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.

Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.
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.
