A nurse in the emergency department is caring for a client who had a seizure and became unresponsive after stating they had a sudden, severe headache. The client’s vital signs are as follows: blood pressure of 198/110 mm Hg, pulse of 82/min, respirations of 24/min, and a temperature of 38.2° C (100.8° F). Which of the following neurological disorders should the nurse suspect?
A.
Embolic stroke
B.
Thrombotic stroke
C.
Transient ischemic attack (TIA)
D.
Hemorrhagic stroke
The Correct answer and Explanation is:
The correct answer is D. Hemorrhagic stroke.
In this scenario, the client presents with a sudden, severe headache, which is often described as a “thunderclap” headache or the worst headache of their life. This type of headache is highly suggestive of a hemorrhagic stroke, particularly a subarachnoid hemorrhage. The sudden onset of a severe headache, combined with the patient’s unresponsiveness, points towards a serious neurological event.
The vital signs further support this suspicion. The patient’s blood pressure of 198/110 mm Hg indicates severe hypertension, which can be a precipitating factor for hemorrhagic strokes. The elevated blood pressure might result from the body’s response to increased intracranial pressure (ICP) or as part of a stroke’s physiological changes. Additionally, the elevated respiratory rate (24/min) and temperature (38.2° C) suggest a possible stress response or infection, further complicating the clinical picture.
While both embolic and thrombotic strokes can cause headaches and neurological deficits, they typically present differently. Embolic strokes often result in sudden-onset focal neurological deficits without the severe headache, whereas thrombotic strokes are generally associated with gradual onset symptoms rather than an abrupt headache. A transient ischemic attack (TIA) usually resolves within 24 hours and does not lead to the prolonged unresponsiveness observed in this case.
In summary, considering the acute presentation of severe headache, unresponsiveness, and significant hypertension, a hemorrhagic stroke is the most plausible diagnosis. Immediate imaging studies, such as a CT scan, would be necessary to confirm the presence of a hemorrhage and guide further management. Early recognition and treatment are crucial in optimizing outcomes for the patient.
