Which of the following is a known risk factor for aspiration in critically ill patients?

• A. Neuromuscular disease
• B. Hypoglycemia
• C. Normal level of consciousness
• D. Small amount of formula

Answer: (A)

Impaired airway protection from swallowing due to neuromuscular disease increases aspiration risk in critically ill patients. When the muscles that coordinate swallowing and protect the airway are weak or discoordinated, material from the oropharynx or stomach can more easily enter the trachea, especially during feeding or reflux. In the critically ill, this risk is amplified by factors such as sedation, intubation, and a blunted cough or gag reflex, but the underlying neuromuscular dysfunction directly elevates the chance of aspiration. Hypoglycemia does not inherently affect swallowing or airway protection; a normal level of consciousness suggests intact protective reflexes, which lowers aspiration risk; a small amount of formula by itself isn’t a recognized risk factor as strongly as impaired swallowing mechanics.
