The recommended action when obtaining a peak expiratory flow rate from an adolescent involves ensuring that the client is in a position that facilitates optimal lung expansion and airflow. Having the client stand during the procedure is ideal because it allows for better diaphragmatic movement and enhances the accuracy of the measurement. Standing eliminates any potential restriction that might occur if the individual were seated, thereby providing a more reliable flow rate reading.

While the other considerations—such as documenting the average of the attempts and instructing on the correct technique—are important aspects of the overall process, the physical position of the client plays a crucial role in obtaining an accurate measurement. It’s essential to have the client perform the task correctly for reliable results, but the foundational step of being upright should not be overlooked as it directly impacts the respiratory mechanics involved in the procedure.
