A physician orders the patient methylprednisolone sodium succinate (Solu- Medrol) 80 mg IV every 4 hours for lung inflammation. The single-dose vial yields 1 g/8 mL. How many mL should the nurse administer?
1.08 mL
0.64 mL
1.28 mL
1.38 mL
The Correct Answer is B
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 A
Explanation
To determine the mL per dose of heparin, we can use the following formula:
mL per dose = (total units needed) / (concentration of heparin in units/mL). Substituting the values given in the
Question :.
mL per dose = 10,000 units / 20,000 units/mL = 0.5 mL per dose.
Therefore, the client should receive 0.5 mL per dose of heparin from the vial containing a concentration of 20,000 units/mL.
Correct Answer is C
Explanation
To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:
6 grams ÷ 40 grams = 0.15
Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL
This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:
150 mL x 2 = 300 mL/hr.
