A 50-year-old man is scheduled for a lumbar puncture. Which of the following statements made by the patient indicates that he understands the procedure?

"Fluid will be removed from my spinal canal."
"I must lie flat after the procedure for at least four hours."


• Lumbar puncture involves the insertion of a needle into the subarachnoid space and the removal of cerebrospinal fluid for diagnostic or therapeutic purposes

• To prevent injury, the patient must not move during the insertion of the needle into the spinal canal. The patient will need to lie on his/her side, curling forward so that the knees are flexed toward the chest with the chin touching the knees

• After the procedure the patient will have to lie flat for 4-8 hours depending on physician, hospital protocol, or if the patient has continued signs of a headache

• Electrical activity associated with innervations of skeletal muscle is measured through electromyography. Electroencephalography involves studying brain waves, not lumbar puncture

• Lumbar puncture does not use dyes to inject into the body
