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.
