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.)
Answer and Explanation

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 ["0.13"]

Explanation

To calculate the volume of phytonadione (AquaMEPHYTON) 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 micro-grams to milligrams:

250 mcg x (1 mg / 1000 mcg) = 0.25 mg

Then, plug in the values into the formula:

Volume (mL) = 0.25 mg / 2 mg/mL

Calculating the result:

Volume (mL) = 0.125 mL

Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).

Correct Answer is ["33"]

Explanation

Step 1: Calculate the concentration of the medication:

Concentration (mg/mL) = Total Medication (mg) / Total Volume (mL)

Concentration = 2000 mg / 100 mL

Concentration = 20 mg/mL

Step 2: Calculate the infusion rate in mg/minute:

Infusion Rate (mg/minute) = Infusion Rate (mL/hour) x Concentration (mg/mL) x (1 hour / 60 minutes)

Infusion Rate = 100 mL/hour x 20 mg/mL x (1 hour / 60 minutes)

Infusion Rate = 33.33 mg/minute

Rounding to the nearest whole number, the client is receiving 33 mg of medication per minute.
