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
The patient is ordered to receive 0.5 grams of amoxicillin three times per day, which is equivalent to 500 mg per dose.
The concentration of amoxicillin is 125 mg/5 mL, which means there is 125 mg of amoxicillin in 5 mL of solution. To calculate how many milliliters per dose the nurse should administer, we can use the following formula:
500 mg / 125 mg per 5 mL = X mL X = 20 mL per dose
Amoxicillin is a type of antibiotic that belongs to the penicillin group of drugs. It is used to treat various bacterial infections, such as ear infections, sinus infections, throat infections, urinary tract infections, and skin infections. Amoxicillin works by interfering with the cell wall synthesis of bacteria, causing them to die or stop growing. Amoxicillin can also be used in combination with other drugs to treat stomach ulcers caused by Helicobacter pylori bacteria.
Correct Answer is C
Explanation
To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..
So the nurse should add 250 mL of water to the formula to dilute it to half strength.
