An infection control nurse is teaching a class about transmission of infectious agents. The nurse should include that which of the following diseases is transmitted via airborne transmission?

A. An occurrence report, also known as an incident report, documents the details of any unexpected event that occurs during the client's care. This includes falls. It is important to document the incident accurately and promptly in the client's medical record to ensure that all relevant information is recorded. However, this should not take priority over timely escalation of the issue.
B. It is essential to notify the client's healthcare provider (such as the physician or nurse practitioner) about the fall incident. The provider needs to be informed about the client's condition after the fall, any injuries sustained, and any immediate actions taken.
C. The nurse who witnessed or discovered the fall incident is responsible for completing the occurrence report. It should be filled out by the nurse who directly assessed the client's condition after the fall, documented any injuries, and initiated appropriate interventions. Asking another nurse to complete the report may not accurately reflect the details and actions taken by the nurse who was directly involved.
D. Risk management may need to be informed about the fall incident, especially if it resulted in injury to the client. Risk management is responsible for assessing the circumstances surrounding the fall, identifying potential risks or contributing factors, and implementing strategies to prevent future incidents. However, contacting risk management is typically done after initial actions such as ensuring client safety, notifying the provider, and documenting the incident.

A. Communicability refers to the ability of a pathogen, such as a virus, to spread from one person to another. If a virus undergoes a mutation that increases its communicability, it means that the virus can more readily transmit from an infected person to others. This could be due to changes in viral proteins that enhance attachment to host cells, increase viral shedding, or improve survival in the environment.
B. This statement describes the concept of the infectious dose, not communicability. Infectious dose refers to the amount of virus (or pathogen) required to establish an infection in a susceptible host. A mutation that lowers the infectious dose could potentially increase the likelihood of infection, but it does not directly relate to communicability.

C. Environmental stability refers to the ability of a virus to survive outside of a host and remain capable of causing infection. While environmental stability can contribute to the overall transmission of a virus, it does not specifically define communicability, which focuses on person-to-person spread.
D. Disease severity refers to the impact of infection on the health of an individual, ranging from mild symptoms to severe illness and potential mortality. A mutation that increases disease severity does not necessarily affect communicability unless severe disease leads to behaviors that enhance transmission (e.g., increased shedding of virus).
