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 D
Explanation
The correct answer is choice D: "Remain with the client in his room for a while."
Choice D rationale:
This choice is the correct answer because when a client is experiencing panic-level anxiety, their immediate need is for support and reassurance. Staying with the client helps establish a sense of safety and demonstrates the nurse's presence, which can help reduce anxiety. Providing a calming and supportive presence is a therapeutic nursing intervention in this situation.
Choice A rationale:
Medicating the client with a sedative might be appropriate in some cases of severe anxiety, but it should not be the first action taken. Non-pharmacological interventions, such as offering emotional support, should be prioritized before resorting to medication.
Choice B rationale:
Joining a therapy group might be beneficial for the client in the future, but during the acute phase of panic-level anxiety, the client might not be in a state to actively participate and engage in group therapy. Immediate individual attention is necessary.
Choice C rationale:
While suggesting that the client rest in bed could be helpful for relaxation, it might not be sufficient to address the intensity of panic-level anxiety. The client might not be able to rest or calm down without more direct support from the nurse.
Correct Answer is ["A","B","E"]
Explanation
Answer and explanation
The correct answers are choices A. Depression, B. Obsessive-compulsive disorder, E. Anxiety.
Choice A rationale:
Depression commonly coexists with eating disorders. The individual's distorted body image, feelings of low self-worth, and dietary restrictions can contribute to the development of depressive symptoms.
Choice B rationale:
Obsessive-compulsive disorder (OCD) often occurs alongside eating disorders. The obsessions and compulsions seen in OCD can overlap with behaviors related to food, eating rituals, and body image, reinforcing the eating disorder pathology.
Choice C rationale:
Schizophrenia is not typically considered a comorbidity of eating disorders. Schizophrenia involves disruptions in thought processes, emotions, and perceptions, which are distinct from the cognitive distortions and behaviors associated with eating disorders.
Choice D rationale:
Breathing-related sleep disorder is not a commonly recognized comorbidity of eating disorders. While sleep disturbances might occur in individuals with eating disorders due to physical discomfort or anxiety, a specific link to breathing-related sleep disorder is less established.
Choice E rationale:
Anxiety is a well-recognized comorbidity of eating disorders. Anxiety often accompanies the intense fears, worries, and preoccupations related to body weight, shape, and eating behaviors that are characteristic of eating disorders.
