Final answer:
In calculating the amount of codeine ingested, 12 teaspoons of the medication equates to 60 mL, with a corresponding codeine content of 120 mg, which is not listed among the given options.
Step-by-step explanation:
To calculate how many milligrams of codeine would have been taken after consuming 12 teaspoons of the cough suppressant, we first need to convert the amount of medication taken from teaspoons to milliliters. Then we can determine the amount of codeine in milligrams.
There are approximately 5 milliliters in 1 teaspoon. The medication contains 10 mg of codeine per 5 mL. If the individual took 12 teaspoons, the total volume taken is:
12 tsp × 5 mL/tsp = 60 mL
Since there are 10 mg of codeine in every 5 mL of the medication, the total amount of codeine ingested is:
60 mL ÷ (5 mL/10 mg) = 120 mg
Therefore, the correct answer is not listed among the options provided.
