Within the nurse's scope of practice, which function is exclusive to the advanced practice psychiatric nurse?

A. By using a screening tool such as the CAGE questionnaire: This is the correct answer. The CAGE questionnaire is a widely used tool for screening alcohol use disorders. It consists of four questions that assess whether the individual has concerns or issues related to their alcohol consumption. A positive result may indicate a need for further assessment and intervention.

B. By asking directly if the client has ever had a problem with alcohol: While direct questioning is important, using a structured screening tool provides a more standardized and objective approach. The CAGE questionnaire offers specific questions that help identify potential issues with alcohol use.

C. By holistically assessing the client using the CINA scale: The CINA scale (Checklist of Nonverbal Indicators of Affect) is primarily used to assess nonverbal behaviors related to affect. While it may be useful in certain contexts, it is not specifically designed for assessing alcohol use disorders.

D. By referring the client for physician evaluation: While physician evaluation may be necessary for a comprehensive assessment, using a screening tool such as the CAGE questionnaire is an appropriate initial step. The results of the screening tool can guide further assessment and appropriate referrals.

A. Altered nutrition: less than body requirements R/T hyperactivity AEB weight loss: This is the correct priority nursing diagnosis. The client's significant weight loss is indicative of altered nutrition and poses a more immediate threat to their well-being. Addressing the nutritional deficit takes precedence to ensure the client's physical health and stability.

B. Altered sleep patterns R/T mania AEB insomnia for the past 3 nights: While altered sleep patterns are a concern, the priority in this scenario is the significant weight loss, which is indicative of altered nutrition. Nutritional deficits can have more immediate health consequences.

C. Knowledge deficit R/T bipolar disorder AEB concern about symptoms: While addressing knowledge deficits is important for the client's understanding of their condition, the immediate concern is the client's significant weight loss. Nutritional deficits can lead to serious health issues and should be addressed as a priority.

D. Risk for suicide R/T powerlessness AEB insomnia and anorexia: While the client's symptoms may contribute to a risk for suicide, the immediate focus should be on addressing the altered nutrition, which is a more direct threat to the client's physical health.
