A client with asthma asks a nurse how to properly use a peak flow meter. What should the nurse instruct the client to do?
"Breathe as deeply as possible into the peak flow meter to get an accurate reading."
"Stand up straight and exhale forcefully into the peak flow meter."
"Place the peak flow meter in your mouth and inhale deeply."
"Stand with your feet together and blow into the peak flow meter gently."
The Correct Answer is D
A) Incorrect. Breathing too forcefully into the peak flow meter can result in artificially high readings. The client should use a steady, controlled breath.
B) Incorrect. Exhaling forcefully can also lead to inaccurate readings. Gentle exhalation is recommended.
C) Incorrect. The peak flow meter should be exhaled into, not inhaled from.
D) Correct. The correct technique involves standing with feet together and exhaling gently but forcefully into the peak flow meter.
