An 80-year-old woman comes to the community health care facility with a large bag of medications. She tells the nurse she can no longer afford these medications because her only income is Social Security. Which statement is the best response by the nurse?

A. Hepatitis B: Hepatitis B is a bloodborne disease, primarily spread through contact with infected bodily fluids, not through a vector.

B. Rocky Mountain spotted fever: Rocky Mountain spotted fever is a vector-borne disease transmitted by tick bites. Vectors are living organisms, such as mosquitoes or ticks, that carry infectious agents.

C. E. coli O157:H7: E. coli is a foodborne illness that spreads through contaminated food or water, not via a vector.

D. Anthrax: Anthrax is a bacterial infection that spreads through direct contact, ingestion, or inhalation of spores, not through a vector.

A. A recent potluck that had a petting zoo: While petting zoos can be sources of zoonotic infections like E. coli or Salmonella, they are not associated with botulism, which comes from improperly processed foods.

B. A recent potluck that served spinach: Spinach can harbor bacterial infections like E. coli or Listeria, but it is not a common source of botulism unless improperly canned.

C. A recent potluck that served baked beans out of a bent can: Botulism is caused by Clostridium botulinum, a bacterium that produces neurotoxins in improperly canned, preserved, or stored foods. A bent or bulging can suggests contamination and potential toxin production, making it the most likely cause of botulism in this scenario.

D. A recent potluck that served pork products: Pork can transmit trichinosis (from undercooked meat) or bacterial infections (Salmonella, Listeria), but botulism is primarily linked to canned foods, not pork products.
