A nurse is providing teaching to a client who has osteoarthritis and reports taking a glucosamine supplement daily. Which of the following statements should the nurse make?

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.

A) Muscle twitching:
Muscle twitching, also known as tetany, is a common manifestation of hypocalcemia. Low calcium levels increase neuromuscular excitability, leading to symptoms such as muscle cramps, spasms, and twitching. This is a key clinical sign that helps in diagnosing hypocalcemia.
B) Bounding pulse:
A bounding pulse is not typically associated with hypocalcemia. Instead, it is more often seen in conditions such as fluid overload or hyperdynamic circulatory states, where there is increased cardiac output or vascular volume.
C) Hypertension:
Hypertension is not a common manifestation of hypocalcemia. Hypocalcemia is more likely to cause hypotension due to its effect on cardiac contractility and vascular tone, rather than causing high blood pressure.
D) Decreased bowel sounds:
Decreased bowel sounds are not commonly associated with hypocalcemia. Hypocalcemia affects neuromuscular function, but it typically causes increased gastrointestinal motility rather than decreased motility, which would lead to hyperactive bowel sounds rather than decreased ones.
