Morphine sulfate 10 mg IM is ordered. Morphine sulfate 5 mg/mL is available. What volume (mL) should be administered?
0.5 mL
1 mL
1.5 mL
2 mL
The Correct Answer is D
To calculate the volume to be administered, divide the ordered dose by the available concentration:
10 mg ÷ 5 mg/mL = 2 mL
The nurse should administer 2 mL of morphine sulfate 5 mg/mL to give a total dose of 10 mg.

Correct Answer is B
Explanation
Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)
Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)
Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL
So, the nurse should administer 64 mL to the patient.
The correct answer is B. 64 mL.
The correct answer is B. 64 mL.
Correct Answer is C
Explanation
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.
