Which of the following is a sign of asthma?

• A. Wheezing
• B. Fever
• C. Rash over body
• D. Slow heart rate

Answer: (A)

Wheezing is produced when the airways narrow due to inflammation and smooth muscle tightening in asthma, causing a high-pitched whistling sound as air moves through the constricted passages. This sound reflects the airway obstruction that characterizes an asthma flare and is a common, recognizable sign you can hear or observe during breathing difficulties. Fever points to infection rather than asthma, a rash over the body suggests a skin reaction or another condition, and a slow heart rate doesn’t fit how the body typically responds to an asthma attack (which can involve rapid breathing and a faster pulse). So, wheezing best indicates an asthma sign.
