A client received a prescription for dexamethasone 3 mg/day PO every 8 hours. The medication is available in 1.5 mg/tablet. How many tablets should the nurse administer with each dose?
Answer and Explanation

The Correct Answer is ["2"]

To calculate the number of tablets needed, we can set up a proportion:

x tablets / 3 mg = 1 tablet / 1.5 mg

Cross-multiplying:

1.5x = 3

Solving for x:

x = 3 / 1.5

x = 2

Therefore, the nurse should administer 2 tablets of dexamethasone for each 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 ["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).
