A nurse is teaching a newly licensed nurse about reducing the risk of needlestick injuries. Which of the following instructions should the nurse include?

A. This statement suggests that outcomes are unpredictable and not influenced by factors such as adherence to a medical regimen or behavioral changes. According to the Theory of Reasoned Action/Planned Behavior, behavior is influenced by attitudes and intentions, which can be assessed and potentially modified through education and intervention.
B. Poor adherence to the recommended medical regimen (such as diet, exercise, and possibly medication) increases the risk of complications in individuals with diabetes mellitus. According to the Theory of Reasoned Action/Planned Behavior, if the client has negative attitudes toward the meal plan and exercise regimen (low motivation), and if they perceive these behaviors as difficult to perform (low perceived behavioral control), they are less likely to adhere to the plan. This could lead to poor outcomes, including complications related to diabetes.
C. This option suggests that outcomes will not significantly differ regardless of the client's adherence to the medical regimen or behavioral changes. However, according to the Theory of Reasoned Action/Planned Behavior, attitudes, subjective norms, and perceived behavioral control influence behavior and subsequently affect outcomes.
D. Education plays a critical role in the Theory of Reasoned Action/Planned Behavior. By providing education, the nurse can influence the client's attitudes and perceptions regarding the importance and feasibility of adhering to the meal plan and starting an exercise regimen.

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).
