MD order: dextromethorpan 10 mg q 4 h for a cough

Question

Available: 5g/5 mL
How many teaspoons will be administered per dose?

Answer 1

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.
