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.
