A nurse is providing postoperative teaching to a client who had a coronary artery bypass graft due to arteriosclerosis. Which of the information should the nurse include in the teaching regarding exercise?

A) Asking the client how she feels about her understanding of diabetes can provide some insight into her confidence and perceived knowledge. However, it does not objectively measure her actual understanding or ability to apply diabetes management information.

B) Asking the client how often she reads food labels assesses a specific behavior related to diabetes management but does not fully evaluate the client's overall health literacy. The frequency of reading food labels may indicate some level of engagement, but it does not necessarily reflect comprehensive understanding or effective diabetes self-management.

C) Requesting the client to explain what she read from a brief handout about diabetes management provides a direct assessment of her comprehension and retention of diabetes management information. This approach effectively measures her ability to understand and apply critical health information, which is a core component of health literacy.

D) Inquiring about the timing of her last HbA1c test assesses adherence to diabetes monitoring but does not gauge the client's understanding of diabetes management. While important, this question does not provide a clear picture of her health literacy or ability to manage her condition effectively.

A) Double-bag the client's trash before removing it from the room: While double-bagging is a precaution used in certain infections to prevent contamination, it is not necessary for influenza. Influenza spreads via respiratory droplets rather than contact with contaminated objects. Standard waste disposal methods are typically sufficient to manage the risk of contamination from trash.

B) Place the client in a negative air pressure room with 6 to 12 air exchanges per hour: Negative air pressure rooms are designed to contain airborne pathogens by preventing contaminated air from escaping the room. Diseases such as tuberculosis or measles require this level of isolation. However, influenza spreads through droplets that settle quickly rather than remaining airborne, making negative air pressure rooms unnecessary for influenza isolation.

C) Ensure all air in the client's room is filtered through a HEPA filter: HEPA (High-Efficiency Particulate Air) filters are used to trap airborne particles. For influenza, which is spread by larger respiratory droplets, such filtration is not needed. The droplets are too large to remain suspended in the air and are typically spread through close contact, rather than requiring air filtration.

D) Wear a surgical mask when within 1 m (3 ft) of the client: This is the most appropriate precaution. Influenza is primarily spread through respiratory droplets that can travel about 1 meter (3 feet) when a person coughs, sneezes, or talks. Wearing a surgical mask within this distance helps prevent inhaling these droplets, thus reducing the risk of transmission. This aligns with droplet precautions which are standard for managing influenza.
