A nurse is talking with a client diagnosed with schizophrenia. Suddenly the client states, "I'm frightened. Do you hear that? The voices are telling me to do terrible things." Which of the following responses by the nurse is appropriate?

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.

The correct answer is choice B. A room containing personal belongings.

Choice A rationale:

A room without a window would likely be isolating and could contribute to feelings of confusion and disorientation in a cognitively impaired individual. Natural light from windows helps regulate the circadian rhythm and provides a sense of time, which is crucial for maintaining a therapeutic environment.

Choice B rationale:

A room containing personal belongings is the correct choice. Familiar items from home can provide comfort and a sense of familiarity, reducing anxiety and agitation in cognitively impaired individuals. These belongings can act as cues for memory recall and assist in maintaining a connection to their personal identity.

Choice C rationale:

A room adjacent to the nursing station might lead to increased noise and disruption for the client. Cognitively impaired individuals often benefit from a quiet and calm environment, which would not be ensured in a room close to a potentially busy nursing station.

Choice D rationale:

A room with dim lighting can exacerbate confusion and disorientation in cognitively impaired individuals. Adequate lighting is essential for maintaining a safe and structured environment, as poor lighting can lead to falls and increased disorientation.
