A client who has a diagnosis of depression is attending group therapy. During the group meeting, the nurse asks each member to identify one goal for the day. When it is the client's turn, she does not respond. Which of the following actions should the nurse take before repeating the request to the client?

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.

Choice A reason: Fine motor tremors are a common early side effect of lithium, affecting cerebellar function due to its narrow therapeutic index and sodium channel interactions. These typically subside within weeks as the body adjusts to stable serum levels (0.5–1.2 mEq/L), making this an accurate, reassuring response.

Choice B reason: Dismissing tremors as unimportant unless persistent for a month is incorrect. Lithium tremors, linked to cerebellar effects, often resolve sooner, but persistent tremors may indicate toxicity (levels >1.5 mEq/L), risking neurological damage. This response delays necessary monitoring, ignoring the drug’s neuropharmacological impact.

Choice C reason: Acknowledging tremors but implying the client’s concern is excessive is dismissive. Tremors result from lithium’s cerebellar effects, a legitimate side effect. This response fails to educate about the expected resolution timeline or need for monitoring, risking patient distrust and ignoring the drug’s neurobiological effects.

Choice D reason: Labeling tremors as a potential toxicity sign is misleading, as early fine tremors are typically benign, not indicative of toxicity (>1.5 mEq/L), which involves severe symptoms like confusion. This overstates risk, causing unnecessary alarm, and does not address the common, transient cerebellar effect of lithium.
