A patient diagnosed with dementia associated with excessive alcohol use tells a nurse, "Last week I had to take my baby to the hospital for major surgery. That's why I've been so nervous and needed to come here." The nurse is aware that the patient has never parented any children. The symptom described can be assessed as:

Correct Answer: B

Rationale: The correct answer is B: confabulation. Confabulation is the production of fabricated or distorted memories without the conscious intention to deceive. In this case, the patient is creating a false memory about having a baby and needing to take it to the hospital, which is not based on reality. Akathisia (A) is a movement disorder associated with restlessness, not memory distortion. Intellectualization (C) is a defense mechanism involving excessive focus on facts to avoid uncomfortable emotions, not memory fabrication. Magical thinking (D) involves believing that one's thoughts can influence events, not creating false memories.

Correct Answer: A

Rationale: The correct answer is A: Fluoxetine (Prozac). Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat eating disorders and affective disorders like depression. The nurse would prepare a client teaching plan for fluoxetine to educate the client on its mechanism of action, potential side effects, proper dosing, and the importance of compliance. Diazepam and lorazepam are benzodiazepines used for anxiety and not typically indicated for eating or affective disorders. Lithium is primarily used for bipolar disorder and not specifically for eating or affective disorders.

Correct Answer: B

Rationale: The correct answer is B because accompanying the client to the bathroom is essential to prevent purging behavior associated with bulimia nervosa. By doing so, the nurse can provide support, monitor the client, and intervene if necessary to ensure the client's safety. Choice A is incorrect as it may come across as punitive and restrictive. Choice C is incorrect as it may escalate the situation and lead to confrontation. Choice D is incorrect as it suggests an alternative behavior without addressing the immediate concern of potential purging. Accompanying the client to the bathroom is the most appropriate and therapeutic response in this situation.

Correct Answer: D

Rationale: The correct answer is D: parasomnias. Parasomnias are sleep disorders involving abnormal behaviors or physical events during sleep, such as sleepwalking or night terrors. This is the correct choice because it specifically addresses the description provided in the question. A: Insomnia is characterized by difficulty falling or staying asleep, not abnormal behaviors during sleep. B: Dyssomnias are a broad category of sleep disorders affecting the timing, quality, or amount of sleep, not necessarily involving abnormal behaviors during sleep. C: Hypersomnia is a sleep disorder characterized by excessive daytime sleepiness, not abnormal behaviors during sleep. In summary, the other choices do not align with the description of sleep disorders involving abnormal behavioral or physical events during sleep, making D the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Deficient fluid volume. The patient is displaying signs of severe malnutrition and dehydration, as evidenced by significant weight loss, low blood pressure, low heart rate, and poor skin turgor. The low serum potassium and high urine specific gravity indicate dehydration. Addressing fluid volume deficiency is the top priority to stabilize the patient's condition and prevent further complications like electrolyte imbalances and organ damage. Choices A and B are important but secondary to addressing the immediate threat of dehydration. Choice D is not the priority as the patient's primary concern is physiological rather than psychological.
