A nurse is providing education to a client who is scheduled for a left knee arthroplasty. Which of the following statements regarding informed consent indicates client understanding of the teaching?

Choice A reason: Increased energy and motivation signal improvement in major depressive disorder, countering fatigue and anhedonia. Serotonin and norepinephrine rebalance, often from treatment, restores drive and engagement, reflecting neurochemical stabilization in the brain’s limbic system, critical for mood regulation and recovery.
Choice B reason: Self-doubt in decision-making reflects persistent depressive symptoms, like low self-esteem and cognitive impairment. Negative thought patterns, driven by altered prefrontal cortex activity, indicate ongoing depression, not improvement, requiring adjusted interventions to address these neurocognitive deficits in major depressive disorder.
Choice C reason: Sleeping 12 hours daily indicates hypersomnia, a depressive symptom, suggesting no improvement. Disrupted circadian rhythms and serotonin dysregulation cause excessive sleep, contrasting with recovery signs like normalized sleep patterns. This reflects persistent neurochemical imbalances hindering mood stabilization in depression.
Choice D reason: Social isolation is a core depressive symptom, driven by anhedonia and low mood, indicating no improvement. Withdrawal reflects ongoing dopamine and serotonin imbalances, preventing social engagement. Recovery involves increased interaction, making isolation a sign of persistent major depressive disorder.

Choice A reason: Assigning all staff to the emergency department disrupts care for existing inpatients and may overwhelm ED operations. Staff allocation should follow a triage plan, balancing hospital-wide needs. This action is impractical and risks neglecting other patients, making it less effective than preparing resources.
Choice B reason: Preparing to discharge stable clients frees up beds for incoming casualties, optimizing hospital capacity during a mass casualty event. This aligns with disaster protocols, ensuring resources are available for critical patients. It supports efficient triage and care delivery, making it the correct action.
Choice C reason: Canceling all elective surgeries immediately is premature without assessing the event’s scope. Some surgeries may continue if resources allow, per disaster protocols. This action disrupts hospital operations unnecessarily and is less urgent than preparing beds for casualties, making it inappropriate.
Choice D reason: Requesting ventilators assumes specific needs without assessing the casualty event’s nature. Ventilators may not be immediately required, and resource allocation should follow triage protocols. Preparing beds is a more immediate and versatile action, making this choice less prioritized in the initial response.
