administer
Step 3: Simplify
To simplify, we can invert the denominator and multiply:
(200,000 units) * (1 mL / 600,000 units) = Volume to administer
The "units" cancel out, leaving us with:
(200,000 * 1 mL) / 600,000 = Volume to administer
Step 4: Calculate
Performing the multiplication and division, we get:
200,000 mL / 600,000 = Volume to administer
0.33 mL = Volume to administer
Step 5: Round to the nearest whole number
Since the question asks for the volume rounded to the nearest whole number, we round 0.3.
