what must a pharmacy technician do when selling medications containing pseudoephedrine?

• check the customer’s temperature
• document the customer’s name, address, date and time of purchase, and the quantity sold
• give the customer a prescription
• require the customer to sign a waiver

Explanation:

1. An antagonist binds to a target receptor but blocks rather than triggers a biological response, preventing agonists from activating the receptor.
2. Pseudoephedrine is a regulated substance due to its potential use in illicit drug production; pharmacy technicians are required to document specific purchase details to track sales and comply with legal regulations.

Answer:

1. Binds to a receptor but doesn’t elicit a response
2. Document the customer's name, address, date and time of purchase, and the quantity sold
