250 mg
500 mg
1000 mg
1500 mg
The Correct Answer is C
To calculate the total amount of medication the client should receive, multiply the volume of the medication by its concentration:

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 C
Explanation
To calculate the amount of diluent that should be added, we need to first calculate the volume of the final solution. .
The final concentration of ceftriaxone should be 600 mg/3 mL, which is the same as 200 mg/mL. .
If we have 1.5 g (or 1500 mg) of ceftriaxone, we can divide this by the desired concentration to get the total volume of the final solution:.
1500 mg ÷ 200 mg/mL = 7.5 mL.
So, the total volume of the final solution should be 7.5 mL. .
To calculate the amount of diluent needed, we need to subtract the volume of the ceftriaxone from the total volume of the final solution:.
7.5 mL - 0.00 mL = 7.5 mL.
Therefore, a nurse should add 7.5 mL of diluent to the vial containing 1.5 g of ceftriaxone to achieve a final concentration of 600 mg/3 mL.
