Chapter 13, Problem 8ILQ
Watch this video (http://openstaxcollege.org/l/lumbarpuncture) that describes the procedure known as the lumbar puncture, a medical procedure used to sample the CSF. Because of the anatomy of the CNS, it is a relative safe location to insert a needle. Why is the lumbar puncture performed in the lower lumbar area of the vertebral column?

Where along the vertebral column is a needle inserted for a lumbar puncture? Which landmark can you use to find this level?
PLEASE provide citations in APA style.
When removing cerebrospinal fluid during a spinal tap, the needle is inserted below L2. Explain why spinal taps are not done above this level.
During a lumbar puncture (spinal tap), blood is discovered in thepatient’s CSF. What does this finding suggest?

- True and falsearrow_forwardDuring a procedure called a lumbar puncture,CSFsurrounding the meringues is withdrawn with a needle. a. This procedure generally is performed between L3 and L5.why do you think the fluid is withdrawn here rather than from higher up in the vertebral column?(hint:think about the structure and location of spinal cord b.often,the sampled CSF is tested for bacteria or virus if a brain infection is suspected.why would CSF sampled from the spinal cord give you information about the condition of the brain? c.would you withdraw CSF if the needle were accidentally inserted in to the epidural space instead of the subarachnoid space ?why or why not?arrow_forwardPlease I don’t not understand this question. An explanation leading to the CORRECT answer would be helpful! Question: Nancy K. was ice skating and had a really bad fall. She landed awkwardly on her back and an X-ray shows she shattered a vertebra near the bottom of the thoracic region (the T-11 vertebra; mid-lower back). Unfortunately, the break crushed her spinal cord in the region, and now her brain is no longer able to send or receive signals through spinal nerves below the fracture. Which body parts are LEAST likely to be paralyzed by this horrific accident?arrow_forward
- A common way to deliver anesthesia for surgery and child birth is to inject the anesthetic agent in to the epidural space (epidural anesthesia).why do you think the anesthetic is injected in to the epidural space instead of the subarachnoid space?arrow_forwardWhen their second child was born, Kiko and Taka were told their baby had spina bifida and would be kept in intensive care for a week. After that time, a “shunt” would be put in. Also, immediately after the birth, an operation was performed on the infant’s lower back. The parents were told that this operation went well but that their son would always be a “little weak in the ankles.” Explain the statements in quotation marks in more informative and precise language.arrow_forwardWhat is the primary difference between spinal and epidural anesthesia? The primary difference between spinal and epidural anesthesia is the site of a ministration of the anesthetic agent. The position of the patient and the skin injection site are similar. With spinal anesthesia, the medication injected directly into the cerebrospinal fluid (CSF) in the subarachnoid space between the meningeal layers of the spinal cord. With epidural anesthesia, the medication is injected into the tissues directly above the dura mater, where are the agent is then absorbed into the CSF.arrow_forward
- An intervertebral disc is a layer of cartilage that separates adjacent vertebrae in the spine. In terms of impulse, how does it protect the spinal system from damage during accidents?arrow_forwardPick one of the 12 cranial nerves and BRIEFLY describe its location, sensory, motor, or mixed, what structures it innervates, and function. As a nurse, what test would you perform on your patient to see if they have damage to this nerve?arrow_forward___10____ is a conspicuous fibrous tract (the narrator describes it as a “top lip”) deep within the brain that enables communication between the two cerebral hemispheres. Below it, the “bottom lip” is the fornix and the visible space between these 2 structures is called the __11_____. The brain has four ventricles, interconnecting chambers that produce and serve as a reservoir for cerebral spinal fluid.arrow_forward
- A 78-year-old male presents for a hospital follow-up, post-stroke, two days ago. During the neurologic portion of the physical exam, the patient cannot feel the cotton tip of an applicator as you brush it along his left forehead, cheek, and jaw on the left side of his face. Based on this scenario and phsyical exam findings, which of the following cranial nerves is most likely affected? Answers: A-D A Cranial nerve 9 B Cranial nerve 12 C Cranial nerve 5 D Cranial nerve 7 Oarrow_forwardInjury to the accessory nerve may result in sternocleidomastoid muscledysfunction, a condition called torticollis (sometimes called wry neck),in which the head is drawn to one side. If the head is turned to the left,does this position indicate injury to the left or the right spinal componentof the accessory nerve?arrow_forwardEach section of the spinal cord corresponds to a particular region on the body where sensory receptors are connected especially to the skin). These regions of the body are called _____. (plural, lowercase)arrow_forward
