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 ["167"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

Plugging in the given values:

Infusion Rate = 1000 mL / 6 hours

Calculating the result:

Infusion Rate ≈ 166.67 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour

A. 1 tablet. B. 1/2 tablet. C. 2 tablets. D. 1 1/2 tablets.

Correct Answer is C

Explanation

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

x tablets / 7.5 mg = 1 tablet / 5 mg

Cross-multiplying:

5x = 7.5

Solving for x:

x = 7.5 / 5

x = 1.5

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets of metolazone.
