Final answer:
When a patient is unable to sleep in the lateral position after surgery, it may indicate an increased risk of developing complications, such as airway obstruction or sleep apnea.
Step-by-step explanation:
When a patient is unable to sleep in the lateral position after surgery, it may indicate an increased risk of developing complications, such as airway obstruction or sleep apnea. Sleeping on one's back can lead to the airway becoming temporarily blocked during sleep, resulting in sleep apnea. This can be a concern for postoperative patients, as it can affect their breathing and oxygenation. Therefore, the nurse should closely monitor the patient and assess for signs of airway obstruction, such as snoring, gasping, or pauses in breathing during sleep.
