Final answer:
The client had been ingesting 6000 mg of acetaminophen per day.
Step-by-step explanation:
To calculate the amount of acetaminophen ingested per day, we need to determine the total amount of acetaminophen in two Vicodin tablets. Each tablet contains 500 mg of acetaminophen, so two tablets contain a total of 1000 mg of acetaminophen. Since the client takes two tablets every 4 hours, we can calculate the number of tablets ingested per day by dividing 24 hours (a full day) by 4 hours. This results in 6 sets of 2 tablets ingested, which equals 12 tablets.
To calculate the total amount of acetaminophen ingested per day, we multiply the amount of acetaminophen in each tablet (500 mg) by the number of tablets ingested per day (12 tablets). Therefore, the client had been ingesting 6000 mg of acetaminophen per day.
