Which fluid is aspirated or collected in the following procedure?
Appeared in: AIIMS Delhi NO - 2018
Explanation
- The image clearly depicts a lumbar puncture (spinal tap), a procedure performed in the lower back.
- During a lumbar puncture, a needle is inserted into the subarachnoid space, which is filled with cerebrospinal fluid (CSF).
- Therefore, cerebrospinal fluid is the substance aspirated during this procedure.
- CSF analysis is essential for diagnosing various neurological disorders, including infections, hemorrhages, and inflammatory diseases.
Why Other Options Were Wrong
- Option A: Pericardial fluid is located in the pericardial sac surrounding the heart, not in the spinal column.
- Option B: Synovial fluid is a lubricant found in the cavities of synovial joints, such as the knee or shoulder.
- Option D: Vitreous fluid (or vitreous humor) is the gel-like substance that fills the eyeball behind the lens.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of the fluid collected during a lumbar puncture procedure as background academic context rather than a clinical decision trigger.
- A key nursing responsibility is to correctly position the patient for a lumbar puncture to ensure the provider can access the subarachnoid space safely and effectively.
- Post-procedure monitoring is critical. Nurses must assess for complications, the most common being a post-lumbar puncture headache, which is caused by CSF leakage and is typically worse when upright.
- What if? If the collected CSF appeared cloudy or purulent instead of clear, the nurse should anticipate a diagnosis of bacterial meningitis and prepare for the administration of urgent intravenous antibiotics as per protocol.
How to Approach the Question
- First, carefully analyze the image provided. Identify the anatomical location (lower back/lumbar spine) and the action being performed (insertion of a needle).
- Recognize the procedure as a lumbar puncture or spinal tap based on these visual cues.
- Recall or deduce the purpose of a lumbar puncture, which is to access the space surrounding the spinal cord.
- Consider the fluids listed in the options and their locations in the body.
- Match the procedure (lumbar puncture) with the correct fluid (cerebrospinal fluid), which is found in the central nervous system.
- Eliminate the other options by identifying the correct procedures for their collection (pericardiocentesis for pericardial fluid, arthrocentesis for synovial fluid).
Concept Tested & Keywords
- Concept Tested: Identification of the fluid collected during a lumbar puncture procedure.
- Stem keywords: fluid, aspirated, collected, procedure
- Lead-in keywords: Which
- Clinical cues: The image shows a needle inserted into the lumbar region of the spine, which is the key visual cue for identifying the procedure as a lumbar puncture.
