What is the maximum amount of pseudoephedrine that can be sold to a patient in one day according to federal law?

The correct answer is based on federal regulations surrounding the sale of pseudoephedrine, which is a precursor to methamphetamine. According to the Combat Methamphetamine Epidemic Act of 2005, which regulates the sale of products containing pseudoephedrine, a retail distributor can sell no more than 3.6 grams of pseudoephedrine per day to an individual purchaser.

This 3.6-gram limit is designed to control the quantity that could potentially be purchased for illicit drug manufacturing while still allowing legitimate use for treating conditions such as sinus congestion and allergies. The law further stipulates that this quantity applies to the sale of pseudoephedrine in a single day to ensure that individuals do not circumvent the limit by making multiple purchases on the same day.

Other choices exceed this daily limit, thereby not reflecting the legal restrictions imposed on the sale of pseudoephedrine under federal law. Understanding this specific limit is essential for compliance with federal regulations regarding controlled substances.
