A nurse is preparing to administer ceftriaxone 250 mg IM to an adult client who has a gonococcal infection. The label on the vial indicates to reconstitute each vial with sterile water 2.1 mL to yield ceftriaxone 350 mg/mL. How many mL of the reconstituted medication should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.71"]
To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.
The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.
The desired dose is 250 mg.
So, you can use the following formula:
Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)
Volume to administer (mL) = 250 mg / 350 mg/mL
Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)
Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.

Explanation
To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.
The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.
The desired dose is 250 mg.
So, you can use the following formula:
Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)
Volume to administer (mL) = 250 mg / 350 mg/mL
Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)
Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.
Correct Answer is ["2"]
Explanation
To determine how many tablets of sotalol the nurse should administer with each dose, you can use the following calculation:
Total daily dose / Number of doses per day = Dose per administration
In this case, the total daily dose is 320 mg, and it's divided into two doses per day.
320 mg / 2 doses = 160 mg per administration
Now, you know that the nurse should administer 160 mg of sotalol with each dose. The available tablets are 80 mg each, so you can calculate how many tablets are needed:
Dose per administration / Tablet strength = Number of tablets
160 mg / 80 mg/tablet = 2 tablets
Therefore, the nurse should administer 2 tablets of sotalol with each dose.
