Which option best describes two reasons critically ill children have an increased risk of aspiration?

• A. Decreased strength and coordination of pharyngeal muscles and weak cough reflex
• B. Increased gastric residuals and deep sedation
• C. Strong cough reflex and rapid gastric emptying
• D. Normal swallowing and gag reflex

Answer: (A)

Two main factors raise aspiration risk in critically ill children: diminished strength and coordination of the pharyngeal muscles, and a weak cough reflex. When the pharyngeal muscles are weak or poorly coordinated, swallowing can fail to protect the airway, allowing food or secretions to slip into the larynx and trachea. A weak cough reflex then reduces the body’s ability to clear any material that has entered the airway, increasing the chance that it will be aspirated deeper into the lungs. Other options describe factors that are not as directly tied to swallowing safety or would, in fact, reduce risk (like normal swallowing and a robust gag reflex). While deep sedation can contribute to aspiration risk, increased gastric residuals alone represent feeding intolerance rather than a direct two-part mechanism of impaired swallow and airway protection.
