Question: 1 / 400

What is TRUE regarding work of breathing?

Palpation of the accessory muscles can identify increased work of breathing.

Intercostal retractions and nasal flaring may indicate increased work of breathing.

Increased work of breathing often presents with observable physical signs that indicate the body is struggling to ventilate adequately. Intercostal retractions, which occur when the muscles between the ribs pull inward during inhalation, signify that more effort is being exerted to expand the thoracic cavity and draw air into the lungs. Nasal flaring, an action commonly seen in children, shows that they are attempting to increase airflow during periods of respiratory distress. Both these signs are indicative of respiratory distress and point toward the body's increased effort in breathing.

Understanding these manifestations is critical in assessing patients who may be struggling with respiratory conditions, where the work of breathing can be significantly compromised. Recognizing these early signs can prompt timely intervention and management, making this knowledge essential for effective nursing practice in critical care and transport situations.
