A nurse is providing teaching to a client who has type 1 diabetes mellitus and her partner about how to manage severe hypoglycemia at home. Which of the following actions should the nurse instruct the partner to perform first?

A) Potatoes: Potatoes are not particularly high in oxalates and can be included in the diet for individuals who have had calcium oxalate renal calculi. They do not significantly contribute to oxalate levels and are generally considered safe for those managing this type of kidney stone.

B) Mushrooms: While mushrooms are a nutritious food, they do not have a high oxalate content compared to other foods. Therefore, they are not a primary concern for individuals managing calcium oxalate stones.

C) Eggs: Eggs are low in oxalates and do not contribute significantly to the formation of calcium oxalate renal stones. They are a good source of protein and can be included in the diet.

D) Spinach: Spinach is high in oxalates and should be limited in the diet of individuals who have experienced calcium oxalate renal calculi. High oxalate foods can contribute to the formation of calcium oxalate stones, so limiting spinach can help reduce the risk of recurrence.

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.
