Rationale: Diazepam, a CNS depressant, can interact with Fentanyl causing severe sedation when administered concurrently. This is due to the additive central nervous system depressant effects of both medications, which can lead to excessive sedation, respiratory depression, and other serious adverse effects. Therefore, healthcare professionals need to monitor clients closely for signs of excessive sedation or respiratory depression when administering these medications together.

Rationale: The correct instruction for a client taking Metoprolol, a medication used to treat hypertension, is to avoid sudden changes in position.

Correct Answer: A

Rationale: The correct action when assessing a client receiving Filgrastim for chronic Neutropenia is to assess for bone pain. Bone pain is a known dose-related adverse effect of Filgrastim. Acetaminophen or opioid analgesics can be used to manage bone pain if necessary. Assessing for other types of pain, lung crackles, or heart murmurs would not be specific to the adverse effects of Filgrastim.
