A nurse is planning care for a client who is withdrawing from alcohol. Which of the following medications should the nurse plan to administer during the acute phase of alcohol withdrawal?
Varenicline
Diazepam
Disulfiram
Acamprosate
The Correct Answer is B
Choice A reason: Varenicline is a partial nicotinic acetylcholine receptor agonist used for smoking cessation. It reduces cravings and withdrawal symptoms associated with nicotine dependence but has no role in managing acute alcohol withdrawal. Alcohol withdrawal involves hyperexcitability of the central nervous system due to the sudden absence of GABAergic stimulation, and Varenicline does not address this pathophysiology.
Choice B reason: Diazepam, a benzodiazepine, is the drug of choice for acute alcohol withdrawal. Benzodiazepines enhance GABA activity, counteracting the excitatory state caused by alcohol cessation. They reduce the risk of seizures, delirium tremens, and autonomic instability. Diazepam’s long half-life provides smoother withdrawal coverage and reduces rebound symptoms. Clinically, it is administered under close monitoring to titrate sedation and prevent complications.
Choice C reason: Disulfiram is an aversive agent used for long-term alcohol abstinence. It inhibits aldehyde dehydrogenase, causing accumulation of acetaldehyde when alcohol is consumed, leading to unpleasant symptoms such as flushing, nausea, and palpitations. However, it is contraindicated during acute withdrawal because it does not relieve withdrawal symptoms and may worsen the client’s condition if alcohol is ingested.
Choice D reason: Acamprosate is used for maintaining abstinence after detoxification. It modulates glutamatergic neurotransmission, reducing cravings and preventing relapse. However, it is not effective in treating acute withdrawal symptoms such as tremors, seizures, or delirium. Its role is supportive in long-term recovery, not immediate stabilization.

Correct Answer is C
Explanation
Choice A reason: Placing a soft rug in front of the client’s chair increases the risk of tripping and falling. Clients with dementia often have impaired judgment, coordination, and gait instability. Loose rugs are a well-known environmental hazard in home safety assessments, and therefore this intervention is unsafe.
Choice B reason: Setting the water heater at 140° F is dangerous because clients with dementia may not recognize the risk of burns. Safe water heater settings are typically recommended at or below 120° F to prevent scalding injuries. High temperatures pose a significant safety risk for cognitively impaired individuals.
Choice C reason: Encouraging a 1-hour nap in the afternoon is beneficial. Clients with dementia often experience fatigue, irritability, and sundowning (worsening confusion in the evening). A structured rest period helps reduce agitation, improves mood, and supports overall functioning. This intervention promotes both safety and comfort.
Choice D reason: Limiting fluid intake after the evening meal can lead to dehydration and urinary tract infections. While nighttime incontinence may be a concern, restricting fluids is not recommended because hydration is critical for cognitive and physical health. Instead, toileting schedules and protective measures should be used.
Correct Answer is ["A","C","D","F"]
Explanation
Choice A reason: Sitting with the client during mealtimes is an essential intervention because clients with bipolar disorder, especially during manic episodes, often have poor appetite and difficulty focusing long enough to eat. Direct support ensures nutritional intake, prevents further weight loss, and provides structure. It also reduces the risk of malnutrition and dehydration, which are common complications in manic states.
Choice B reason: Turning on the television for the client is not therapeutic. Clients in manic episodes are easily overstimulated, and television can increase agitation, distractibility, and hyperactivity. Instead of calming the client, it may worsen confusion and disorientation. Therefore, this intervention is inappropriate.
Choice C reason: Removing sharp objects from the client’s room is a critical safety measure. Clients with bipolar disorder experiencing mania may act impulsively, and the risk of self-harm or accidental injury is high. Ensuring the environment is free of dangerous objects reduces the likelihood of harm and supports safe management of the client’s agitation.
Choice D reason: Observing the client every 15 minutes is necessary for safety monitoring. The client is hyperactive, confused, and disoriented, which increases the risk of injury, aggression, or unpredictable behavior. Frequent observation allows early detection of escalating agitation and ensures timely intervention. This is a standard safety protocol in acute psychiatric care.
Choice E reason: Providing a low-protein diet is not indicated. Clients with bipolar disorder do not require protein restriction; in fact, adequate protein intake is important for maintaining energy and nutritional balance. Restricting protein could worsen malnutrition and weight loss. This intervention is inappropriate.
Choice F reason: Offering the client physical activities is beneficial because it provides a safe outlet for excess energy during manic episodes. Structured physical activity helps reduce agitation, channel hyperactivity, and promote better sleep. It also decreases restlessness and supports overall emotional regulation. Activities should be simple, noncompetitive, and safe to avoid overstimulation.
