Final answer:
Hoarseness, stridor, accessory respiratory muscle use, sternal retraction are signs of B. Laryngeal injury
Step-by-step explanation:
Hoarseness, stridor, accessory respiratory muscle use, and sternal retraction are signs typically associated with laryngeal injury. Laryngeal injury refers to damage or trauma to the larynx, which is the organ housing the vocal cords. These signs may indicate a range of conditions affecting the larynx, such as vocal cord dysfunction, laryngitis, or physical injury to the laryngeal structures.
Hoarseness is a common symptom of laryngeal injury, often indicating disruptions in vocal cord function. Stridor, a high-pitched sound during breathing, can result from narrowed or obstructed airways in the larynx.
Accessory respiratory muscle use and sternal retraction are indicators of increased effort in breathing, suggesting that the airway may be compromised, leading to the recruitment of additional muscles to support respiration.
In summary, B. the signs of hoarseness, stridor, accessory respiratory muscle use, and sternal retraction collectively point to laryngeal injury. Recognizing these clinical manifestations is crucial for healthcare professionals in diagnosing and addressing conditions affecting the larynx, which can have significant implications for both respiratory function and vocal cord health.
