A nurse on a mental health unit notices that a client is becoming increasingly agitated and throws a table when he is unable to select the television (TV) channel. Which of the following should be a priority action by the 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:

The nurse should prioritize the safety and well-being of both clients involved. Assisting the client with late-stage Alzheimer's disease to the correct room is important to prevent any further confusion or distress. Alzheimer's disease often causes cognitive impairment, memory loss, and disorientation, which can lead to situations where the individual may not recognize their surroundings or the people around them. Guiding the client back to their own room will help reduce confusion, agitation, and potential conflicts with other clients.

Choice B rationale:

Medicating the patient with antipsychotics is not the most appropriate initial action in this situation. Antipsychotic medications are often used to manage severe behavioral disturbances associated with conditions like schizophrenia or dementia, but their use should be carefully considered due to potential side effects. In this scenario, addressing the immediate situation and guiding the client back to their room is more appropriate than resorting to medication.

Choice C rationale:

Moving the client to a room at the end of the hall is not the best choice because it doesn't directly address the current situation. While changing the client's room might be considered in some cases to reduce agitation or wandering, it's not the immediate action needed when the client is found in another client's bed. Guiding the client to the correct room is the priority.

Choice D rationale:

Placing the client in restraints is not an appropriate choice in this situation. Restraints should only be used as a last resort for ensuring the safety of the client or others when less restrictive interventions have failed. Placing a client with Alzheimer's disease in restraints can be traumatic and lead to increased agitation and psychological distress.
