A nurse is collecting data from a client who is taking lithium. Which of the following findings should the nurse identify as early manifestations of lithium toxicity? (Select all that apply.)

A. Unlike anorexia nervosa, where individuals typically appear underweight, people with bulimia nervosa often maintain a body weight within the normal or even overweight range. This can make it challenging to identify based on physical appearance alone, as individuals may hide their binge-eating and purging behaviors.
B. Individuals with bulimia nervosa often engage in episodes of binge-eating, during which they consume large amounts of food in a short period and feel a loss of control over their eating. This is followed by compensatory behaviors such as self-induced vomiting, misuse of laxatives or diuretics, fasting, or excessive exercise to prevent weight gain.
C. Bulimia nervosa does not directly increase the risk of developing diabetes mellitus. However, the binge-eating episodes characteristic of bulimia can lead to metabolic disturbances and insulin resistance over time. This can potentially increase the risk of developing type 2 diabetes in individuals who are predisposed or have other risk factors.
D. While self-induced vomiting is a common purging method in bulimia nervosa, there are other ways individuals may attempt to compensate for binge-eating episodes, such as excessive exercise, fasting, or misuse of laxatives or diuretics. The key diagnostic criteria for bulimia nervosa include recurrent episodes of binge-eating and inappropriate compensatory behaviors to prevent weight gain.

A. Adolescents who are preparing to leave home for college are generally more independent and have a higher level of verbal communication compared to younger children. They are less likely to be at high risk for physical abuse because they can potentially seek help or report abuse more readily.

B. School-age children typically have better verbal communication skills and may express their desires and feelings more clearly compared to younger children. They are generally less vulnerable to physical abuse compared to younger children who may not be able to communicate their experiences as effectively.
C. Preschoolers are at a higher risk for physical abuse compared to older children and adolescents. They are still developing verbal communication skills and may not be able to express their feelings or report abuse clearly. Their dependence on caregivers for basic needs and care also increases their vulnerability.
D. Toddlers, especially those with chronic health conditions like cystic fibrosis, are particularly vulnerable to physical abuse. Their young age, dependency on caregivers for basic needs, limited verbal communication skills, and potential health challenges increase their risk. Caregivers may feel overwhelmed or stressed by the child's condition, which could potentially contribute to abusive behaviors.
