A nurse is educating a client about the risk factors for tuberculosis (TB). Which statement made by the client indicates a correct understanding of the risk factors for TB?
"TB is primarily transmitted through contaminated water and food sources."
"Having a family history of TB does not increase my risk of contracting the disease."
"Living in crowded and poorly ventilated environments can increase my risk of TB."
"TB is not influenced by underlying health conditions like HIV or diabetes."
The Correct Answer is C
A) Incorrect. TB is primarily transmitted through the inhalation of respiratory droplets from an infected person and is not related to contaminated water or food sources.
B) Incorrect. Having a family history of TB can increase the risk, as there may be genetic factors that affect susceptibility to the disease.
C) Correct. Crowded and poorly ventilated settings increase the risk of TB transmission, as the bacteria can be easily spread in close quarters.
D) Incorrect. Underlying health conditions like HIV, diabetes, and immunosuppression can indeed increase the risk of TB due to compromised immune function.
