An 88 pound child with iron deficiency anemia has been prescribed ferrous fumarate 3 mg/kg/day PO three times daily. The medication is available in oral suspension of 100 mg/5 ml. The nurse is instructing the mother in measuring the correct dose. How many ml should the child receive for each dose?
The Correct Answer is ["2"]
Calculating the Ferrous Fumarate Dose
Problem: Administer ferrous fumarate 3 mg/kg/day PO three times daily to an 88-pound child. The available concentration is 100 mg/5 mL.
Steps:
Convert pounds to kilograms:
88 pounds x (1 kg / 2.20462 pounds) ≈ 39.9 kg
Calculate the daily dose:
3 mg/kg/day x 39.9 kg = 119.7 mg/day
Calculate the dose per administration (TID):
119.7 mg/day / 3 doses = 39.9 mg/dose
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (39.9 mg) and the concentration of the medication (100 mg/5 mL).
Proportion:
x mL / 39.9 mg = 5 mL / 100 mg
Cross-multiply:
100x = 199.5
Solve for x:
x = 199.5 / 100
x ≈ 2
Answer: The child should receive approximately 2 mL of ferrous fumarate oral suspension for each dose.

Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 30 mg = 1 tablet / 20 mg
Cross-multiplying:
20x = 30
Solving for x:
x = 30 / 20
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of baclofen.
Correct Answer is C
Explanation
To calculate the volume of amoxicillin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 500 mg / 125 mg/mL
Calculating the result:
Volume (mL) = 20 mL
Therefore, the nurse should administer 20 mL of amoxicillin.
The correct answer is C. 20 ml.
