A nurse is ordered to collect a sputum specimen from a client. The nurse instructs the client to cough up the sputum to obtain the most accurate result. What is the rationale for such an instruction?
A) Prevents contamination of the specimen
B) Prevents the proliferation of microorganisms
C) Brings up sputum specimen from the lungs
D) Reduces risk of transmission of infection
C
Feedback:
Coughing up the sputum brings up the specimen from the lungs and the bronchi so that the sample collected is sputum and not merely mucus. Coughing directly into the container and covering the container immediately after collection of sputum prevents contamination of the specimen. Transporting the collected specimen immediately to the laboratory prevents the proliferation of microorganisms. Proper glove disposal and handwashing following the specimen collection reduce the risk of transmission of infection.
