A client is concerned about contracting tuberculosis (TB) while traveling to countries with a high TB burden. What advice should the nurse provide regarding prevention?
"You can prevent TB by avoiding close contact with anyone in the high-burden area."
"Wearing a surgical mask at all times will protect you from TB transmission."
"Getting vaccinated with the BCG vaccine is the most effective way to prevent TB."
"Follow good respiratory hygiene and avoid overcrowded, poorly ventilated places."
The Correct Answer is D
A) Incorrect. Avoiding close contact alone may not be sufficient, as TB is primarily transmitted through the inhalation of respiratory droplets.
B) Incorrect. While wearing a surgical mask may offer some protection, it is not foolproof, especially in high-burden areas.
C) Incorrect. The BCG vaccine provides some protection against severe forms of TB in children but is not considered highly effective for preventing TB in adults.
D) Correct. Following good respiratory hygiene and avoiding crowded, poorly ventilated areas are essential measures to reduce the risk of TB transmission in high-burden areas.

B) Correct. Chest X-rays are valuable in assessing the extent of lung involvement, the presence of cavities, and other abnormalities related to TB. This information helps guide treatment decisions.
C) Incorrect. Chest X-rays are not primarily used to detect TB infection in the blood; they focus on lung and chest abnormalities.
D) Incorrect. Chest X-rays are routinely used in the diagnosis and management of TB, especially for assessing lung involvement.
Correct Answer is A
Explanation
A) Correct. Using multiple drugs to treat TB reduces the risk of drug resistance development, as it targets the bacteria from different angles and makes it harder for them to become resistant to one or more drugs.
B) Incorrect. While using multiple drugs may help manage side effects by spreading the burden of treatment, the primary purpose is to prevent drug resistance.
C) Incorrect. Shortening the treatment duration is a goal, but it is not the primary purpose of using multiple drugs.
D) Incorrect. Although improving patient compliance is important, the primary purpose of using multiple drugs is to reduce drug resistance.
