A nurse is providing teaching to a client diagnosed with schizophrenia and is prescribed haloperidol (Haldol). Which of the following information should the nurse include in the teaching?

Choice A rationale:

Reviewing the client's toxicology laboratory report is not the priority action in this situation. While assessing toxicology can provide valuable information, the immediate concern is the client's safety due to their admission of thoughts of self-harm with a plan. Toxicology can be relevant but addressing the immediate risk takes precedence.

Choice B rationale:

Initiating suicide precautions is the priority action in this case. The client's admission of thoughts of self-harm with a plan indicates a high risk for suicide. Suicide precautions involve closely monitoring the client, removing any potential means of self-harm, and providing a safe environment. Addressing the client's immediate safety is of utmost importance.

Choice C rationale:

Making a contract with the client for eating behavior is not the priority action in this situation. While eating behavior might be a concern for some individuals with borderline personality disorder, depression, and substance abuse, the client's current statement about self-harm takes precedence. Ensuring the client's safety comes before addressing other aspects of their care.

Choice D rationale:

Administering the Hamilton Depression Scale is not the priority action in this scenario. While assessing the severity of the client's depression is important, the immediate concern is their safety due to the expressed thoughts of self-harm. Once the client's safety is ensured, further assessment and evaluation can take place.

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.
