A 44-year-old patient presents to the emergency department with a closed head injury after a motor vehicle collision. The patient is showing signs of decorticate posturing and has a Glasgow Coma Scale (GCS) score of 8. Neuroimaging has revealed a subdural hematoma. Which of the following interventions should the nurse prioritize to manage the patient's increased intracranial pressure?
Elevate the head of the bed to 30 degrees while maintaining cervical spine precautions if indicated.
Immediately administer osmotic diuretics to reduce cerebral edema.
Provide a quiet environment to minimize sensory stimulation and reduce cerebral metabolic demand.
Administer a stool softener to prevent straining during bowel movements, which can increase ICP.
