A nurse is teaching participants at a community center about advance directives. Which of the following information should the nurse include in the teaching?

Rationale:

A. Self-mutilation: This behavior is more commonly associated with borderline personality disorder. Individuals with borderline traits may engage in self-harm as a means of emotional regulation or response to abandonment fears, not typical in antisocial personality disorder.

B. Social isolation: Clients with antisocial personality disorder are often socially manipulative and may actively engage with others for personal gain. They are typically not socially withdrawn but can be superficially charming and exploitative.

C. Paranoid ideation: Paranoia is more closely linked with paranoid or schizotypal personality disorders. While someone with antisocial traits may be suspicious if it serves their manipulative purposes, persistent paranoid ideation is not a defining feature.

D. Lack of empathy: A hallmark feature of antisocial personality disorder is a disregard for others' feelings, rights, and safety. These clients often exhibit a lack of remorse and empathy, making them prone to violating social norms and laws without guilt.

Rationale:

• Parotid glands: Parotid gland enlargement is a typical finding in clients with bulimia nervosa due to repeated episodes of self-induced vomiting. The recurrent stimulation of salivary glands leads to painless swelling, often bilateral, and may also contribute to facial puffiness or a rounded appearance.
• Potassium level: A potassium level of 3.0 mEq/L is low and may result from either bulimia nervosa or anorexia nervosa. In bulimia, this is typically due to purging through vomiting or laxative use; in anorexia, it stems from prolonged restriction, dehydration, and possible diuretic misuse. Both conditions increase the risk of cardiac complications.
• Weight: The client’s weight of 61.8 kg with a BMI of 20.7 falls within the normal range and is more consistent with bulimia nervosa. Individuals with anorexia nervosa usually present with a significantly lower body weight and BMI, typically below 18.5, due to extreme caloric restriction and prolonged starvation.
• Sodium level: A sodium level of 134 mEq/L is slightly low and can occur in both bulimia nervosa and anorexia nervosa. In bulimia, frequent vomiting may cause sodium loss, while in anorexia, hyponatremia can develop from malnutrition, dehydration, or excessive water intake in attempts to suppress appetite or manipulate weight.
• Hand findings: Calluses on the index and middle fingers, known as Russell’s sign, are associated with bulimia nervosa. These result from repeated trauma during induced vomiting episodes, as the hand comes into contact with the teeth. This finding is a classic physical sign of chronic purging behavior.
