- Why is the use of first-generation H1-antihistamines discouraged in clinical practice today?3. 20-year-old George Tsakino stepped on a Lego® while helping his daughter Mina pick up her toys. The Lego® broke and pierced the sole of his foot. After a visit to the emergency department at the local hospital the Lego® pieces have been removed, and there is no danger of infection. George has been bandaged, but he is limping and still in some pain. The nurse practitioner has said that he can take acetaminophen for the pain. Acetaminophen is a medication that is taken by mouth but will act at the site of the pain (in this case, in the foot). It is absorbed by the blood vessels in the small intestine. Trace the pathway taken by the acetaminophen as it travels from the site of absorption to the site of the patient's foot pain. 4.
