A client with pericardial effusion has phrenic nerve compression resulting in recurrent hiccups. The health-care provider prescribes metoclopramide (Reglan) liquid 10 mg PO q 6 hours. Reglan is available as 5 mg/5 ml. A measuring device marked in teaspoons is being used. How many teaspoons should the nurse administer?

Answer and Explanation

The Correct Answer is ["2"]

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 ["1.8"]

Explanation

To calculate the volume of digoxin to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

Plugging in the given values:

Volume (mL) = 0.45 mg / 0.25 mg/mL

Calculating the result:

Volume (mL) = 1.8 mL

Therefore, the nurse should administer 1.8 mL of digoxin.

Correct Answer is ["1.5"]

Explanation

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.
