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 ["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
Correct Answer is ["160"]
Explanation
Calculate the average hourly NGT output:
Average Hourly NGT Output = Total NGT Output / Number of Hours
Average Hourly NGT Output = 240 mL / 4 hours
Average Hourly NGT Output = 60 mL/hour
Adjust the IV rate:
New IV Rate = Current IV Rate + Average Hourly NGT Output
New IV Rate = 100 mL/hour + 60 mL/hour
New IV Rate = 160 mL/hour
Therefore, the nurse should regulate the IV to deliver 160 mL/hour to replace the fluid loss.
