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 A

Explanation

Choice A rationale:

"His cousin committed suicide a few weeks ago." This statement is a significant red flag indicating a higher risk of suicide. When an adolescent is exposed to suicide, especially within their family or close social circle, they become more vulnerable due to the potential for social contagion. This scenario increases the urgency for intervention and support to prevent a similar outcome.

Choice B rationale:

"He spends much of his time with his two school friends." While changes in social behavior might raise concerns, this statement alone does not directly indicate a risk of suicide. Adolescents can experience shifts in their social preferences for various reasons, and it's not a definitive sign of suicidal ideation or intent.

Choice C rationale:

"He has slept 9 hours each night for the past 2 years." Sleeping patterns alone do not strongly correlate with suicide risk. However, drastic changes in sleep patterns, such as insomnia or hypersomnia, might be indicative of underlying mental health issues. In this case, the consistent sleep pattern mentioned does not directly signal a risk of suicide.

Choice D rationale:

"He is very religious and attends services twice a week." Religious involvement can have protective effects on mental health, and attending religious services can provide a support network. While religion might offer some resilience against suicide, it is not a definitive indicator. Other factors need to be considered in conjunction with religious activities. For , the statement indicating an adolescent's higher risk of suicide is "His cousin committed suicide a few weeks ago" (Choice A). This experience increases the risk due to the potential for social contagion. The other options, including spending time with school friends, sleep patterns, and religious involvement, do not directly suggest an imminent risk of suicide.

A. "How long has this been going on?". B. "It sounds like you're having a difficult time.". C. "Have you talked to your parents about this yet?". D. "Why do you think you are so anxious?".

Correct Answer is B

Explanation

The correct answer is choice B. "It sounds like you're having a difficult time."

Choice A rationale:

"How long has this been going on?" This question focuses on the duration of the client's symptoms, which might not be the most appropriate response at this point. The client's immediate emotional state and distress should be acknowledged before delving into the duration of the issue.

Choice B rationale:

"It sounds like you're having a difficult time." This response demonstrates empathy and understanding towards the client's emotional state. It acknowledges the client's feelings without making assumptions or probing for specific details. It provides a supportive environment for the client to open up further.

Choice C rationale:

"Have you talked to your parents about this yet?" This question assumes that the client's parents are a source of support and that the client has not yet spoken to them about their feelings. It also directs the conversation towards external parties instead of focusing on the client's immediate emotions.

Choice D rationale:

"Why do you think you are so anxious?" This question might come across as confrontational or demanding, potentially making the client defensive. It could hinder open communication and create a barrier between the nurse and the client.
