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.)
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 ["16.8"]
Explanation
To calculate the volume of IV solution needed to dilute the nafcillin, we'll follow these steps:
Step 1: Calculate the total volume of the diluted solution:
Desired Concentration (mg/mL) = Prescribed Dose (mg) / Total Volume (mL)
Rearranging the formula to solve for Total Volume:
Total Volume (mL) = Prescribed Dose (mg) / Desired Concentration (mg/mL)
Total Volume = 800 mg / 40 mg/mL
Total Volume = 20 mL
Step 2: Calculate the volume of nafcillin solution to be added:
Volume of Nafcillin Solution = Prescribed Dose (mg) / Concentration of Nafcillin (mg/mL)
Volume of Nafcillin Solution = 800 mg / 250 mg/mL
Volume of Nafcillin Solution = 3.2 mL
Step 3: Calculate the volume of IV solution needed to dilute:
Volume of IV Solution = Total Volume - Volume of Nafcillin Solution
Volume of IV Solution = 20 mL - 3.2 mL
Volume of IV Solution = 16.8 mL
Therefore, the nurse should add 16.8 mL of IV solution to the volume control device to dilute the nafcillin.
Correct Answer is ["1"]
Explanation
To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 30 mg.
Step 1: Calculate the total number of tablets needed for the new dose:
Total Tablets = Desired Dose (mg) / Tablet Strength (mg)
Total Tablets = 30 mg / 15 mg/tablet
Total Tablets = 2 tablets
Step 2: Determine the number of tablets already administered:
The client already received 1 tablet today.
Step 3: Calculate the number of additional tablets needed:
Additional Tablets = Total Tablets - Tablets Already Administered
Additional Tablets = 2 tablets - 1 tablet
Additional Tablets = 1 tablet
Therefore, the nurse should administer 1 additional tablet of aripiprazole (Abilify) to reach the total newly prescribed dose for the day.
