MD order: dextromethorpan 10 mg q 4 h for a cough
Available: 5g/5 mL
How many teaspoons will be administered per dose?
To determine the number of teaspoons that will be administered per dose, we need to first calculate the dosage in mL.
Given: Available concentration is 5g/5 mL, which is equivalent to 1g/mL.
The order is for 10 mg per dose. Since 1g = 1000mg, we can express 10 mg as 0.01g.
Now, we can calculate the volume in mL:
Volume (mL) = mass (g) / concentration (g/mL)
Volume (mL) = 0.01g / 1g/mL = 0.01 mL
Since there are 5 mL in each teaspoon, we can now determine the number of teaspoons required per dose:
Number of teaspoons per dose = Volume (mL) / 5 mL
Number of teaspoons per dose = 0.01 mL / 5 mL = 0.002 teaspoons
Therefore, approximately 0.002 teaspoons will be administered per dose.
To determine the number of teaspoons that will be administered per dose, we need to convert the given amount of medication (5g/5 mL) into teaspoons for a single dose of dextromethorphan, which is 10 mg.
First, let's convert grams to milligrams:
1 g = 1000 mg
5 g = (5 g) x (1000 mg/1 g) = 5000 mg
Next, we need to calculate the dose per milliliter:
The given amount is 5g/5mL, which can be simplified as 5000 mg/5 mL.
To find the dose per milliliter, we divide the total milligrams (5000 mg) by the total milliliters (5 mL):
5000 mg / 5 mL = 1000 mg/mL
Finally, we need to find the number of teaspoons that will deliver a dose of 10 mg. Since there are 5 mL in a teaspoon, we divide 10 mg by the dose per milliliter (1000 mg/mL) and multiply by the number of milliliters in a teaspoon (5 mL/1 tsp):
(10 mg) x (1 tsp/5 mL) x (1 mL/1000 mg) = 0.002 tsp
So, approximately 0.002 teaspoons (or a very small fraction of a teaspoon) will be administered per dose of dextromethorphan.
