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 B

Explanation

The correct answer is choice B. "It sounds like you're having a difficult time."

Choice A rationale:

"How long has this been going on?" This question focuses on the duration of the client's symptoms, which might not be the most appropriate response at this point. The client's immediate emotional state and distress should be acknowledged before delving into the duration of the issue.

Choice B rationale:

"It sounds like you're having a difficult time." This response demonstrates empathy and understanding towards the client's emotional state. It acknowledges the client's feelings without making assumptions or probing for specific details. It provides a supportive environment for the client to open up further.

Choice C rationale:

"Have you talked to your parents about this yet?" This question assumes that the client's parents are a source of support and that the client has not yet spoken to them about their feelings. It also directs the conversation towards external parties instead of focusing on the client's immediate emotions.

Choice D rationale:

"Why do you think you are so anxious?" This question might come across as confrontational or demanding, potentially making the client defensive. It could hinder open communication and create a barrier between the nurse and the client.

A. "You need to work hard on resolving conflict with those closest to you.” B. "Let's discuss what you mean when you say that you cannot ever return to work.” C. "I notice you keep clenching your fists. Why are you doing this?” D. "Antidepressants are not your solution, but this therapy group is.”

Correct Answer is B

Explanation

Choice A rationale:

Telling the newly diagnosed cancer clients that they need to work hard on resolving conflicts with those closest to them may come across as insensitive and dismissive of their emotional struggles. Cancer diagnosis often brings about complex emotions, and this response does not acknowledge or address their concerns.

Choice B rationale:

This response acknowledges the client's statement and encourages further discussion about their feelings regarding their inability to return to work. It shows empathy and a willingness to explore their concerns, promoting open communication and emotional support.

Choice C rationale:

Commenting on the client's physical behavior without context might make them uncomfortable or self-conscious. The nurse's observation about fist clenching should be addressed more delicately if relevant, and the focus should be on the emotional aspect rather than the physical behavior.

Choice D rationale:

Dismissing the potential benefit of antidepressants and promoting the therapy group might undermine the client's feelings and choices. While group therapy can be beneficial, this response overlooks the potential need for a multifaceted approach to treatment, which could include therapy and medication.
