A nurse is assessing an adolescent female client who has anorexia nervosa. Which of the following findings should the nurse expect?
A. Metrorrhagia.
Metrorrhagia (Choice A) refers to irregular or excessive uterine bleeding between menstrual periods. While anorexia nervosa can disrupt menstrual cycles, causing amenorrhea, metrorrhagia is not a common associated finding.
B. Tachycardia.
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.
C. Hyperkalemia.
Hyperkalemia (Choice C), which is elevated levels of potassium in the blood, is not a typical finding in anorexia nervosa. Electrolyte imbalances in anorexia more commonly involve decreased potassium levels (hypokalemia) due to inadequate intake and excessive purging.
D. Constipation.
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.

Full Explanation
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.

A nurse in a mental health clinic is attempting to develop a therapeutic relationship with a client. Which of the following should be the appropriate action by the nurse?
A. Set limits for the relationship.
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.
B. Engage in affectionate interactions with the client.
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.
C. Promote the use of transference by the client.
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.
D. Instruct the client on how he should behave.
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.

A nurse is reviewing the history and physical of an adolescent client diagnosed with conduct disorder. The nurse recognizes that which of the following is an expected assessment finding of conduct disorder?
A. Death of client's father two months ago.
The client's father's recent death (Choice A) is not a typical expected assessment finding of conduct disorder. While emotional disturbances can be associated with conduct disorder, the primary characteristics involve behavioral issues rather than reactions to significant life events.
B. Adheres strictly to routines.
Adhering strictly to routines (Choice B) is not a common expected assessment finding of conduct disorder. Conduct disorder is characterized by patterns of defiant and disruptive behaviors, not necessarily a rigid adherence to routines.
C. Suspended from school several times in the past year.

Conduct disorder often involves aggressive behavior towards others, violation of rules, and disregard for the rights of others, which can lead to disciplinary actions such as school suspensions.
D. Experiences frequent facial tics.
Experiencing frequent facial tics (Choice D) is not a typical expected assessment finding of conduct disorder. Facial tics are associated with conditions like Tourette's syndrome or other tic disorders, not conduct disorder.

A nurse on a mental health unit is caring for a client who has generalized anxiety disorder. The client received a telephone call that was upsetting, and now the client is pacing up and down the hallways of the unit. Which of the following actions should the nurse take?
A. Instruct the client to sit down and stop pacing.
