-

-
"Over time, my body may not respond to this medication as well."
-
"This medication can help prevent asthma symptoms when I exercise."
-
✓
"I'll take this medication when I start having sudden shortness of breath."
Answer & explanation
Correct: "I'll take this medication when I start having sudden shortness of breath."
LABAs (e.g., salmeterol, formoterol) have a slow onset of action and are used for prevention and long-term control, NOT for acute symptoms or sudden shortness of breath. Short-acting beta agonists (SABAs) such as albuterol are used as rescue inhalers. Tachycardia is a known side effect of beta agonists. Tolerance with prolonged use is possible. LABAs are appropriate for prevention before exercise (in combination therapy). Using a LABA as a rescue is dangerous and requires further teaching. Reference: GINA Guidelines.
