Free CNRN Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

Children with Down syndrome are at increased risk for atlantoaxial instability due to ligamentous laxity, which can lead to cervical spinal cord compression. This requires activity precautions. Multiple sclerosis and Parkinson disease are unrelated. Brain aneurysm rupture is not specifically associated with Down syndrome in pediatric populations. Screening for cervical instability is important before sports participation.

Comprehensive and Detailed Explanation:

Morning vomiting and irritability in children are classic signs of increased intracranial pressure due to brain tumor growth. Symptoms often worsen after lying down overnight. Increased appetite, urination, and mild cough are unrelated to intracranial pathology. Early detection of ICP signs is critical to prevent neurological deterioration and herniation.

Comprehensive and Detailed Explanation:

By 15 months, most children are able to walk independently or at least cruise along furniture. Failure to achieve this milestone suggests possible motor developmental delay or neuromuscular disorder. Smiling, tantrums, and sleeping patterns are normal developmental behaviors. Early evaluation is important for timely intervention and improved outcomes.

Comprehensive and Detailed Explanation:

Trigeminal neuralgia is a neuropathic pain disorder affecting cranial nerve V, characterized by sudden, severe, electric shock-like facial pain triggered by light touch, chewing, or speaking. It is episodic and can be debilitating. Progressive limb weakness and fever suggest other neurological or infectious conditions. Vision loss is unrelated to trigeminal nerve pathology.

Comprehensive and Detailed Explanation:

Patients with elevated intracranial pressure require a calm, low-stimulation environment to reduce cerebral metabolic demand and prevent further increases in ICP. Clustering care minimizes interruptions and avoids repeated spikes in pressure. Frequent suctioning and unnecessary stimulation can significantly raise ICP due to coughing and sympathetic responses. Trendelenburg position increases venous pressure and worsens ICP. Head rotation impairs venous drainage from the brain and should be avoided.
