Question

To help assist a child with lumbar puncture, what do you apply prior to the procedure?

1) EMLA cream
2) antibiotics
3) painkillers
4) sterile gloves

Answer 1

To assist with a lumbar puncture, EMLA cream is applied to numb the area before inserting the needle into the lumbar region, which is a safe location for the procedure. Antibiotics are used to treat bacterial meningitis, diagnosed by lumbar puncture, but are ineffective against viral meningitis.

Step-by-step explanation:

To assist a child with a lumbar puncture, EMLA cream is often applied to the skin prior to the procedure. This cream is a local anesthetic that helps to numb the area where the needle will be inserted, thus helping to reduce pain and discomfort associated with the procedure. Lumbar punctures are performed in the lumbar area of the vertebral column because this area is a relatively safe location to insert a needle without harming the central nervous system (CNS). In this region, the spinal cord has typically ended, reducing the risk of damage to it. Lumbar punctures are a primary test for conditions like meningitis, wherein a sample of cerebrospinal fluid (CSF) is withdrawn for testing pathogens and for chemical analysis. Antibiotics treatment is crucial for bacterial meningitis, as it targets the bacteria causing the condition. In contrast, viral meningitis does not respond to antibiotics but usually presents with milder symptoms and often requires supportive care.
