Final answer:
The incorrect statement is (A), which mistakenly suggests using cromolyn for immediate relief of tight breathing. Cromolyn is for long-term control, whereas albuterol is the appropriate medication for fast relief during an asthma attack.
Step-by-step explanation:
The client's statement that indicates a need for further teaching is (A) "If my breathing begins to feel tight, I will use the cromolyn immediately." Cromolyn is a medication used for the long-term control and prevention of asthma symptoms, not for immediate relief of acute symptoms. In the event of breathing difficulties or an asthma attack, a fast-acting bronchodilator like albuterol should be used. Albuterol works quickly to relax the muscles around the airways and improve breathing. It is also often recommended to be taken before exercise to prevent exercise-induced bronchoconstriction. Cromolyn, on the other hand, should be taken regularly as prescribed to maintain control over asthma and is not designed for quick relief of symptoms. Furthermore, if both medications are prescribed for use, it is generally advised that they be taken several minutes apart, as indicated by the client's correct understanding in statement (D).
