Final answer:
The maximal O₂ flow rate for a client with COPD is typically between 1-2 L/min. It is important to consult with a healthcare professional for the appropriate flow rate.
Step-by-step explanation:
The maximal O₂ flow rate for a client with COPD is typically between 1-2 L/min. This is because high flow rates can cause discomfort and can lead to oxygen toxicity in patients with COPD. Additionally, providing higher flow rates does not necessarily increase the amount of oxygen reaching the patient's tissues.
It is important to note that the specific maximal O₂ flow rate may vary based on the individual patient's condition and needs. It is always best to consult with a healthcare professional to determine the appropriate flow rate for a client with COPD.
