A patient is prescribed 6 mg of cough medication. The label on the prescription says there are 2 mg per 4 mL. How many teaspoons of cough medication does the patient need to take?
show all steps
First, we need to find how many mL are needed for 6 mg of cough medication. Since the ratio is 2 mg per 4 mL, we can set up a proportion:
2 mg / 4 mL = 6 mg / x mL
Cross multiplying, we get:
2x = 4 * 6
2x = 24
Dividing both sides by 2, we find:
x = 12 mL
Next, we need to convert mL to teaspoons. There are 5 mL in 1 teaspoon, so:
12 mL / 5 mL/teaspoon = 2.4 teaspoons
Therefore, the patient needs to take 2.4 teaspoons of cough medication.
