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 D
Explanation
A. 0.04 mg
-
This is far too small.
-
It might come from a miscalculation involving the concentration (1 mg/mL) and volume (5 mL), but incorrectly dividing again by 100.
-
Not clinically reasonable because the patient would barely receive any drug.
B. 0.25 mg
-
This is also incorrect.
-
It could result from mistakenly dividing 5 mg by 20 minutes instead of 2 minutes.
-
Again, far below the actual ordered rate.
C. 3.75 mg
-
This is incorrect but closer.
-
It might come from a misstep like subtracting 1.25 mg from the correct answer (2.5 mg) or misusing the concentration.
-
Still not the right calculation.
D. 2.5 mg
-
Correct answer.
-
Direct calculation: 5 mg ÷ 2 minutes = 2.5 mg/min.
-
Matches the ordered dose and administration time.
Correct Answer is B
Explanation
The correct answer is choice B. 2 bottles. To find the number of bottles required, use the formula: (dose x duration) / (bottle size x tablet strength). In this case, (600 mg/day x 7 days) / (7 tablets/bottle x 300 mg/tablet) = 2 bottles.
