Final answer:
The nurse should report the abnormal findings of the blood pressure (BP) and intracranial pressure (ICP) to the health care provider first. Immediate medical intervention may be necessary for a patient with a diffuse axonal injury.
Step-by-step explanation:
The nurse should take action b. Report the BP and ICP to the health care provider first. A systemic blood pressure (BP) of 106/52 mm Hg and an intracranial pressure (ICP) of 14 mm Hg are both abnormal readings for a patient with a diffuse axonal injury. These readings indicate the need for immediate medical intervention to ensure the patient's safety and well-being. By reporting the BP and ICP to the health care provider, the nurse can facilitate appropriate interventions and further assessment of the patient's condition.
