A nurse is caring for a client who has late-stage Alzheimer's disease and is hospitalized for treatment of the flu. During the night shift, the client is found climbing into the bed of another client who becomes upset and scared. Which of the following actions should the nurse take?

The correct answer is Choice D

Choice A rationale: Metrorrhagia, or irregular uterine bleeding, is not typically associated with anorexia nervosa. Instead, amenorrhea is more common due to hypothalamic suppression from low body fat and caloric intake. The hypothalamus reduces gonadotropin-releasing hormone (GnRH), leading to decreased luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which suppresses ovulation and menstruation. Estrogen levels fall below normal (typically 30–400 pg/mL), disrupting endometrial stability. Thus, bleeding is less likely than complete menstrual cessation.

Choice B rationale: Tachycardia is not expected in anorexia nervosa; bradycardia is more common due to metabolic adaptation and reduced cardiac workload. The body conserves energy by lowering heart rate, often below 60 bpm. Malnutrition leads to decreased thyroid hormone (T3), reduced sympathetic tone, and myocardial atrophy. Electrolyte imbalances and hypovolemia further depress cardiac output. Tachycardia may occur in refeeding syndrome or acute stress, but chronically, the heart rate is typically slow due to adaptive mechanisms.

Choice C rationale: Hyperkalemia is rare in anorexia nervosa; hypokalemia is far more common due to purging behaviors, vomiting, and diuretic or laxative abuse. Potassium levels often fall below the normal range of 3.5–5.0 mEq/L. Losses through the gastrointestinal tract and renal excretion lead to muscle weakness, arrhythmias, and fatigue. Intracellular shifts during starvation also contribute to low serum potassium. Hyperkalemia may occur transiently during tissue breakdown or renal failure but is not a hallmark finding.

Choice D rationale: Constipation is a frequent finding in anorexia nervosa due to decreased caloric intake, slowed gastrointestinal motility, and reduced fiber consumption. Starvation suppresses parasympathetic activity, leading to delayed colonic transit. Electrolyte imbalances, especially hypokalemia, further impair smooth muscle contraction. Normal bowel frequency ranges from three times per week to three times per day; anorexic clients often fall below this due to systemic hypometabolism. Constipation may also be exacerbated by dehydration and laxative dependence.

Choice A rationale:

Periods of elation with unusual talkativeness. Rationale: While periods of elation with unusual talkativeness can be associated with certain mental health conditions, such as bipolar disorder, they are not specific to schizophrenia. These symptoms are more indicative of mania, which is characteristic of bipolar disorder.

Choice B rationale:

Recurrent thoughts of past trauma. Rationale: Recurrent thoughts of past trauma can be associated with various mental health disorders, including post-traumatic stress disorder (PTSD), but they are not specific to schizophrenia. Schizophrenia is primarily characterized by disturbances in thought processes, perception, and behavior.

Choice C rationale:

Preoccupied with folding clothes. Rationale: Preoccupation with folding clothes is not a hallmark symptom of schizophrenia. Schizophrenia is characterized by symptoms such as hallucinations, delusions, disorganized thinking, and impaired social functioning.

Choice D rationale:

Invents words that have no meaning. Rationale: This statement is correct. Inventing words that have no meaning, also known as "neologisms," is a symptom often observed in individuals with schizophrenia. Neologisms are a manifestation of disorganized thinking and communication.
