A nurse is assessing a client who is sharing information regarding concerns about their marriage. The client states "My spouse and I argue most times." Which of the following statements by the nurse requires intervention by the charge nurse?

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:

This choice describes tertiary prevention, which focuses on minimizing the consequences of an existing disorder or preventing further deterioration. It is not directly related to primary prevention, which addresses the prevention of the onset of disorders.

Choice B rationale:

This choice corresponds to secondary prevention, which involves early intervention to minimize the impact of an illness that has already begun. It aims to reduce the prevalence and duration of the illness but is not the primary focus of primary prevention.

Choice C rationale:

The correct choice. Primary prevention focuses on reducing the incidence of mental disorders within the population. It involves strategies that target the entire population or specific high-risk groups to prevent the initial development of mental health issues. These strategies may include public health campaigns, education, and interventions to promote mental well-being and resilience.

Choice D rationale:

This choice describes the process of early identification and initiation of treatment, which is a component of secondary prevention. It aims to prevent the progression of existing problems rather than preventing the initial development of mental disorders.
