A nurse is providing education to a client with active tuberculosis (TB) about the duration of treatment. The client asks how long they will need to take medications. What is the nurse's best response?

A) Correct. LTBI is not contagious, as the bacteria are dormant and not actively causing illness. Active TB disease, on the other hand, is contagious and can be transmitted to others through respiratory droplets.

B) Incorrect. LTBI is not contagious, whereas active TB disease is contagious.

C) Incorrect. LTBI and active TB disease have different symptoms and treatment approaches. LTBI has no symptoms, while active TB disease presents with symptoms and requires treatment to prevent progression.

D) Incorrect. LTBI does not always progress to active TB disease. In fact, many individuals with LTBI do not develop active disease, but they are at risk, especially if their immune system becomes compromised.

A) Incorrect. While it is essential to minimize close contact, isolation from family members is not typically necessary. Effective treatment and infection control measures can reduce the risk of transmission.

B) Incorrect. Wearing a mask at all times at home may not be necessary, but it is important to follow respiratory hygiene practices, especially when close to others.

C) Correct. Good hand hygiene and proper respiratory etiquette, such as covering the mouth when coughing, can help reduce the risk of TB transmission within the household.

D) Incorrect. TB can be transmitted in close household settings, so infection control measures are important to prevent transmission to family members.
