A 36 year old female complains of headache and neck pain. Examination by a nurse reveals painful flexion of the neck of the chest (nuchal rigidity). This could be due to?

Appeared in: BHU NO - 2015

Explanation

Meningitis is the inflammation of the meninges, the membranes surrounding the brain and spinal cord.
This inflammation irritates the nerve roots in the cervical spine and leads to a reflexive spasm of the neck muscles, causing the classic sign of nuchal rigidity (stiff neck).
The combination of headache, neck pain, and nuchal rigidity is a hallmark presentation of meningitis.
Fever is also a very common accompanying symptom, though not mentioned in this specific stem.

Option A: Brain tumors typically cause symptoms that progress gradually over weeks to months. Common signs include persistent headaches that are worse in the morning, seizures, and focal neurological deficits (like weakness or vision changes) related to the tumor's location. Nuchal rigidity is not a primary sign.
Option C: A cerebro-vascular accident (CVA), or stroke, presents with the sudden onset of focal neurological deficits, such as one-sided weakness, facial droop, or speech difficulties. Nuchal rigidity is not a typical sign of the most common types of stroke (ischemic or intracerebral hemorrhage).
Option D: A sub-dural hematoma, a collection of blood under the dura mater, typically results from head trauma. Symptoms can be acute or chronic and often include headache, confusion, and changes in consciousness. Nuchal rigidity is an uncommon finding.

Clinical Relevance

Nursing practice connection: Use the key finding related to Differential diagnosis of nuchal rigidity to guide bedside assessment, documentation, and the next nursing action.
Recognizing nuchal rigidity as a potential sign of meningitis is a critical nursing skill. Bacterial meningitis is a medical emergency requiring prompt diagnosis and antibiotic treatment to prevent severe neurological complications or death.
Nurses must act quickly to implement droplet precautions for suspected bacterial meningitis even before a definitive diagnosis is made, to protect other patients and healthcare workers.
What if? If the patient also presented with a petechial or purpuric rash, the suspicion for meningococcal meningitis would be extremely high, signaling a life-threatening emergency (meningococcemia) that requires immediate intervention.

How to Approach the Question

First, identify the key clinical finding in the question stem. Here, it is 'painful flexion of the neck of the chest (nuchal rigidity)'.
Associate this key sign with its underlying pathophysiology. Nuchal rigidity is a direct indicator of meningeal irritation.
Evaluate the given options based on this pathophysiology. Ask yourself, 'Which of these conditions directly causes inflammation or irritation of the meninges?'
Meningitis is, by definition, inflammation of the meninges, making it the most direct and likely cause.
Consider why the other options are less likely. Brain tumors, strokes, and hematomas do not typically present with nuchal rigidity as a primary sign, although it can occur as a secondary complication in some specific circumstances.
