According to Bowen's theoretical approach to therapy, which of the following should the nurse recognize as a concept of a functional family interaction pattern?

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 answers are choices B and D: "Offer ideas for ways to distract or redirect the client." and "Educate the spouse about the availability of adult care as a respite."

Choice A rationale:

Suggesting a long-term care facility should not be the first action. Early-stage Alzheimer's clients can often remain at home with proper support, and suggesting institutionalization might not be appropriate at this stage.

Choice B rationale:

This is a correct choice. Engaging the client with Alzheimer's in activities that distract or redirect their focus can be helpful. This approach can alleviate the spouse's concerns and provide some relief from exhaustion.

Choice C rationale:

While discussing dementia care options with the spouse is important, it might not directly address the spouse's current exhaustion and feelings of helplessness.

Choice D rationale:

This is a correct choice. Educating the spouse about adult care options for respite can provide much-needed breaks for the caregiver. Caring for someone with Alzheimer's can be emotionally and physically draining, so respite care can offer temporary relief.

Choice E rationale:

Suggesting anti-anxiety drugs for the spouse is not the best first action. While addressing caregiver stress is important, suggesting medication should come after considering other supportive measures.
