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 B
Explanation
To calculate the answer, we can use the following formula:.
(mg of drug required / total mg in vial) x total volume in vial = mL to administer. First, let's convert the dose from mg to g:.
80 mg = 0.08 g.
Next, let's plug in the values:. (0.08 g / 1 g) x 8 mL = 0.64 mL.
Therefore, the nurse should administer 0.64 mL of Solu-Medrol.
Correct Answer is C
Explanation
To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..
So the nurse should add 250 mL of water to the formula to dilute it to half strength.
