Final answer:
The question relates to a health procedure where a client must create a tight seal with a mouthpiece for accurate measurement or delivery of respiratory therapy. Clarity in instructions and demonstration help in proper use.
Step-by-step explanation:
The instruction 'Instruct the client to place tightly around the mouth piece' typically pertains to medical or health procedures involving respiratory assessments or treatments where clients may use devices such as a spirometer or an inhaler. A tight seal is necessary to ensure that the device measures or delivers the therapy effectively. This may involve the use of a mouthpiece or a mask. When instructing a client, it's important to be clear and demonstrate the procedure if possible. Explain that they need to wrap their lips around the mouthpiece firmly to prevent air from escaping, ensuring that the breath goes into or is measured by the device accurately.
