A nurse is teaching a client about using a peak flow meter for asthma management. What does a decrease in peak flow measurements indicate to the client?
"It means your asthma is under control, and you can reduce your medications."
"You should start using your rescue inhaler more frequently."
"Your asthma may be worsening, and you should follow your asthma action plan."
"Peak flow measurements are not related to asthma management."
The Correct Answer is C
A) Incorrect. A decrease in peak flow measurements typically indicates worsening asthma, not improved control.
B) Incorrect. While an increase in rescue inhaler use may be necessary during an exacerbation, it does not address the underlying issue of worsening asthma.
C) Correct. A decrease in peak flow measurements is a sign of declining lung function, suggesting that asthma may be worsening. Following the asthma action plan is essential in this situation.
D) Incorrect. Peak flow measurements are a valuable tool in asthma management and are related to monitoring and controlling asthma symptoms.
