A client receives a prescription for tobramycin sulfate (Nebcin) 0.128 grams IV every 8 hours. Tobramycin is available in liquid concentration of 40 mg/ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["3.2"]

To calculate the volume of tobramycin sulfate to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

First, let's convert the desired dose from grams to milligrams:

0.128 grams x 1000 mg/gram = 128 mg

Then, plug in the values into the formula:

Volume (mL) = 128 mg / 40 mg/mL

Calculating the result:

Volume (mL) = 3.2 mL

Therefore, the nurse should administer 3.2 mL of tobramycin sulfate.
