When teaching the parents of a child with attention deficit hyperactivity disorder (ADHD), which statement by the parents would indicate the need for further teaching?

The stages of aggressive incidents (often based on the Assault Cycle) describe the progression of a client's behavior from a baseline state to a loss of control. Identifying these phases is critical for the psychiatric nurse because the goal shifts from de-escalation to safety management as the client moves through the cycle.

Rationale:

A. During the escalation phase, the client’s responses represent a move toward a loss of control. Symptoms include rapid breathing, loud voice, and agitation. Although more difficult than the triggering phase, intervention (such as offering PRN medication or a quiet area) is still frequently effective in preventing physical violence.

B. The post-crisis phase occurs after the incident has ended. The client may experience fatigue, guilt, or remorse. Intervention here is vital for reconciliation and debriefing, but it is not focused on preventing the aggression, as the aggressive act has already occurred.

C. In the crisis phase, the client is in a state of total loss of control and is physically aggressive. At this point, verbal de-escalation and behavioral interventions are least likely to be effective because the client's cognitive processing is overwhelmed by high emotional arousal. The nurse's priority shifts from prevention to safety interventions, such as seclusion or restraint.

D. The triggering phase is the point where an event or circumstance initiates a stress response. At this early stage, the client is most receptive to therapeutic communication and problem-solving. This is the stage where intervention is most effective at preventing the cycle from advancing.

Anorexia nervosa is characterized by a persistent restriction of energy intake leading to significantly low body weight, an intense fear of gaining weight, and a distorted perception of body shape or size. A hallmark of the disorder is anosognosia, the physiological lack of insight into the illness, which explains why the client may insist "nothing is wrong" despite being in a state of physical starvation.

Rationale:

A. Clients with anorexia nervosa typically have a very low self-concept that is inextricably tied to their weight and body shape. Their sense of self-worth is often fragile and dependent on their perceived success at restricting food intake, rather than a genuine positive self-image.

B. Episodes of overeating followed by weight gain are more characteristic of Binge Eating Disorder. Although those with the binge-purge subtype of anorexia may have episodes of overeating, the defining feature of anorexia nervosa remains the significantly low body weight, which distinguishes it from Bulimia Nervosa, where the client is often at a normal or near-normal weight.

C. Severe weight loss resulting from self-imposed starvation is the primary clinical indicator. Even when emaciated, the client may view themselves as overweight. The nurse must look for physical cues such as lanugo (fine hair growth), bradycardia, and amenorrhea, as the client will likely minimize or deny the severity of their dieting habits.

D. This disorder is characterized by cognitive rigidity and perfectionism, rather than flexibility. Clients often adhere to strict, ritualistic eating patterns and food rules. Spontaneity is usually avoided because it represents a loss of control over their environment and caloric intake.
