Which of the following is a common airway-related risk for obese patients during anesthesia induction?

Obesity makes airway management during anesthesia induction more challenging because anatomy and physiology shift in ways that hinder securing the airway. Extra tissue in the tongue and pharynx, a relatively short, thick neck, limited neck extension, and reduced jaw mobility can all narrow the upper airway and blunt the view during laryngoscopy. This raises the likelihood that a standard direct laryngoscope will fail to provide a clear view of the vocal cords, making intubation difficult or prolonged. Because time without a secured airway is dangerous—obese patients desaturate more quickly due to reduced functional residual capacity and higher oxygen demand—this airway difficulty is a critical concern during induction. That combination of difficult visualization and rapid desaturation makes difficult intubation the most pertinent airway-related risk in this setting. Aspiration is indeed a concern in obese patients, since a full stomach and gastroesophageal reflux can increase the risk during induction, but the question focuses on the immediate airway management challenge encountered when securing the airway. Atelectasis is common and contributes to postoperative ventilation issues, and DVT/PE are thromboembolic risks, not airway-related events during the induction sequence.
