A nurse in an emergency department is caring for a client who had a seizure and became unresponsive after stating she had a sudden, severe headache and vomiting. 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 neurologic disorders should the nurse suspect?
A.
Thrombotic stroke
B.
Transient ischemic atack (TIA)
C.
Embolic stroke
D.
Hemorrhagic stroke
The Correct answer and Explanation is:
The correct answer is D. Hemorrhagic stroke.
Explanation:
In this scenario, the nurse should suspect a hemorrhagic stroke based on the client’s symptoms and vital signs. The key indicators include:
- Sudden Severe Headache: The client reports a sudden and severe headache, often described as a “thunderclap” headache. This is a classic symptom of a hemorrhagic stroke, which occurs when a blood vessel in the brain ruptures, leading to bleeding and increased intracranial pressure.
- Unresponsiveness: The client becomes unresponsive after the headache, suggesting significant neurological impairment, which is common in hemorrhagic strokes. This level of unresponsiveness indicates that the brain is under significant stress from the bleeding.
- Elevated Blood Pressure: The client’s blood pressure reading of 198/110 mm Hg is significantly elevated. Hypertension is a major risk factor for hemorrhagic strokes, as it can lead to the rupture of blood vessels in the brain.
- Fever: The elevated temperature of 38.2° C (100.8° F) may suggest an inflammatory response or infection but can also be associated with acute neurological events.
- Respiratory Rate: The respiration rate of 24/min indicates potential respiratory distress, possibly due to increased intracranial pressure affecting brain function and respiratory control centers.
Other Options Considered:
- Thrombotic Stroke (A): Typically associated with gradual onset symptoms and less severe headache.
- Transient Ischemic Attack (TIA) (B): Usually presents with transient neurological symptoms that resolve within 24 hours, not consistent with the client’s current state.
- Embolic Stroke (C): Often has acute onset but typically presents without a severe headache and is more common in patients with a history of heart disease.
In summary, given the sudden onset of severe headache, unresponsiveness, high blood pressure, and the neurological implications, a hemorrhagic stroke is the most plausible diagnosis in this emergency situation. Immediate intervention is crucial, as hemorrhagic strokes require rapid assessment and treatment to prevent further brain damage.
