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:
This statement requires intervention by the charge nurse. The nurse is making a judgmental suggestion to the client about how they should approach their marital issues. The nurse's role is to provide support, empathy, and open-ended questions that allow the client to explore their feelings and thoughts. Making a directive statement like this can be perceived as controlling and dismissive of the client's feelings.
Choice B rationale:
Relationship difficulties being stressful and requiring effort to resolve is an appropriate and empathetic response from the nurse. This acknowledges the client's struggles and offers validation without imposing a particular solution.
Choice C rationale:
Developing a plan for communication is a constructive approach that helps the client address their concerns. This response is within the nurse's scope of practice and promotes problem-solving and effective communication between partners.
Choice D rationale:
Encouraging the client to share more about their concerns regarding their marriage is a therapeutic response. It shows active listening and facilitates the client's exploration of their feelings, which is an essential aspect of the nursing role in a therapeutic relationship.
Correct Answer is D
Explanation
Choice D rationale:
Setting limits on the client's behavior and maintaining consistency is essential when dealing with a client experiencing a manic episode. Manic episodes are characterized by impulsive and often disruptive behaviors. By setting clear limits, the nurse establishes boundaries that help manage the disruptive behavior and maintain a safe and therapeutic environment. Consistency in approach is vital to avoid confusion and to provide the client with a sense of stability during a time when their judgment and impulse control might be impaired.
Choice A rationale:
Warning the client that further disruptions will result in seclusion might escalate the situation and potentially worsen the client's agitation. It's crucial to use non-confrontational approaches when dealing with clients experiencing manic episodes to prevent increased agitation and aggression.
Choice B rationale:
Ignoring the client's behavior is not a suitable approach, as it could lead to a deterioration of the situation and potentially compromise the safety and well-being of both the client and others on the unit. It's important to address disruptive behavior promptly and appropriately.
Choice C rationale:
Asking the client to recommend consequences for her disruptive behavior might not be effective during a manic episode. Clients in a manic state might not have a realistic or rational perspective on their behavior, and involving them in determining consequences could lead to unreasonable outcomes.
