Isolation in a negative-pressure room

Frequent handwashing with soap and water

Wearing a surgical mask at all times

Avoiding close contact with the client

Answer and Explanation

The Correct Answer is A

A) Correct. Isolation in a negative-pressure room is the standard precaution for preventing the transmission of TB in healthcare settings, as it helps contain airborne pathogens.

B) Incorrect. While handwashing is important for general infection control, it is not the primary measure for preventing TB transmission.

C) Incorrect. Wearing a surgical mask at all times is not sufficient to prevent TB transmission, especially in a healthcare setting.

D) Incorrect. Avoiding close contact with the client is not a practical measure for healthcare professionals providing care to TB patients. Proper isolation measures are more effective.

Correct Answer is C

Explanation

A) Incorrect. Completing treatment does not guarantee that the client will not develop TB again in the future, but it reduces the risk of a relapse.

B) Incorrect. Stopping treatment early does not reduce the risk of side effects; it increases the risk of drug resistance and a relapse.

C) Correct. Completing the full course of treatment is essential to prevent the development of drug-resistant TB and ensure effective treatment.

D) Incorrect. TB treatment should be completed as prescribed, regardless of the absence of symptoms, to prevent drug resistance and relapse.

A. "TB bacteria are dormant and do not replicate in the body during latent infection." B. "The immune system immediately eliminates TB bacteria during the latent phase." C. "Latent TB infection occurs in the lungs, where it does not cause symptoms." D. "TB bacteria actively multiply in the body but at a very slow rate during latency."

Correct Answer is A

Explanation

A) Correct. During latent TB infection, TB bacteria are in a dormant state and do not actively replicate or cause symptoms. They can become active and multiply if the immune system weakens.

B) Incorrect. While the immune system can control TB bacteria during latency, it does not immediately eliminate them.

C) Incorrect. Latent TB infection can occur in various parts of the body, not just the lungs, and it typically does not cause symptoms.

D) Incorrect. TB bacteria in latent infection are in a dormant state and do not actively multiply, although they remain viable.
