A school nurse notices a sudden drop in grades and increased absenteeism in a previously high-achieving student.
When approached, the student avoids eye contact and has flat affect. What is the nurse's next best action?

Choice A rationale

Excessive dental caries and enlarged tonsils are more commonly associated with bulimia nervosa due to the erosive effects of recurrent vomiting on tooth enamel and compensatory hypertrophy of lymphoid tissue in the pharynx. While indicative of disordered eating, they are not primary physical markers for anorexia nervosa.

Choice B rationale

A skeletal appearance with lanugo on arms is highly indicative of anorexia nervosa. The emaciation results from severe caloric restriction, leading to significant adipose tissue and muscle loss. Lanugo, fine downy hair, develops as a compensatory mechanism to conserve body heat due to the lack of insulating fat.

Choice C rationale

An irregular heart rate, such as bradycardia, is a common finding in anorexia nervosa due to metabolic slowdown and electrolyte imbalances. However, heavy menstruation (menorrhagia) is not typically associated with anorexia; amenorrhea (absence of menstruation) is a classic sign due to hormonal suppression from malnutrition.

Choice D rationale

Being overweight with a puffy face is inconsistent with the diagnostic criteria for anorexia nervosa, which is characterized by significantly low body weight. A puffy face might suggest fluid retention or salivary gland enlargement, which can occur in bulimia, but not typical for anorexia.

Choice A rationale

Offering privacy and allowing gradual self-expression respects the adolescent's developmental stage, which often includes a need for autonomy and fear of judgment. Providing a non-threatening environment can reduce anxiety and build trust, fostering a sense of security that encourages the patient to open up when they feel ready, without feeling pressured or overwhelmed.

Choice B rationale

Encouraging immediate discussion with parents might be premature and perceived as a lack of understanding by the adolescent. Adolescents often value peer relationships and may find it difficult to express sensitive emotions to parents, especially after a traumatic event like an injury. This approach could increase their withdrawal and reluctance to communicate.

Choice C rationale

Focusing solely on physical care neglects the psychological and emotional needs of the adolescent, which are crucial for holistic recovery. Emotional distress can hinder physical healing and overall well-being. Avoiding emotional support can make the patient feel invalidated and isolated, potentially prolonging their withdrawal and emotional distress.

Choice D rationale

Assigning a withdrawn adolescent to a shared room without prior assessment or consent can exacerbate their anxiety and discomfort. While socialization is important, forcing it upon a patient who is already withdrawn can be counterproductive, potentially leading to increased stress and a further retreat into themselves rather than improving their social engagement.
