A nurse is caring for an adolescent who is experiencing depression. Which of the following findings should the nurse expect? (Select all that apply.)

A. Medication side effects: Certain medications can cause cognitive impairment that mimics dementia, but this condition is often reversible if the medication is adjusted or discontinued.

B. Hypothyroidism: Hypothyroidism can lead to cognitive impairment that may be reversible with appropriate thyroid hormone replacement therapy.

C. Vitamin B12 deficiency: Deficiency in vitamin B12 can cause cognitive deficits that are often reversible with supplementation.

D. Multiple small brain infarcts: This condition, often associated with vascular dementia, usually leads to permanent brain damage and is typically not reversible.

A. Evaluate liver function: Although liver function tests can be important, they are not the immediate priority in anorexia nervosa unless there is a specific indication of liver disease or failure. Liver function abnormalities might occur in advanced cases due to malnutrition, but electrolyte imbalances are more immediately life-threatening.

B. Check for blood glucose levels: Blood glucose levels are important, but severe electrolyte imbalances, such as hypokalemia, pose a more immediate risk and require urgent attention to prevent cardiac and neurological complications.

C. Assess for signs of infection: While important, infection is not typically a primary concern in the initial assessment of someone with anorexia unless there are specific signs or symptoms indicating infection.

D. Monitor for electrolyte alterations: Electrolyte imbalances, such as hypokalemia (low potassium) and hypocalcemia (low calcium), can be life-threatening and are common in individuals with anorexia due to malnutrition, vomiting, or use of laxatives. These imbalances can lead to cardiac arrhythmias and other serious complications, making this the priority.
