A nurse is reinforcing teaching about promoting rest and sleep with a client who reports insomnia. Which of the following statements should the nurse identify as an indication that the client understands the teaching?

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: Cleaning the incision with soap and water is not typically recommended as it can disrupt the healing process and may lead to irritation or infection. The incision should be kept clean and dry, and any cleaning should be done according to the surgeon's instructions.

Choice B reason: Performing hand hygiene before dressing changes is essential in preventing incisional infections. Hand hygiene is one of the most effective ways to prevent the spread of infections, including those at surgical sites.

Choice C reason: Protective isolation is used for immunocompromised patients to protect them from infections, not typically for postoperative patients unless they are at high risk for infection due to other conditions.

Choice D reason: Allowing the wound to air can be part of the healing process, but it must be done carefully and under the guidance of healthcare professionals to ensure that the wound is protected from contamination.
