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 ["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.

Correct Answer is ["2"]

Explanation

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

x tablets / 1000 mg = 1 tablet / 500 mg

Cross-multiplying:

500x = 1000

Solving for x:

x = 1000 / 500

x = 2

Therefore, the nurse should administer 2 tablets of metformin for each dose.
