A nurse is assessing a client who experienced a sexual assault. Which of the following findings should the nurse identify as an indication the client might be experiencing posttraumatic stress disorder?

A. Encourage the client to join group activities:
Encouraging a client experiencing a manic episode to join group activities is not the best option. Manic episodes are characterized by heightened energy, impulsive behavior, and decreased attention span. Group activities may overstimulate the client, making it difficult for them to focus or participate appropriately. It's essential to minimize stimulation and provide a calm environment to help manage the symptoms of mania.

B. Administer methylphenidate to the client:
Methylphenidate is a stimulant commonly used to treat attention deficit hyperactivity disorder (ADHD). Administering a stimulant like methylphenidate to a person in a manic state can exacerbate their symptoms. It would increase their already elevated energy levels, restlessness, and impulsivity, making the manic episode more intense and challenging to manage. Using stimulant medications in this context is contraindicated.

C. Dim the lights in the client's room:
Dimming the lights in the client's room is the appropriate choice. Bright lights can increase agitation and restlessness in individuals experiencing a manic episode. Dimming the lights creates a calming environment, reducing excessive stimulation and promoting relaxation. A calm atmosphere is crucial for someone going through a manic episode to help them manage their symptoms effectively.

D. Provide detailed explanations to the client:
During a manic episode, individuals often have racing thoughts and may have difficulty concentrating. Providing detailed explanations can overwhelm the client, as they might have trouble processing complex information in this state. Instead, simple and clear communication is more effective. It's important to provide straightforward instructions and information to prevent further agitation and confusion.

A. "Since injuring my knee, I've decided to become the team manager."
Option A represents an adaptive use of the ego defense mechanism known as sublimation. Sublimation is a process in which a person channels potentially negative or harmful impulses or feelings into more socially acceptable and constructive activities. In this case, the adolescent with the injured knee is using the opportunity to become the team manager, which is a positive and constructive way to stay engaged with the team despite the setback of the injury.

B. "Since my mom died, I focus all my attention on my grades."
This is an example of reaction formation, a defense mechanism where someone overemphasizes the opposite of their true feelings. In this case, the individual might be hiding or avoiding their grief by focusing on grades.

C. "I didn't tell the teacher about the bullying because it wouldn't have changed anything."
This is an example of rationalization, where the individual provides a logical-sounding but potentially inaccurate explanation for their actions. It can be a defense mechanism to justify or make more acceptable one's choices.

D. "I'm not even going to think about writing that thesis paper until after prom."
This is an example of procrastination or avoidance, which is not an ego defense mechanism but a coping or time-management strategy. It doesn't represent an adaptive use of a defense mechanism in this context.
