Final answer:
It is contraindicated for a CPCT to allow a patient to cough into the air when collecting a sputum specimen; correct procedures and PPE usage are critical.
Step-by-step explanation:
When a Certified Patient Care Technician (CPCT) is collecting a patient's sputum specimen, there are several measures to ensure the process is done correctly and safely. An action that is contraindicated during this procedure is to have the patient cough directly into the air without covering their mouth, as this can spread infectious agents. Instead, the CPCT should provide the patient with a sterile container and instruct them to cough deeply from their lungs into it. The CPCT should also wear appropriate personal protective equipment (PPE), such as gloves and possibly a mask, and practice proper hand hygiene before and after the procedure to prevent the spread of infection.
