A patient with a history of a spinal cord injury reports a persistent burning pain below the level of the injury. How should the nurse classify this type of pain?

1. A

   Nociceptive somatic pain

2. B

   Nociceptive visceral pain

3. C

   Neuropathic centrally generated pain

4. D

   Neuropathic peripherally generated pain

Explanation

Listen in Hindi

• Neuropathic centrally generated pain is caused by a lesion or disease of the central somatosensory nervous system.
• A spinal cord injury is a lesion of the central nervous system (CNS).
• The patient's report of 'burning' pain is a characteristic descriptor for neuropathic pain.
• Therefore, pain resulting from a spinal cord injury is classified as centrally generated neuropathic pain.

Why Other Options Were Wrong

• Option A: Nociceptive somatic pain arises from injury to tissues like skin, muscle, or bone, not from nerve damage. The patient's pain originates from the spinal cord, which is part of the nervous system.
• Option B: Nociceptive visceral pain originates from internal organs. The patient's injury is to the spinal cord, not an organ like the stomach or pancreas.
• Option D: Neuropathic peripherally generated pain is due to damage to nerves outside of the brain and spinal cord (peripheral nerves). The patient's injury is to the spinal cord, which is central.

• Visual 2: Flowchart: A decision tree for classifying pain, starting with the question 'Is there nerve damage?' to differentiate between nociceptive and neuropathic pain, followed by 'Is the damage in the CNS or PNS?'.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Classification of pain based on pathophysiology to guide bedside assessment, documentation, and the next nursing action.
• Accurate classification of pain is crucial for effective management. Neuropathic pain often responds poorly to traditional analgesics like NSAIDs and opioids but may be treated with adjuvant medications like anticonvulsants (e.g., gabapentin) or antidepressants (e.g., amitriptyline).
• A nurse's thorough pain assessment, including quality, location, and timing, provides the data needed to classify the pain correctly and advocate for the most appropriate treatment plan.
• What if? If the patient described an 'aching' pain in the muscles above the level of injury from overuse of their arms for mobility, this would be classified as nociceptive somatic pain, even in the presence of a spinal cord injury.

How to Approach the Question

• First, analyze the patient's history. The key information is 'spinal cord injury'. This points to a problem in the Central Nervous System (CNS).
• Next, analyze the description of the pain. The word 'burning' is a classic descriptor for neuropathic pain, which is pain caused by nerve damage.
• Combine these two pieces of information: You have neuropathic pain originating from the CNS.
• Evaluate the options based on this conclusion. 'Neuropathic centrally generated pain' is the only option that fits both criteria.
• Eliminate other options: Nociceptive pain is from tissue damage, not nerve damage. Peripheral neuropathic pain is from nerve damage outside the CNS.

Concept Tested & Keywords

• Concept Tested: Classification of pain based on pathophysiology
• Stem keywords: spinal cord injury, burning pain, classify pain
• Lead-in keywords: How should the nurse classify
• Clinical cues: History of spinal cord injury indicates a Central Nervous System (CNS) lesion.
• Clinical cues: The descriptor 'burning pain' is a classic sign of neuropathic pain.
