A patient is admitted to the hospital with SOB. The nurse notices increasing confusion and combativeness during the past hour. Which of the following actions is appropriate first?

A. Put up the patient's side rails and apply soft restraints: Restraints may prevent injury but do not address the underlying cause of confusion and combativeness. Using restraints first could delay treatment of a potentially life-threatening issue. B. Assess the patient; check to see if the oxygen is flowing correctly: The first action is to assess for immediate physiological causes, such as hypoxia. Confusion and combativeness can be early signs of low oxygen levels, making assessment and ensuring oxygen delivery the priority intervention. C. Page the MD STAT: Notifying the provider is important, but immediate assessment by the nurse takes priority to identify and address urgent needs before waiting for physician orders. D. Administer an IM sedative: Sedation may temporarily calm the patient but can worsen hypoxia or respiratory distress if the underlying cause is not addressed first. It should not be the first action in acute confusion with possible hypoxia.
