A nurse is assessing an adolescent female client who has anorexia nervosa. Which of the following findings should the nurse expect?

Metrorrhagia.

Tachycardia.

Hyperkalemia.

Constipation.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is C

Explanation

Choice A rationale:

Praying and using relaxation techniques when experiencing rapid breathing are effective stress management strategies. These techniques help manage the body's stress response and promote relaxation.

Choice B rationale:

Journaling is a constructive way to manage stress, especially when verbal expression is difficult. It allows individuals to reflect on their thoughts and emotions, leading to a sense of relief.

Choice C rationale:

"Fixing a pot of coffee" when anxious is the least effective technique mentioned. Consuming large amounts of caffeine can exacerbate anxiety symptoms by increasing heart rate and contributing to a sense of restlessness and nervousness.

Choice D rationale:

Engaging in physical exercise when experiencing tension in the neck is a productive strategy. Exercise promotes the release of endorphins, which are natural mood lifters and stress reducers.

A. Tachycardia. B. Tremors. C. Hallucinations. D. Hypotension. E. Seizures.

Correct Answer is ["A","B","C","E"]

Explanation

Choice A rationale:

Tachycardia (rapid heart rate) is a potential physical symptom of alcohol withdrawal. When alcohol-dependent individuals suddenly stop or reduce their alcohol intake, it can lead to increased sympathetic nervous system activity, resulting in elevated heart rate.

Choice B rationale:

Tremors (shakes) are common during alcohol withdrawal due to the suppression of the central nervous system by alcohol. Abrupt cessation of alcohol can lead to overactivity in the nervous system, resulting in tremors.

Choice C rationale:

Hallucinations can occur during alcohol withdrawal and are usually visual or tactile in nature. These hallucinations are often referred to as alcoholic hallucinosis and can be distressing for the individual experiencing them.

Choice E rationale:

Seizures can be a severe consequence of alcohol withdrawal. Known as alcohol withdrawal seizures, these episodes can occur within the first 48 hours after cessation of heavy alcohol consumption and are attributed to the hyperexcitability of the central nervous system.

Choice D rationale:

Hypotension (low blood pressure) is not typically associated with alcohol withdrawal. In fact, alcohol withdrawal often leads to an increase in blood pressure and heart rate due to the hyperactivity of the sympathetic nervous system.
