A nurse is providing preoperative teaching to an older adult female client who is scheduled for a laminectomy and uses supplements. Which of the following supplements should the nurse identify as increasing the client's risk for hypotension during surgery?

A. "The proxy should manage legal issues for the client." Legal matters are outside the scope of a health care proxy’s role. The proxy is authorized only to make medical decisions and does not handle legal or court-related concerns on behalf of the client.
B. "The proxy can make treatment decisions if the client is under anesthesia." The health care proxy is activated when the client is temporarily or permanently incapacitated, such as during surgery under anesthesia. At that point, the proxy can make treatment decisions aligned with the client’s values and previously expressed wishes.
C. "The proxy can make financial decisions if the need arises." Financial decisions are the responsibility of a financial power of attorney, not a health care proxy. A DPAHC limits the proxy’s authority strictly to medical and treatment-related decisions.
D. "The proxy should make health care decisions for the client regardless of the client's ability to do so." The health care proxy is not active while the client is competent and able to make decisions. The proxy only assumes responsibility when the client lacks decision-making capacity due to illness, unconsciousness, or cognitive impairment.

A. Rubeola (measles). Rubeola is transmitted through airborne particles and requires airborne precautions, including the use of an N95 respirator and placement in a negative pressure room. Droplet precautions would not provide sufficient protection due to the small particle size and long-range transmission.
B. Varicella (chickenpox). Varicella requires both airborne and contact precautions because it spreads via airborne respiratory droplets and direct contact with lesions. A client with varicella must be isolated in a negative pressure room and healthcare workers should use full PPE.
C. Tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is spread through airborne droplet nuclei, which remain suspended in the air for extended periods. It requires airborne precautions, including an N95 respirator and isolation in a specialized room.
D. Pertussis (whooping cough). Pertussis is a highly contagious bacterial infection that spreads through large respiratory droplets during coughing or sneezing. Droplet precautions are required, which include wearing a surgical mask when within 3 feet of the client and practicing proper hand hygiene to prevent transmission.
