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 D

Explanation

Choice A rationale:

Establishing trust with a caregiver in just five days is a challenging and unrealistic expectation for a child diagnosed with autistic spectrum disorder (ASD). Building trust takes time, especially for individuals with ASD who may struggle with social interactions and forming connections.

Choice B rationale:

Participating in a team sport with peers by day 4 might be too ambitious for a child with ASD. Children with ASD often require gradual exposure and support to engage in social activities, and such rapid participation might lead to anxiety and discomfort.

Choice C rationale:

While communication goals are important for children with ASD, expecting them to communicate all needs verbally by discharge might not be realistic. Many children with ASD use alternative forms of communication, such as gestures or assistive devices, which should also be considered as valid modes of expression.

Choice D rationale:

The realistic outcome for a child diagnosed with ASD is that they will perform most self-care tasks independently. ASD often affects social and communication skills, but children can learn and develop the ability to manage self-care tasks with proper support and intervention. This outcome aligns with the developmental trajectory of children with ASD.

A. "I pray when I begin to breathe fast.” B. "I journal when I find it difficult to talk.” C. "I fix myself a pot of coffee when I get anxious.” D. "I exercise when my neck is tense.”

Correct Answer is C

Explanation

Choice A rationale:

Praying and using relaxation techniques when experiencing rapid breathing are effective stress management strategies. These techniques help manage the body's stress response and promote relaxation.

Choice B rationale:

Journaling is a constructive way to manage stress, especially when verbal expression is difficult. It allows individuals to reflect on their thoughts and emotions, leading to a sense of relief.

Choice C rationale:

"Fixing a pot of coffee" when anxious is the least effective technique mentioned. Consuming large amounts of caffeine can exacerbate anxiety symptoms by increasing heart rate and contributing to a sense of restlessness and nervousness.

Choice D rationale:

Engaging in physical exercise when experiencing tension in the neck is a productive strategy. Exercise promotes the release of endorphins, which are natural mood lifters and stress reducers.
