Which type of treatment may involve the use of nerve blocks?

The option involving interventional pain management techniques is described correctly as it encompasses a range of procedures that directly target pain pathways to provide relief. Nerve blocks, which involve the injection of anesthetics or steroids near specific nerves, are a common method used in this type of treatment. They can help interrupt pain transmission and provide significant relief for patients experiencing chronic pain conditions, thereby improving their quality of life.

Other options, while related to healthcare, do not typically involve treatments like nerve blocks. Psychological counseling focuses on the emotional and psychological aspects of pain rather than physical interventions. Primary care assessments are more about evaluating a patient's overall health status and managing common medical issues without delving into specialized pain management techniques. General health screenings involve evaluations to detect potential health issues early but do not provide treatment for pain specifically. Thus, interventional pain management techniques stand out as the appropriate context for the use of nerve blocks.
