A nurse is monitoring a postoperative client who is unable to respond to questions. Which of the following nonverbal behaviors should the nurse identify as an indication that the client is experiencing pain? (Select all that apply)

Choice A reason: Placing a client with active pulmonary TB in a room with positive airflow is not recommended, as positive airflow would push potentially contaminated air into general circulation, risking the spread of TB. Instead, a room with negative airflow is appropriate to contain and remove contaminated air.

Choice B reason: Determining whether the client lives alone or with others is important for public health and contact tracing purposes. If the client lives with others, those individuals may need to be tested and monitored for TB as well.

Choice C reason: Using an alcohol-based hand cleaner is a standard practice unless hands are visibly soiled. If hands are visibly soiled, handwashing with soap and water is necessary.

Choice D reason: Reminding the client to cover their mouth with a tissue when coughing is a key measure to prevent the spread of TB, which is transmitted through airborne particles from coughs or sneezes.

Choice E reason: Antifungal medications are not used to treat TB, which is caused by a bacterium, not a fungus. The client should be instructed about taking anti-tuberculosis medications, not antifungals.

Choice A reason: Urinary catheterization is a well-known risk factor for HAIs, particularly catheter-associated urinary tract infections (CAUTIs). The use of indwelling urinary catheters can introduce bacteria into the urinary tract and is associated with a significant proportion of HAIs.

Choice B reason: While malnutrition can affect the immune system and increase the risk of infections, it is not a direct cause of HAIs. Good nutritional status is important for wound healing and infection prevention, but it does not cause HAIs by itself.

Choice C reason: Having multiple caregivers can increase the risk of transmitting infections, especially if hand hygiene and other infection control practices are not consistently followed. However, it is not considered a direct cause of HAIs like urinary catheterization is.

Choice D reason: Chlorhexidine washes are actually used as a preventive measure against HAIs, particularly in reducing the risk of surgical site infections. They are not a cause of HAIs but rather part of the solution to prevent them.
