A nurse is caring for an older adult client who was alert and oriented at admission but now seems increasingly restless and intermittently confused. Which of the following actions should the nurse take to address the client's safety needs?

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:

Circumstantiality refers to a communication pattern where the individual provides excessive, unnecessary details before reaching the point. In this scenario, the patient's response is not characterized by providing excessive details but rather by the use of words that sound alike but have no meaningful connection.

Choice B rationale:

Clang association is a communication pattern where the individual's speech is characterized by rhyming or the repetition of words that sound similar but lack logical connection. The patient's response, "This is a new day in May and I can't wait to play," demonstrates this pattern, as the words "May" and "play" rhyme but don't form a coherent sentence.

Choice C rationale:

Tangentiality refers to a communication pattern where the individual goes off-topic and never returns to the original subject. The patient's response, while seemingly off-topic, is not a clear example of tangentiality, as the words used are related in a rhyming manner rather than being entirely unrelated.

Choice D rationale:

Neologism refers to the creation of new words or phrases that are not part of any recognized language. The patient's response does not involve the creation of entirely new words; instead, it involves the use of existing words that rhyme but lack a coherent connection.
