A nurse is performing an admission assessment on a client who has been diagnosed with schizophrenia. Which of the following findings should the nurse identify as a negative symptom?

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 D: "If suspicion of abuse exists, then reporting is mandatory."

Choice A rationale:

If the potential abuser commits to stopping the abuse, healthcare workers are not required to report it. Rationale: This statement is incorrect. Healthcare workers are mandated reporters, and their primary responsibility is to protect the safety and well-being of the child. Regardless of whether the potential abuser commits to stopping the abuse, suspicion of abuse requires reporting.

Choice B rationale:

Evidence must exist before reporting. Rationale: This statement is incorrect. While concrete evidence can strengthen a case, it is not a prerequisite for reporting suspected child abuse. Reporting is based on reasonable suspicion, not proof. Healthcare workers should err on the side of caution and report any concerns.

Choice C rationale:

I don't want to defame someone if the report is false. Rationale: This statement is incorrect. Reporting suspected child abuse is not about defaming someone, but rather about ensuring the safety of the child. Reporting is a part of the legal and ethical obligations of healthcare workers to protect vulnerable individuals.

Choice D rationale:

If suspicion of abuse exists, then reporting is mandatory. Rationale: This statement is correct. Healthcare workers are mandated reporters and have a duty to report suspected child abuse to appropriate authorities. Reporting is necessary when there is reasonable suspicion, even if definitive evidence is not yet present.
