Which of the following adverse effects may occur with respiratory tract drugs?

• A. Diarrhea
• B. Tachycardia
• C. Increased appetite
• D. Ear pain

Answer: (B)

Tachycardia is a well-documented adverse effect associated with several respiratory tract medications, especially those that are bronchodilators. These drugs often act by stimulating beta-adrenergic receptors to relax the smooth muscle in the airways, which can inadvertently increase heart rate. This is particularly common with certain types of inhalers or nebulized solutions that contain albuterol or similar beta-agonists. Understanding this effect is important for healthcare providers when they are assessing a patient’s response to respiratory therapies, as it allows for better monitoring and management of potential cardiovascular implications. In contrast, while other side effects like diarrhea, increased appetite, and ear pain can occur with various medications, they are not typically associated with respiratory drugs specifically and their mechanisms of action.
