Seasonal Affective Disorder is a disturbance of mood and behavior accompanied by at least 5 key features for at least 2 weeks.

Choice A reason: Mild delirium involves acute confusion and impaired judgment due to cerebral dysfunction, often from metabolic or infectious causes. Accompanying the client ensures safety, as disorientation increases wandering or injury risk. Supervision mitigates risks from altered cognition while allowing mobility, supporting cerebral recovery without exacerbating confusion.

Choice B reason: Restricting the client to the unit may increase agitation, as delirium’s neurochemical imbalances, like acetylcholine deficiency, heighten restlessness. While safety is critical, blanket restriction ignores the potential benefits of supervised movement, which can reduce stress and improve cerebral perfusion, making this less appropriate than supervised accompaniment.

Choice C reason: Assessing motives may clarify intent but delays addressing immediate safety in delirium, where confusion stems from cerebral dysfunction, such as hypoxia or electrolyte imbalance. The client’s impaired judgment requires supervision over exploration of motives, as disorientation increases risk of harm, making this a secondary action.

Choice D reason: Allowing an unsupervised walk is unsafe in delirium, as acute cognitive impairment from neurotransmitter imbalances or metabolic disturbances increases wandering or injury risk. Without supervision, the client may become disoriented or lost, exacerbating cerebral stress. Accompanied walks better balance safety and mobility in this condition.

Choice A reason: Monitoring vital signs is critical in withdrawal delirium, as it is a medical emergency involving autonomic hyperactivity from alcohol or drug cessation. Dehydration and electrolyte imbalances elevate heart rate and blood pressure, risking seizures or cardiovascular collapse. Regular monitoring detects instability early, guiding fluid replacement and medication to stabilize cerebral and systemic function.

Choice B reason: Keeping the room dark may reduce sensory overload in withdrawal delirium, but it does not address physiologic instability like dehydration or autonomic hyperactivity. Darkness may calm agitation but risks disorientation in a confused patient, as visual cues aid reality testing. This choice is less critical than monitoring vital signs for ensuring systemic stability.

Choice C reason: Withholding oral fluids is contraindicated in withdrawal delirium, as dehydration exacerbates symptoms like confusion and autonomic instability. Fluid loss from sweating or vomiting, common in withdrawal, disrupts electrolyte balance and cerebral perfusion. Providing fluids corrects hypovolemia, making this choice scientifically inappropriate for maintaining physiologic stability in this critical condition.

Choice D reason: Applying ice to the tongue may reduce swelling from trauma, but it does not address the systemic instability of withdrawal delirium, such as dehydration or autonomic hyperactivity. Tongue swelling is a secondary issue compared to life-threatening risks like seizures or arrhythmias, which require monitoring vital signs and fluid management for stabilization.
