Step-by-step explanation:
To assist the client in providing a sputum sample, the PN (Practical Nurse) can help by explaining the process and providing instructions to the client. The PN can ask the client to take a deep breath and then cough forcefully to produce sputum. The sputum should be collected in a sterile container provided by the PN. It is important for the client to avoid contaminating the sample with saliva or mucus from the nose. The client should also be instructed to avoid eating or drinking anything for at least 1 hour before providing the sample to ensure that the sputum is not mixed with food particles.
