A highly intoxicated client was brought to the emergency department after found lying on the sidewalk. On admission, the client is awake with a pulse of 70/min and blood pressure of 160/80 mm Hg. An hour later, the client is lethargic, pulse is 48/min, and blood pressure is 200/80 mm Hg. Which action does the nurse anticipate taking next?

Cushing's triad is related to increased intracranial pressure (ICP). Early signs include change in level of consciousness. Later signs include bradycardia, increased systolic blood pressure with a widening pulse pressure (difference between systolic and diastolic), and slowed irregular (Cheyne-Stokes) respirations. Cushing's triad is a later sign that does not appear until the ICP is increased for some time. It indicates brain stem compression. The skull cannot expand after the fontanels close at age 18 months, so anything taking up more space inside the skull (eg, hematoma, tumor, swelling, etc.) is a concern for causing pressure on the brain tissue/brain stem and potential herniation. In this scenario, hidden head trauma causing an intracranial bleed must be ruled out with diagnostic testing. The client's intoxication could blunt an accurate history or presentation of a head injury. (Option A) Atropine is used to stimulate the sinoatrial node in bradycardia with systemic symptoms. An electrocardiogram (ECG) should be obtained prior to administering atropine. In this client, there is no evidence of a cardiac etiology or systemic symptoms of poor perfusion/circulation from the bradycardia. (Option B) Nifedipine (Procardia) is a calcium channel blocker that is a potent vasodilator. However, all components must be considered in this scenario as to the etiology of the hypertension rather than just treating that sign. Ruling out a cerebral cause of the hypertension is most important. (Option D) The nurse would continue to perform neurologic assessments (including GCS). However, it is more important to obtain appropriate diagnostic tests and initiate treatment for the changing neurologic symptoms than to just monitor and document. In addition, the nurse should be performing these assessments more frequently than hourly in this rapidly changing client. Educational objective: Cushing's triad/reflex indicates increased intercerebral pressure. Classic signs include bradycardia, rising systolic blood pressure, widening pulse pressure, and irregular respirations (such as Cheyne-Stokes).
