A patient diagnosed with schizophrenia says, "Contagious bacteria are everywhere. When they get in your body, you will be locked up with other Infected people. Which problem is evident?

A. Your child has a chemical imbalance of the brain, which leads to altered thoughts: This is the correct answer. It acknowledges the role of a chemical imbalance in the brain contributing to altered thoughts and hallucinations in the context of schizophrenia.

B. Your child's hallucinations are caused by medication interactions: This explanation is not likely in this context. While medications can have side effects, command hallucinations in schizophrenia are primarily related to the underlying disorder.

C. Your child has too little serotonin in the brain causing delusions and hallucinations: While serotonin is involved in mood regulation, attributing hallucinations solely to low serotonin levels oversimplifies the complex neurobiology of schizophrenia.

D. Your child's abnormal hormonal changes have precipitated auditory hallucinations: Hormonal changes are not considered a primary cause of auditory hallucinations in schizophrenia. The emphasis is on neurobiological and genetic factors influencing brain function.

Individuals with OCD often engage in compulsive behaviors, such as repetitive cleaning, as a way to alleviate or decrease anxiety associated with obsessive thoughts. In the context of OCD, obsessions are intrusive and distressing thoughts, images, or urges that cause significant anxiety, while compulsions are repetitive behaviors or mental acts performed in response to the obsessions.

A. Decrease the time available for interaction with people:

While individuals with OCD may isolate themselves due to their symptoms, the primary motivation for repetitive behaviors like cleaning is to manage anxiety, not necessarily to avoid interaction with others.

B. Prevent aggressive and impulsive behaviors:

OCD compulsions are not typically aimed at preventing aggressive or impulsive behaviors. They are driven by the need to reduce distress related to obsessive thoughts.

C. Decrease anxiety:

This is the correct answer. Compulsive behaviors in OCD are often ritualistic actions performed to reduce the anxiety associated with obsessive thoughts. Cleaning, in this case, is a way for the individual to feel a sense of control and alleviate anxiety.

D. Manipulate others

The primary motive behind OCD compulsions is to manage personal anxiety, not to manipulate others. Individuals with OCD often recognize that their compulsions are excessive or irrational, but they feel driven to perform them to alleviate anxiety.
