Which category includes Anti-infectives, Flu vaccine, Pneumonia vaccine, and Antivirals?

• A. Endocrine system medications
• B. Digestive system medications
• C. Immune/Lymphatic system medications
• D. Reproductive System medications

Answer: (C)

This question is about grouping drugs by the body system they primarily affect. Anti-infectives, vaccines, and antivirals all revolve around defending the body against infections, which is handled by the immune/lymphatic system. Anti-infectives kill or inhibit invading pathogens (bacteria, fungi, viruses) to prevent or treat infections. Vaccines work by training the immune system to recognize specific germs, building protection before illness occurs. Antivirals specifically target viral replication to control viral infections. Because these medications work with the immune defense and infection control, they fit the immune/lymphatic system category.

Endocrine system medications relate to hormones and metabolic regulation, digestive system medications affect the GI tract, and reproductive system medications target reproductive organs and processes.
