A client is taking nebulizer treatments for asthma, and the nurse is instructing the client in the correct method for measuring peak expiratory flow rates (PEFR) after treatment. The nurse prepares the meter with the indicator at the base of the scale. Place the following steps (Roman numerals) in the correct order from first to last.
Correct Answer: A,D,B,C
Rationale: Measuring peak expiratory flow rates (PEFR) requires a specific sequence to ensure accurate results. First, having the client sit upright or stand (A) promotes optimal lung function and airflow. Next, the client takes a deep breath (D) to fill the lungs completely, which is essential for an accurate measurement. After inhalation, the client places the meter in their mouth and seals their lips (B) to prevent air leakage, ensuring the reading reflects true airflow. Finally, the client expels air forcefully through the meter (C), providing the peak flow measurement. Each step is crucial for obtaining reliable data; skipping any can compromise the accuracy of the results.
