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?
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

Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 30 mg = 1 tablet / 20 mg
Cross-multiplying:
20x = 30
Solving for x:
x = 30 / 20
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 baclofen.

Calculating the Ferrous Fumarate Dose
Problem: Administer ferrous fumarate 3 mg/kg/day PO three times daily to an 88-pound child. The available concentration is 100 mg/5 mL.
Steps:
Convert pounds to kilograms:
88 pounds x (1 kg / 2.20462 pounds) ≈ 39.9 kg
Calculate the daily dose:
3 mg/kg/day x 39.9 kg = 119.7 mg/day
Calculate the dose per administration (TID):
119.7 mg/day / 3 doses = 39.9 mg/dose
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (39.9 mg) and the concentration of the medication (100 mg/5 mL).
Proportion:
x mL / 39.9 mg = 5 mL / 100 mg
Cross-multiply:
100x = 199.5
Solve for x:
x = 199.5 / 100
x ≈ 2
Answer: The child should receive approximately 2 mL of ferrous fumarate oral suspension for each dose.
