Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. The portal of exit is where the infectious agent leaves the reservoir host. 2. Covering the mouth when sneezing helps prevent the spread of respiratory infections through droplets. 3. By covering the mouth, the risk of releasing infectious droplets into the environment decreases, thus reducing transmission. 4. This practice is a direct way to prevent the exit of infectious agents from the reservoir host. Summary of why other choices are incorrect: - B: Keeping surfaces clean and dry is related to the mode of transmission or reservoir, not specifically to the portal of exit. - C: Getting a vaccine for a particular disease is a preventive measure but not directly related to the portal of exit. - D: Handwashing is important for infection prevention but is more related to breaking the chain at the mode of transmission stage, not at the portal of exit.

Serving drinks while standing (B) does not directly address the issue of water temperature. Leaving warm water applications on for 30 minutes (C) is not recommended as it can also lead to burns. It is crucial to always check water temperature to prevent burns and scalds.
