A nurse is explaining the process of collecting sputum samples for tuberculosis (TB) testing to a client. Which instruction should the nurse provide to ensure an accurate sample?
"Collect sputum samples immediately after waking up in the morning."
"Rinse your mouth with water before collecting the sputum to ensure cleanliness."
"Avoid deep coughing when producing sputum samples."
"Collect sputum samples in any container you have available."
The Correct Answer is A

B) Incorrect. Rinsing the mouth before collecting sputum may dilute the sample and reduce its accuracy.
C) Incorrect. Deep coughing is encouraged to obtain samples from the lower respiratory tract, where TB bacteria are more likely to be present.
