Final answer:
Asthma is characterized by symptoms including dyspnea, retractions, anxiety, and wheezing. Bradycardia is not a typical symptom of asthma; a rapid pulse is more common during severe attacks.
Step-by-step explanation:
The clinical manifestations that occur with asthma include dyspnea (shortness of breath), retractions (visible sinking of the chest wall during breathing effort), anxiety, and wheezing. Bradycardia is not typically associated with asthma; in fact, a rapid pulse is more commonly seen during an asthma attack, especially if it is severe. Asthma can be characterized by difficulty breathing, coughing, tightness of the chest, and excessive mucus production. Symptoms can be triggered by various factors, including allergens, exercise, stress, and respiratory infections.
