Answer 1

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.
