The public health nurse is investigating a botulism outbreak. The public health nurse understands that which of the following is the greatest risk factor for development of the disease?
A recent potluck that had a petting zoo
A recent potluck that served spinach
A recent potluck that served baked beans out of a bent can
A recent potluck that served pork products
The Correct Answer is C
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.

Correct Answer is B
Explanation
A. Dengue: Dengue is transmitted by Aedes mosquitoes and is found in tropical regions, but it is less commonly imported to the U.S. than malaria.
B. Malaria: Malaria is the most frequently imported vector-borne disease in the U.S. due to international travelers coming from endemic areas (Africa, South Asia, South America). It is transmitted by Anopheles mosquitoes.
C. Onchocerciasis (river blindness): This disease is primarily found in Africa and is not commonly imported to the U.S. by travelers.
D. Yellow fever: While yellow fever exists in endemic areas, travelers are often vaccinated before visiting these regions, reducing its importation risk.
Correct Answer is B
Explanation
A. Abstinence is the only way to be certain you are HIV free: While abstinence eliminates the risk, it is not the only preventive measure. Safer sex practices, such as condom use and PrEP (pre-exposure prophylaxis), can significantly reduce the risk of HIV.
B. The test would not cover any recent infection, so if the client has had recent unprotected sex, the test should be repeated in 3 months. HIV has a "window period" during which recent infections may not yet be detectable. Retesting in 3 months ensures accuracy and proper diagnosis.
C. The test could be wrong and the client might still have an HIV infection: Modern HIV tests are highly accurate, but recent infections may not be detected. Instead of causing unnecessary distress, the focus should be on retesting after the window period.
D. Sex should be restricted to one partner: Monogamy does not guarantee HIV prevention unless both partners are tested and remain faithful. The emphasis should be on safe sex practices.
