A client is receiving alprazolam (Xanax) 0.75 mg PO bid for anxiety. Alprazolam is available in 0.5 mg scored tablets. How many tablets should the nurse administer? (Enter numeric value only.)
The Correct Answer is ["1.5"]
Calculating the Alprazolam Dose
Problem: Administer 0.75 mg of alprazolam PO. The available concentration is 0.5 mg/tablet.
Steps:
Set up a proportion:
We want to find the number of tablets needed.
We know the desired dose (0.75 mg) and the concentration of the medication (0.5 mg/tablet).
Proportion:
x tablets / 0.75 mg = 1 tablet / 0.5 mg
Cross-multiply:
0.5x = 0.75
Solve for x:
x = 0.75 / 0.5
x = 1.5
Answer: The nurse should administer 1.5 tablets of alprazolam per dose.

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 ["2"]
Explanation
To calculate the volume of metoclopramide to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 10 mg / 5 mg/mL
Volume (mL) = 2 mL
Now, we need to convert milliliters to teaspoons.
1 teaspoon ≈ 4.93 mL
To find the number of teaspoons needed:
Number of teaspoons = Volume (mL) / Volume per teaspoon (mL/teaspoon)
Number of teaspoons = 2 mL / 4.93 mL/teaspoon
Number of teaspoons ≈ 0.406 teaspoons
Since we cannot administer a fraction of a teaspoon, we round up to the nearest whole number.
Therefore, the nurse should administer 2 teaspoons of metoclopramide
