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.
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 A
Explanation
Choice A rationale:
The statement "You are feeling very depressed. I felt the same way when I decided to leave my husband." is a non-therapeutic statement that demonstrates sympathy. The nurse is sharing personal experiences, which can shift the focus from the client's feelings to the nurse's own experiences.
Choice B rationale:
The statement "I can understand you are feeling depressed. It was a difficult decision. I'll sit with you." is a therapeutic response that offers support and empathy without diverting the focus to the nurse's experiences. The nurse's willingness to sit with the client is a positive aspect of this response.
Choice C rationale:
The statement "You seem depressed. It was a difficult decision to make. Would you like to talk about it?" is a therapeutic response that acknowledges the client's feelings, offers support, and invites further conversation. This response encourages the client to express themselves.
Choice D rationale:
The statement "I know this is a difficult time for you. Would you like medication for anxiety?" acknowledges the client's difficulties but immediately offers medication as a solution. While medication can be a valid option, it's important to prioritize open communication and emotional support before suggesting medication.
Correct Answer is A
Explanation
The correct answer is choice A: Set limits for the relationship.
Choice A rationale:
Setting limits for the therapeutic relationship (Choice A) is an essential nursing action. Boundaries help create a safe and structured environment, ensuring that both the nurse and client maintain appropriate roles. Limits prevent overstepping boundaries that could compromise the therapeutic alliance.Setting limits for the relationship is an essential part of establishing a therapeutic relationship in a mental health setting. This helps to maintain professional boundaries and ensures that the relationship remains focused on the client’s needs and therapeutic goals.
Choice B rationale:
Engaging in affectionate interactions with the client (Choice B) is not appropriate in a therapeutic relationship. Professionalism and maintaining appropriate boundaries are crucial in psychiatric nursing. Affectionate interactions could blur the lines between the therapeutic relationship and personal relationships, potentially harming the client's progress.
Choice C rationale:
Promoting the use of transference by the client (Choice C) is not a suitable approach. Transference occurs when a client projects feelings and emotions onto the nurse based on past experiences. While it can be valuable to explore transference, actively promoting it could lead to confusion and misunderstandings in the therapeutic relationship.
Choice D rationale:
Instructing the client on how they should behave (Choice D) is contrary to the principles of a therapeutic relationship. The therapeutic relationship is client-centered, where the nurse supports the client's self-discovery and growth. Directing the client's behavior undermines their autonomy and inhibits their progress.
