A nurse is caring for a client who is seeking treatment for opioid use disorder. Which of the following actions should the nurse take?

A. Monitor the client's sodium levels:
This action is not directly related to the administration of olanzapine. Olanzapine does not typically affect sodium levels directly. Monitoring sodium levels is essential for some other medications or conditions, but it is not a specific consideration for olanzapine administration.

B. Evaluate the client's frequency of panic attacks:
Evaluating the frequency of panic attacks is not directly related to the administration of olanzapine. Olanzapine is an antipsychotic medication used to treat conditions like schizophrenia and bipolar disorder. It is not primarily indicated for the treatment of panic attacks. Monitoring panic attacks would be relevant if the client's primary concern was panic disorder, but it's not the priority in this scenario.

C. Inform the client that application site rash is common:
This information is not relevant to the administration of olanzapine in the form of an intramuscular injection. Application site rash is a concern for topical medications or transdermal patches, not for IM injections. Therefore, informing the client about application site rash is not necessary in this context.

D. Observe the client for 3 hours following the administration of medication:
This is the correct action. Olanzapine extended-release IM injection requires close observation for at least 3 hours after administration. This monitoring period is essential due to the potential risk of post-injection delirium/sedation syndrome, which can occur shortly after the injection. Monitoring allows for the early detection of any adverse reactions, ensuring the client's safety and well-being.

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.
