Primaxin (imipenem) 275 mg IM is ordered. Primaxin 500 mg/2 mL is available. How many milliliters should the nurse administer to the patient?
Round to the nearest tenth.
1 mL
1.1 mL
3.6 mL
11 mL
The Correct Answer is B
We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.
275/X = 500/2.
Cross-multiplying, we get:. 500X = 275 x 2.
X = (275 x 2)/500. X = 1.1 mL.
Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.

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.
