The nurse knows which congenital cardiac defect is characterized by a mixing of well-oxygenated blood with poorly oxygenated blood.

A. Reprimand the client about the potential damage that has occurred due to overexercising her body: Reprimanding is likely to increase feelings of guilt and shame, which can exacerbate the disorder. A supportive and empathetic approach is more beneficial.
B. Praise the client for looking at herself in a mirror: This could reinforce a negative preoccupation with body image, which is a significant aspect of anorexia nervosa. Encouraging healthy coping mechanisms is more appropriate.
C. Restrict the client from being weighed: While it is important to manage weight monitoring carefully, outright restriction without addressing the underlying issues can increase anxiety and resistance to treatment.
D. Ask the client to agree to talk to a nurse whenever she feels the urge to exercise: This helps the client develop healthier coping strategies and provides support in managing the urge to overexercise, promoting therapeutic engagement.

A. Ensuring that the client takes care of their ADLS to prevent dependence: While promoting independence is important, ensuring safety is a higher priority to prevent immediate harm.
B. Ensuring that the client environment is safe to prevent injury: Safety is the top priority for clients with Alzheimer's due to their increased risk of falls, wandering, and other accidents. A safe environment helps prevent injuries.
C. Ensuring that the client receives food they like to prevent anxiety: Although providing familiar and preferred foods can reduce anxiety, it is not as critical as ensuring a safe environment.
D. Ensuring that the client meets the other patients to prevent social isolation: Social interaction is beneficial, but ensuring safety takes precedence to prevent potential harm.
