A nurse is caring for a client who has been brought into an emergency department of a large hospital. The client's family state that the client "took some kind of drugs." The client is dizzy, has recently vomited, and is experiencing paranoia, yelling, "Stay away from me! You are going to kill me!" The client alternates yelling with mumbling and gesturing. Their eyes are darting back and forth as they are talking to the wall. The nurse should suspect the client has used which of the following substances?

C. Dissociative amnesia is characterized by difficulty remembering important personal information, typically of a traumatic or stressful nature, that is inconsistent with ordinary forgetting. The manifestation of guilt is common in individuals experiencing dissociative amnesia, as they may feel guilty about their inability to recall events or about any actions that occurred during the period of amnesia.

A. Hallucinations involve perceiving sensations that are not present in reality, such as hearing voices or seeing things that others do not. While hallucinations can occur in various psychiatric disorders, they are not a typical manifestation of dissociative amnesia.

B. Delusions are false beliefs that are firmly held despite evidence to the contrary. Like hallucinations, delusions can occur in various psychiatric disorders, but they are not characteristic of dissociative amnesia.

D. Anhedonia refers to a reduced ability to experience pleasure or interest in previously enjoyable activities. It is not directly related to dissociative amnesia.

D. This promotes accountability by involving an identified support person in the client's exercise plan. Sharing the exercise log with a support person creates a sense of responsibility and encouragement for the client to adhere to their exercise regimen. Knowing that someone else will review their progress can motivate the client to stay committed to their goals and maintain consistency in their exercise routine.

A. Setting a specific duration for daily exercise is a good goal-setting strategy. However, it does not inherently provide a mechanism for accountability. The client may not feel as motivated to adhere to the exercise plan consistently.

B. This option involves client engagement and preference, which is important for promoting adherence to an exercise routine. However, it does not directly address accountability.

C. Setting a specific timeframe for daily exercise is another goal-setting strategy, but without mechanisms for accountability, the client may struggle to maintain consistency.
