A nurse is providing teaching to a client who has a new diagnosis of type 2 diabetes mellitus. The nurse should recognize that the client understands the teaching when he identifies which of the following as manifestations of hypoglycemia? (Select all that apply.)

A. An N-95 respirator is designed to filter out airborne particles and is used primarily for protection against airborne diseases such as tuberculosis or certain respiratory infections like COVID-19. It is not necessary for contact precautions unless there is also a risk of airborne transmission.

B. Goggles protect the eyes from splashes, sprays, or droplets of infectious material. They are not typically required for routine contact precautions unless there is a risk of splashes or sprays to the eyes.
C. Gloves are essential for contact precautions. They protect the nurse's hands from direct contact with potentially infectious material on the client's bed linen or any contaminated surfaces. Gloves should be worn when handling soiled linen and removed and discarded appropriately after use.
D. A face shield provides full-face protection against splashes, sprays, or splatters of infectious material. It is particularly useful when there is a risk of exposure to bodily fluids or during procedures that may generate splashes. While not always required for routine contact precautions, it may be used depending on the specific situation, such as when cleaning surfaces heavily contaminated with body fluids.

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).
