A nurse is collecting a history from a client who has depression. Which of the following statements by the client should the nurse identify as a protective factor against suicide?

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.

A. Rambling speech
Rambling speech is not a typical finding associated with depression. It may indicate other conditions or issues.

B. Insomnia
Insomnia, or difficulty sleeping, is a common symptom of depression. Many individuals with depression experience trouble falling asleep, staying asleep, or both.

C. Rapid mood swings
Rapid mood swings are not typically associated with depression. Depression often involves persistent low mood rather than rapid fluctuations.

D. Sundowning
Sundowning refers to a state of confusion and restlessness that occurs in the late afternoon and evening, often seen in individuals with dementia. While it can be related to mood disturbances, it's not specific to depression.
