A nurse suspects that a client admitted for treatment of bacterial meningitis is experiencing increased Intracranial pressure (ICP). Which of the following assessment findings by the nurse supports this suspicion?
A.
A decrease in the Glasgow Coma Score
B.
Photophobia
C.
Fever
D.
Nuchal rigidity
The Correct Answer and Explanation is:
The correct answer is A. A decrease in the Glasgow Coma Score.
Explanation
Intracranial Pressure (ICP) is the pressure within the cranial cavity, which includes the brain, blood, and cerebrospinal fluid (CSF). Elevated ICP can occur in conditions like bacterial meningitis due to inflammation, swelling, and increased fluid volume in the brain. Monitoring ICP is crucial because increased ICP can lead to severe complications, including brain herniation and decreased cerebral perfusion.
1. Decrease in the Glasgow Coma Score (GCS): A decrease in the Glasgow Coma Score is a key indicator of increased ICP. The GCS is a scale used to assess a patient’s level of consciousness based on eye, verbal, and motor responses. A declining GCS suggests that the patient’s neurological status is deteriorating, which can be due to increased pressure within the cranial cavity. As ICP rises, it can compress the brain and impair consciousness, motor responses, and other neurological functions, leading to a lower GCS score. This finding is critical for early intervention and management of increased ICP.
2. Photophobia: Photophobia, or sensitivity to light, is a common symptom of bacterial meningitis but is not a direct indicator of increased ICP. It results from inflammation of the meninges, which can irritate the nerves responsible for light sensitivity. While photophobia is relevant to the diagnosis of meningitis, it does not specifically point to increased ICP.
3. Fever: Fever is also associated with bacterial meningitis and is a response to the infection. However, fever alone does not indicate increased ICP. It is part of the overall clinical picture but does not directly reflect changes in intracranial pressure.
4. Nuchal Rigidity: Nuchal rigidity, or stiffness of the neck, is another classic sign of meningitis. It results from inflammation of the meninges, causing discomfort and resistance when attempting to flex the neck. Like photophobia and fever, nuchal rigidity is more indicative of meningitis itself rather than increased ICP.
In summary, while photophobia, fever, and nuchal rigidity are important symptoms of bacterial meningitis, a decrease in the Glasgow Coma Score is the most direct assessment finding that suggests increased ICP. Monitoring and responding to changes in GCS are essential for managing and mitigating complications associated with elevated ICP.
