Final answer:
The patient's intention to drive home and go to bed after a head injury requires immediate nurse intervention due to the potential risk of cognitive impairment and the need for monitoring any progression of neurological symptoms.
Step-by-step explanation:
The statement by a patient being discharged from the emergency department (ED) after a head injury that indicates a need for intervention by the nurse is: "I am going to drive home and go to bed." This raises concerns as patients with head injuries may have cognitive impairments or delayed symptoms that can impair driving ability and put them at risk. Additionally, after a head injury, it's crucial to have someone monitor the patient's condition, as sleep can complicate the assessment of evolving neurological signs and a decrease in consciousness.
