Cefuroxime is available as a suspension of 25 mg in 2 mL. A mother informs a nurse that she gives her child 2 tsp of the suspension once a day orally.
What is the dose that the child receives?
62.5 mg
100 mg
125 mg
250 mg
The Correct Answer is C
To calculate the dose that the child receives, we need to first convert the volume of the suspension from teaspoons to milliliters. One teaspoon is equal to 5 milliliters, so 2 teaspoons is equal to 10 milliliters. Then, we can use the concentration of the suspension to find the amount of cefuroxime in 10 milliliters. The concentration is 25 mg in 2 mL, or 12.5 mg in 1 mL. Therefore, the amount of cefuroxime in 10 mL is:
10 mL × 12.5 mg/mL = 125 mg
Therefore, the child receives 125 mg of cefuroxime once a day orally.

Correct Answer is D
Explanation
To calculate the amount of magnesium sulfate to be added to the normal saline, we can use the formula:
Concentration = Dose / Volume Plugging in the given values, we get:
Concentration = 2 g / 50 mL Simplifying, we get:
Concentration = 0.04 g/mL
To find the amount of magnesium sulfate needed for 1000 mL of normal saline, we can multiply the concentration by the volume:
Amount = Concentration × Volume Amount = 0.04 g/mL × 1000 mL Amount = 40 g
Therefore, 40 g of magnesium sulfate must be added to 1000 mL of normal saline to provide the ordered infusion.
Correct Answer is C
Explanation
A. 5ML: One tablespoon is equivalent to 15 milliliters, so 5 milliliters is too little for the prescribed dose.
B. 10ML: This amount is also insufficient, as it does not match the standard conversion of one tablespoon to milliliters.
C. 15ML: This is the correct conversion, as one tablespoon is equal to 15 milliliters.
D. 30ML: This amount is double the correct dose, which could lead to overmedication and potential side effects.
