A client diagnosed with anorexia nervosa is newly admitted to an inpatient psychiatric unit. Which nursing intervention takes priority?

Choice A reason: Assessing family health history may provide context for genetic predispositions to mental health disorders. However, it is not the priority upon admission, as it does not address immediate physiological risks like malnutrition or cardiac instability, which are critical in anorexia nervosa due to severe weight loss. Choice B reason: Assessing the client’s knowledge of treatment options is important for engaging them in their care plan. However, this is secondary to addressing immediate physical health risks, such as electrolyte imbalances or cardiac complications, which are life-threatening in anorexia nervosa and require urgent attention. Choice C reason: Assessing early disturbances in family interactions may help identify triggers for anorexia nervosa, such as emotional stress. However, this is not the priority upon admission, as it does not address the immediate physiological dangers of malnutrition, dehydration, or organ dysfunction, which take precedence. Choice D reason: Anorexia nervosa can cause severe physiological complications, including bradycardia, hypotension, and electrolyte imbalances, due to malnutrition. Assessing and monitoring vital signs and lab values is critical to identify life-threatening conditions like hypokalemia or cardiac arrhythmias, ensuring immediate stabilization and guiding treatment, making it the priority intervention.
