Free CNRN Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

Bacterial meningitis typically produces cerebrospinal fluid with elevated protein, decreased glucose due to bacterial metabolism, and a predominance of neutrophils. These findings help distinguish bacterial meningitis from viral meningitis, which more commonly demonstrates lymphocytic predominance and normal glucose levels. Recognition of CSF patterns assists nurses in anticipating treatment priorities and monitoring disease progression.

Comprehensive and Detailed Explanation:

Sudden facial droop, arm weakness, and speech difficulty are classic signs of acute stroke. Immediate activation of stroke protocol is critical to ensure rapid imaging, diagnosis, andpotential reperfusion therapy. Time is brain, and delays reduce the chance of tissue salvage. Swallowing assessment is important later but not before stabilization and imaging. Oral glucose is only indicated if hypoglycemia is confirmed. Oral hydration is contraindicated until swallowing safety is established.

Comprehensive and Detailed Explanation:

Bacterial meningitis presents with fever, severe headache, neck stiffness, and photophobia due to meningeal inflammation. It is a life-threatening infection requiring immediate antibiotic therapy. Mild dizziness, chronic fatigue, and muscle cramps are nonspecific and not indicative of acute CNS infection.

Comprehensive and Detailed Explanation:

Brain abscesses often arise from contiguous infections such as chronic sinusitis, otitis media, or dental infections. They may also occur via hematogenous spread in immunocompromised patients. Chronic sinus infections provide a direct pathway for bacterial invasion into the CNS. Migraine, hypertension, and allergies do not increase risk for brain abscess formation.

Comprehensive and Detailed Explanation:

Cerebellar tumors affect coordination, balance, and motor control, leading to ataxia, unsteady gait, dysmetria, and difficulty with fine motor tasks. These symptoms reflect cerebellar dysfunction. Aphasia is related to cortical damage, memory loss is typically cortical or degenerative, and facial rash is unrelated to neurological tumor pathology.
