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. Use clarification to determine what the patient is feeling. B. Never break constant eye contact with the patient. C. Move the patient to a private area so the conversation will not be disturbed and cannot be seen. D. Speak to the patient using an authoritative voice and ask them, "Why are you acting this way?”

Correct Answer is A

Explanation

Choice A rationale:

When dealing with an angry and aggressive client, using clarification is an essential communication technique. It involves asking open-ended questions to better understand the patient's emotions and concerns, which can help defuse the situation and provide insight into the underlying issues.

Choice B rationale:

Maintaining constant eye contact can be interpreted as confrontational or aggressive behavior, potentially escalating the client's aggression. It's important to maintain a respectful distance and avoid behaviors that could exacerbate the situation.

Choice C rationale:

Moving the patient to a private area is a reasonable approach if the environment is contributing to the patient's agitation. However, the primary concern should be the safety of both the patient and the staff. Privacy can be important, but it shouldn't compromise safety.

Choice D rationale:

Speaking to the patient with an authoritative voice and asking "why" questions can escalate the situation further. It may come across as confrontational and provoke a defensive reaction from the patient. Open-ended questions that encourage the patient to express their feelings can be more effective in de-escalation.
