Which of the following is a common sign of respiratory distress?

Shortness of breath, or dyspnea, is widely recognized as a common sign of respiratory distress. When the body struggles to obtain sufficient oxygen or eliminate carbon dioxide, individuals may experience increased difficulty in breathing. This sensation can manifest as rapid or labored breathing, and a person might also exhibit signs such as using accessory muscles to breathe, nasal flaring, or an overall appearance of anxiety or panic due to the sensation of not being able to breathe effectively.

In the context of respiratory distress, shortness of breath can arise from various conditions including asthma exacerbations, chronic obstructive pulmonary disease (COPD), pneumonia, or heart failure. These conditions affect oxygen exchange in the lungs, leading to the feeling of breathlessness that prompts individuals to seek assistance.

While other options like bradycardia, low blood pressure, and decreased body temperature can be associated with respiratory issues, they do not specifically indicate respiratory distress. Bradycardia relates to a slow heart rate, which may not necessarily link to respiratory function. Low blood pressure can occur due to various factors including dehydration or shock but isn't a direct indicator of respiratory distress. Decreased body temperature typically signals hypothermia or other systemic issues, rather than a direct problem with breathing or lung function. Thus
