Final answer:
Repetitive behavior in a client with OCD, such as repeatedly applying and removing makeup, is due to an attempt to reduce anxiety caused by obsessions. This behavior is not typically related to narcissism, fear of staff rejection, or medication side effects, but is a characteristic symptom of OCD.
Step-by-step explanation:
The repetitive behavior observed in a client with Obsessive-Compulsive Disorder (OCD) is typically due to an attempt to reduce anxiety. OCD is characterized by the presence of persistent thoughts (obsessions) and repetitive behaviors (compulsions) that the individual feels driven to perform in response to these obsessions, typically with the intention of preventing some dreaded event or situation. However, these compulsions are not connected in a realistic way with what they are designed to neutralize or prevent, or they are clearly excessive. Repeatedly applying, removing, and reapplying makeup might be an example of a compulsive behavior aimed to manage the anxiety that arises from the obsessive thoughts related to appearance or perceived imperfections.
The other options, such as narcissistic behavior, fear of rejection from staff, and adverse effect of antidepressant medication, do not directly explain the repetitive behaviors that are a hallmark of OCD, as outlined in sources like Abramowitz & Siqueland (2013) and Ruscio et al. (2010). It is important to note that these behaviors are a direct manifestation of the condition itself rather than a reaction to medication or social interactions.
