Critical Care Registered Nurse (CCRN) Practice Exam

The primary purpose of a craniotomy is to provide access for various brain treatments. This surgical procedure allows neurosurgeons to access different regions of the brain for a range of interventions, including the removal of tumors, draining abscesses, repairing damaged vessels, and treating conditions like hematomas or traumatic brain injuries.

While removal of brain tumors and repair of skull fractures may occur during a craniotomy, these are specific indications and not the defining purpose of the procedure. Similarly, inserting a shunt is a targeted intervention that might be performed as part of a craniotomy but does not encompass the full scope of its purpose. The versatility of the craniotomy in addressing multiple types of neurological issues is what makes option B the most accurate choice regarding its primary purpose.
