Final answer:
The correct matches for the medical tests and their uses are: Cerebral angiography requires contrast dye, CT scans and MRI provide precise imaging, Ventriculostomy reduces ICP, and a lumbar puncture assesses for infection and bleeding. A lumbar puncture is performed in the lower lumbar area due to safety considerations in the anatomy of the CNS and is critical for diagnosing infections like meningitis.
Step-by-step explanation:
The student has asked for assistance in matching medical tests with their uses.
The correct matches are:
Cerebral angiography (1) requires contrast dye, CT Scan and MRI (2) provide precise images needed, Ventriculostomy (3) is a procedure to reduce Intracranial Pressure (ICP), while (4) a CT scan is generally a quick, accurate and painless procedure, and a lumbar puncture (5) is used to assess for infection and bleeding by analyzing cerebrospinal fluid (CSF).
A lumbar puncture is a medical procedure used to obtain a sample of CSF. This test is crucial for diagnosing conditions such as meningitis. It is performed in the lower lumbar area of the vertebral column because this is a relatively safe location to insert a needle due to the anatomy of the Central Nervous System (CNS).
Furthermore, the lumbar puncture can help identify if a cerebrospinal infection is present, as in the case of a patient with symptoms that suggest an infection may have spread to the nervous system.
