The following statement best describes which phase in the cycle of battering: "The woman senses that the man's tolerance for frustration is declining. He becomes angry with little provocation but may be quick to apologize. She may just try to stay out of his way." The nurse recognizes this statement to be which of the following phases?

Choice A rationale:

The correct choice. In this situation, the nurse's priority is to gather information and provide emotional support. By asking the spouse to share their concerns, the nurse opens up a channel of communication and shows empathy, creating an opportunity to address the spouse's worries and provide reassurance.

Choice B rationale:

While the sentiment that crying can be cathartic and relieving is true, this response does not directly address the spouse's concern or encourage them to share their feelings. It's important to focus on the spouse's feelings rather than just explaining the benefits of crying.

Choice C rationale:

Assuming that the husband is making progress without knowing the specifics of the situation can come across as dismissive of the spouse's concerns. It's important to validate the spouse's emotions and provide support, rather than making assumptions about the husband's progress.

Choice D rationale:

Asking whether the husband said something to upset the spouse might be relevant, but it does not address the spouse's expressed concern about their husband. This response may not foster open communication and emotional support as effectively as choice A.

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.
