In a patient with tachycardia and wheezing, what treatment should the nurse anticipate?

In a patient presenting with tachycardia and wheezing, the symptoms strongly suggest an underlying bronchospasm, which is common in conditions such as asthma or chronic obstructive pulmonary disease (COPD). Bronchodilators are the primary treatment for acute bronchospasm as they work by relaxing the muscles of the airways, leading to dilation and improved airflow. This is critical in alleviating wheezing and enhancing the patient's breathing.

While other treatments might be relevant in specific contexts—such as antibiotics for infections, steroids for reducing inflammation, and oxygen therapy for improving hypoxia—bronchodilators specifically target the immediate problem of airway constriction. In this acute situation, addressing the bronchospasm is essential, making bronchodilators the most appropriate initial treatment to manage the patient's symptoms effectively.
