A school nurse is speaking to the mother of a 16-year-old male adolescent. The mother has concerns about her son. Which of the following statements by the mother should indicate to the nurse that the adolescent is at risk for suicide?

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:

The nurse's approach of sitting with the client and offering simple, direct information is appropriate for a newly admitted client diagnosed with severe depression. This approach allows the nurse to establish a therapeutic rapport and provide the client with essential information in a clear and concise manner. People with severe depression often have difficulty processing complex information, so providing simple and direct information can enhance their understanding and alleviate any feelings of overwhelm.

Choice B rationale:

Explaining the unit policies and answering the client's questions might be overwhelming for someone with severe depression during their initial orientation. People experiencing depression often have difficulties with concentration and retaining information due to cognitive impairment. Presenting them with detailed policies and procedures might increase their anxiety and hinder their ability to absorb the information effectively.

Choice C rationale:

Having the client attend group therapy immediately might not be the best approach for someone with severe depression upon admission. Group therapy could be beneficial later in the treatment process, but initially, the client might not be emotionally ready to engage in group interactions. It's essential to establish a one-on-one therapeutic relationship and provide a stable environment before introducing them to group settings.

Choice D rationale:

Taking the client on a tour of the unit and introducing them to all the staff members on duty might be overwhelming and anxiety-inducing for someone with severe depression. It's crucial to approach the client with sensitivity and respect their emotional state. Introducing them to multiple staff members might increase their social anxiety and make them feel exposed, leading to further distress.
