What possible conditions were ruled out by the surface examination, normal body temperature and CBC?
And Explain the process and purpose of a lumbar puncture or “spinal tap”.

Hello!

Possible conditions ruled out by the surface examination, normal body temp. and cbc are schizophrenia, meningitis, hypothermia, and hyperthermia. A lumbar puncture (LP), also called a spinal tap, is an invasive outpatient procedure used to remove a sample of cerebrospinal fluid (CSF) from the subarachnoid space in the spine. (This test is similar to a blood test, in which a needle is inserted into an artery to collect blood for testing.)
