A nurse is caring for an older adult client who is postoperative. Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to collect data about the client's progress.

Rationale for Correct Answer: Potential Condition: Delirium: The client has acute onset of confusion and disorientation to time and place, with intact self-orientation. Displays disorganized thinking, incoherent speech, inattention, and restlessness, which are hallmark signs of delirium. Behavior changes developed suddenly (prior evening), consistent with an acute condition, rather than chronic cognitive decline. Additional factors: post-operative status, dehydration (250 mL intake vs. 2,500 mL output), fever, and hypotension, all of which are known triggers of delirium in older adults. Actions to Take: Encourage family members to stay with the client: Provides reassurance, helps orient the client, and reduces agitation. Monitor the client's fluid intake and output: The client is at risk for dehydration, which can worsen delirium and hemodynamic instability. Parameters to Monitor: BUN level: Monitors hydration status and renal function, which may contribute to delirium. Sleep-wake cycle: Disruption in sleep is a common symptom and indicator of delirium progression or improvement. Rationale for Incorrect Options: Alzheimer’s disease: Causes gradual cognitive decline over months to years, not sudden post-operative changes. Depression: May cause withdrawal, low mood, and reduced activity, but does not cause sudden disorientation or incoherent speech. Generalized anxiety disorder: Causes worry and tension but does not produce acute confusion or disorganized thought. Assist the client to identify coping skills: Helpful for chronic anxiety or stress, but not the priority in acute delirium. Request a prescription for benzodiazepine: Benzodiazepines are generally avoided in delirium as they may worsen confusion, except in alcohol or sedative withdrawal. Encourage the client to exercise: Not appropriate while the client is acutely confused, restless, and at high risk for falls. Weight loss: Not immediately relevant in acute post-operative delirium. Fall risk: Important, but monitoring fluid status and cognitive function takes priority for delirium management. Suicidal ideation: Not indicated in this scenario; the client’s acute confusion, not mood disorder, is the primary concern.
