A client receives a prescription for diazepam 12.5 mg IV. The available concentration is 5 mg per ml. How many ml should the nurse administer? (Enter the numerical value only. If rounding is required round to the nearest tenth.)
The Correct Answer is ["2.5"]
To calculate the volume of diazepam to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 12.5 mg / 5 mg/mL
Calculating the result:
Volume (mL) = 2.5 mL
Therefore, the nurse should administer 2.5 mL of diazepam.

Correct Answer is ["3.2"]
Explanation
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
Understanding the Problem:
We need to administer 500 mg of amoxicillin/clavulanate potassium.
The available tablets contain 250 mg amoxicillin and 125 mg clavulanate potassium.
Solution:
Determine the total amount of active ingredients in the available tablets:
250 mg (amoxicillin) + 125 mg (clavulanate potassium) = 375 mg/tablet
Calculate the number of tablets needed:
500 mg (desired dose) / 375 mg/tablet = 1.33 tablets
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets for each dose.
