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

Answer and Explanation

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 B

Explanation

The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.

A. 0.65 mL/hr B. 9.6 mL/hr C. 10.1 mL/hr D. 14.8 mL/hr

Correct Answer is C

Explanation

We can use the following formula to calculate the infusion rate:

Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg

First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg

125,000 mcg/500 mL = 250 mcg/mL

Now we can plug in the values we have into the formula:

Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr

Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.

Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.
