Final answer:
Sleeping with the head of the bed elevated is recommended for bariatric patients to benefit the airway and work of breathing.
Step-by-step explanation:
The position that will benefit the airway and work of breathing for a bariatric patient is sleeping with the head of the bed elevated. This position allows gravity to help control the backflow of acids from the stomach into the esophagus. It can also help prevent the airway from becoming temporarily blocked during sleep, reducing the risk of conditions like sleep apnea.
