- A. The client verbalizes knowledge of a maintenance diet.
- B. The client demonstrates assertiveness with family.
- C. The client verbalizes her body size accurately.
- D. The client demonstrates control of obsessive behaviors.
Correct Answer: C
Rationale: Part of the problem for anorexic clients is an altered view of their body appearance (visualizing themselves as fat even when they are emaciated). Knowledge of a maintenance diet involves a knowledge deficit. Assertiveness with family involves possible resolution of family-dynamic issues. Control of obsessive behaviors involves psychological adaptation.
Which of the following individuals may legally give informed consent?

- D. a 6-month-old baby needing bowel surgery
Correct Answer: C
Rationale: Only competent adults can legally give informed consent. The 72-year-old female is presumed competent unless stated otherwise. An individual with advanced Alzheimer's lacks decision-making capacity, a non-emancipated minor cannot consent, and infants are legally incapable of consenting; their guardians must provide consent.
