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.

Correct Answer is ["2"]

Explanation

To calculate the number of tablets needed, we can set up a proportion:

x tablets / 600 mcg = 1 tablet / 300 mcg

Cross-multiplying:

300x = 600

Solving for x:

x = 600 / 300

x = 2

Therefore, the nurse should administer 2 tablets of levothyroxine.

Correct Answer is ["22"]

Explanation

Calculating the Propofol Infusion Rate

Step 1: Convert weight to kilograms:

198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 90 kg = 720 mcg/minute

Step 3: Calculate the concentration of propofol in the IV solution:

100 mg/50 mL = 2 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute

Then, set up a proportion:

x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL

x mL/hour ≈ 21.6 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.
