Assignment #3-procedure cards (5-7-
2025)|Graded A+
Lumbar puncture (LP) - ANSWER-needle puncture of the spinal cavity to extract spinal fluid for
diagnostic purposes, introduce anesthetic agents into the spinal canal, or remove fluid to allow
other fluids (such as radiopaque substances) to be injected; also called spinal puncture and
spinal tap
Nerve conduction velocity - ANSWER-test that measures the speed at which impulses travel
through a nerve
Cerebrospinal fluid (CSF) - ANSWER-laboratory test to examine a sample of the fluid
surrounding the brain and spinal cord that helps diagnose disorders of the central nervous
system, including viral and bacterial infections, tumors, and hemorrhage
Computed tomography angiography - ANSWER-Radiographic image of the interior of a vessel in
combination with a CT scan to produce high-resolution, three-dimensional images of blood
vessels
Electroencephalography (EEG) - ANSWER-recording the electrical activity of the brain via
electrodes on the scalp
Electromyography (EMG) - ANSWER-recording of electrical signals (action potentials) that occur
in a muscle when it is at rest and during contraction to assess muscular disease or nerve
damage
Echoencephalography - ANSWER-ultrasound technique used to study intracranial structures of
the brain and diagnose conditions that cause a shift in the midline structures of the brain
