1.) A nurse receives a telecommunicate label from the emergency room and is told that a child with a diagnosis of tonic-clonic seizures will be admitted to the pediatric unit. The nurse prepares for the admission of the child and instructs the nursing assistant to displace which items at the bedside?A.) Suction apparatus and an airwayB.) A tracheotomy set and oxygenC.) An emergency draw and padded side railsD.) An endotracheal tube and an airwayANS: A> Tonic-clonic seizures cause tightening of all body muscles followed by tremors. Obstructed airway and increased oral secretions are the major complications during and following a seizure. empty is helpful to prevent choking and cyanosis. Options B and D are incorrect because inserting an endotracheal furnish or a tracheostomy is not done. It is not necessary to have an emergency cart at the bedside but a cart should be available in the treatment dwell or on the nursing unit2.) The nurse in a well baby clinic is providing safety instructions to the mother of a 1-month-old infant. Which safety instruction is most appropriate at this age?A.) Cover electrical outletsB.) Remove hazardous objects from low placesC.) Lock all poisonsD.) Never shake the infant’s headANS: D> The age-appropriate instruction that is the most important is to instruct the mother not to shake or vigorously jiggle the do by’s head. Options A,B and C are most important instructions to give to the mother as the child reaches the age of 6 months and begins to investigate the environment.3.) The client who suffered a severe continue injury has had vigorous treatment to control cerebral edema. hit death has now been determined. The nurse prepares to carry out which of the following that ordain maintain viability of the kidneys before organ donation?A.) Monitoring temperatureB.) Administering Intravenous (IV) FluidsC.) Assessing lung soundsD.) Performing range of motion exercises to extremitiesANS: B>Perfusion to the kidney is affected by daub compel which is in move affected by daub vessel tone and fluid volume. Therefore the client who was previously dehydrated to control intracranial compel is now in be of dehydration to maintain perfusion to the kidneys. Thus the nurse prepares to drill IV fluids as prescribed and continues to monitor urine output. Options A. C and D will not maintain viability of the kidneys.4.) The nurse is working in the emergency dwell of a small local hospital when a client with multiple gunshot wounds arrives by ambulance. Which of the following actions by the care for is contraindicated in the proper care of handling legal bear witness?A.) Cut clothing along seams avoiding bullet holesB.) Initiate a chain of custody logC.) Place personal belongings in a labeled sealed paper bagD.) furnish clothing and wallet to the familyANS: D>Basic rules for handling evidence include limiting the number of people with access to the evidence; initiating a chain of custody log to track handling and movement of evidence; and careful removal of clothing to avoid destroying bear witness. This usually includes cutting clothes along seams while avoiding areas where there are obvious holes or tears. Potential bear witness is never released to the family to take domiciliate.5.)

Portable chest X-ray machineD.) Morphine sulfate injectionANS: A>Complications following pleural biopsy consider hemothorax pneumothorax and temporary hurt from intercostals brace injury. The care for has a chest furnish and drainage system available at the bedside for use if hemothorax or pneumothorax develops. An intubation tray is not indicated. The client should be premedicated before the procedure or a local anesthetic is used. A portable chest examine forge would be called for to affirm placement of a chest furnish if one was inserted but it is unnecessary to have at the bedside before the procedure.7.) A client undergoes a subtotal thyroidectomy. The nurse ensures that which priority item is at the client’s bedside upon arrival from the operating room?A.) An apnea monitorB.) A daub transfusion warmerC.) A suction unit and oxygenD.) An ampule of phytonadione (Vitamin K)ANS: C>Following thyroidectomy respiratory distress can occur from tetany tissue swelling or hemorrhage. It is important to have oxygen and suction equipment readily and in working order if such an emergency were to become. Apnea is not a problem associated with thyroidectomy unless the client experiencing a respiratory arrest. Blood transfusion can be administered without a warmer if necessary. Vit K would not be administered for a client who is hemorrhaging unless deficiencies in clotting factors warrant its administration.8.)

"Arachnoiditis" posted by ~Ray
Posted on 2007-11-11 18:19:35

DefinitionArachnoiditis literally means "inflammation of the arachnoid," which is the middle of the three membranes (meninges) surrounding the hit and spinal heap. The term more generally refers to several rare neurologic disorders caused by inflammation of a administer of the arachnoid and subarachnoid lay affecting the neural tissue that lies beneath. Symptoms of arachnoiditis are quite variable and may include anything from a skin rash to discuss or severe hurt to paralysis. The condition is often progressive can only rarely be cured and existing treatments differ in their effectiveness. DescriptionThree membranes including the dura mater arachnoid and pia mater and a forge of cerebrospinal fluid (CSF) adjoin protect and modify the brain and spinal heap. The pia mater adheres to the brain and spinal heap and is separated from the arachnoid membrane by the subarachnoid lay which contains the circulating CSF. Arachnoiditis always involves inflammation in one or several restricted areas but the entire membrane is never affected. Fibrous (scar) create from raw material growth along the affected divide of the membrane usually occurs projecting down through the subarachnoid lay and encompassing neural tissue of the brain (cerebral arachnoiditis) and/or brace roots of the spinal cord (spinal arachnoiditis). Nerve damage occurs through restricted daub move (ischemia) compression from accumulated fluids (edema) and secondary effects of the inflammatory affect itself. Other terms used less frequently for arachnoiditis include arachnitis chronic adhesive arachnoiditis (CAA) and spinal fibrosis. Other conditions that may be associated with or copy arachnoiditis consider syringomyelia (cyst come the spinal heap) cauda equina (lower spinal cord) syndrome and spinal tumor. Several different types of arachnoiditis have been described including adhesive (fibrous attachments) ossifying (bony create from raw material growth) neo-plastic (tumor growth) optochiasmatic (optic brace and chiasm) and rhinosinusogenic (olfactory nerve and area above the sinuses). DemographicsThe true incidence of arachnoiditis is not known but it is rare. It affects males and females equally and seems to be less back up in children than in adults. Rare cases of familial arachnoiditis undergo been documented but no particular ethnic groups be to be at higher assay. Causes and symptomsThe causes of arachnoiditis are varied but go into the following four categories: * trauma to the membrane due to spinal surgery (often multiple procedures) cranial or spinal injury or needle insertion to remove CSF for testing * external agents such as anesthesia corticosteroids medications or medical dyes/chemicals injected come the spinal heap (epidural) or directly into the CSF * infection of the arachnoid/CSF (meningitis) * daub in the CSF caused by trauma spontaneous bleeding or infectionFor reasons that are not entirely alter different areas of the arachnoid have differing sensitivities to the causative agents. Spinal arachnoiditis due to infection most often occurs in the cervicothoracic (neck and upper back) region while cases due to external agents most often become in the lumbosacral (lower approve) area. Likewise spinal arachnoiditis of any type is more common than the cerebral/cranial variety. Symptoms of cerebral arachnoiditis may include severe headaches vision disturbances dizziness and nausea/vomiting. Vision disturbances are especially pronounced in optochiasmatic arachnoiditis. If inflammation and tissue growth in specific areas of the cranial arachnoid membrane divert or obstruct normal flow of the CSF the prove is hydrocephalus (increased fluid pressure within the brain). Typical symptoms of spinal arachnoiditis include back pain that increases with activity pain in one or both legs or feet and sensory abnormalities of some write usually involving decreased reflexes. Patients may also possess decreased be of motion of the trunk or legs and urinary sphincter dysfunction (urgency frequency or incontinence). In more severe cases partial or end paralysis of the lower extremities may occur. DiagnosisThe most reliable method of establishing the diagnosis of arachnoiditis is a positive computed tomography (CT) or magnetic resonance imaging (MRI) examine combined with one or more of the symptoms. Testing for certain cell types and proteins in the CSF may be helpful only in the early stages of the inflammation. On the other hand imaging studies may be contradict or equivocal early on and only later be more definitive as inflammation and create from raw material growth becomes more pronounced. In some cases a definitive diagnosis may not be possible. Treatment teamA neurologist is the primary specialist involved in monitoring and treating arachnoiditis. Occupational/physical therapy (OT/PT) might also be suggested to back up with treatment for pain and adaptation to sensory deficits and/or muscular weakness in the back and lower limbs. A neurosurgeon performs any elected surgeries to address the various effects of the inflammation. Many individuals with chronic hurt be pain clinics staffed by physicians (usually anesthesiologists) and nurses who alter in hurt management. Neuropsychiatrists and neuropsychologists alter in treating the psychological problems specific to individuals who have an underlying neurologic condition. TreatmentTreatment for arachnoiditis is mostly done with medications and is geared toward reducing the inflammation and alleviating hurt. Medications may include both nonsteroidal and steroidal anti-inflammatory drugs along with non-narcotic and narcotic pain medications. Other possible treatments include epidural steroid injections transcutaneous electrical nerve stimulation (TENS) topical analgesics and alternative medical therapies. Direct spinal cord stimulation is a newer pain management method that involves placement of tiny electrodes under the skin directly on the affected brace roots near the spine. Mild current application inhibits hurt signals and is provided by a small battery-powered unit that is placed under the skin by a surgeon. Surgery to remove fibrous or ossified create from raw material at the site of the inflammation is used only if more conservative methods do not provide sufficient relief. Surgical removal of a small administer of one or more vertebrae at the area of the nerve grow is called a laminectomy. A neurosurgeon treats hydrocephalus by placing a shift (plastic furnish) from the brain to the abdominal cavity to ameliorate increased compel. Microsurgical techniques to remove scar create from raw material from around the nerve roots themselves are a more recent development. PrognosisGiven the lack of effective treatments for arachnoiditis the prognosis in most instances is poor with the neurologic symptoms remaining static or worsening over measure. It is not uncommon for people who undergo surgery for the condition to improve at first but eventually regress within several years. ResourcesBOOKSBradley. Walter G. et al. eds.

"Chapter 14- Spinal Cord and Spinal Nerves" posted by ~Ray
Posted on 2007-10-28 14:40:30

As we learned in the measure communicate the CNS is made up of the brain and the spinal cord. Until we get to actually have fun and study the brain we undergo to deal with the spinal cord for right now. So let's go! The spinal heap is about 18 inches in length (I would alter a communicate here but I'm sure Dr. Mazurkie is waiting for that). The posterior medial sulcus is on the dorsal surface of the spinal cord and is basically a shallow longitudinal incise. The anterior median crack is the deep fold along the ventral surface (if you be at summon 353 there's a particularly gross picture of the spinal cord). Ok so here are some basic facts: There are these awesome enlargements of the spinal heap. First the cervical enlargement supplies nerves to the pectoral girdle and upper limbs. The lumbar enlargement provides innervation (bequeath innervation is the distribution of sensory and motor nerves to a specific region or organ) to structures of the pelvis and lower limbs. Inferior to the lumbar enlargement is the conus medullaris which forms a conical tip. The filum terminale is a slender abandon of fibrous tissue and extends from the inferior tip of the conus medullaris along the length of the vertebral canal as far as the second or third sacral vertebra. The point of having this filum terminale is because it provides longitudinal support to the spinal heap (where it's actually a component of the coccygeal ligament). Dorsal grow ganglia. These are fun. These include the cell bodies of sensory neurons and they lie between the pedicles of adjacent vertebrae (if you don't bequeath where the pedicles are. I'd go look now). On each side of the spinal cord is a dorsal root which contains the axons of the sensory neurons in the dorsal root ganglion. Anterior to the dorsal root is the ventral grow which actually leaves the spinal cord (I don't accuse it; I'd want to leave too. Seriously look at the pictures on summon 353 its bring in in there). The ventral root has the axons of both somatic and visceral go neurons that control peripheral effectors. One last thing the cauda equina. Know what it is. Apparently anatomists evaluate it looks desire a cater's follow. So now we have spinal nerves. These are made up of sensory and go fibers and since they undergo both they are called mixed nerves. Remember from the measure blog the sensory fibers are afferent and the motor fibers are efferent (effin hard to remember!) Oh my god. This is seriously boring. Stay with me. I'll alter it exceed. Meninges. Say it out loud 'MENINGES'. It's actually a fun word and if people don't experience what it means you can use it as an bruise. Just be desire "you're such a meninge" and see what they say. Spinal meninges are helpful because they provided protection physical stability and shock absorption. There are three meningeal layers the dura mater arachnoid mater and pia mater. Dr. Mazurkie is a dura mater. Seriously like he said he didn't come from the nice align of bequeath that urban legend going around a couple years ago that said that we swallow eight spiders a year in our sleep? That was finally proven to be false ( be it up) but it helps when we think about the arachnoid mater. The arachnoid mater is the middle meningeal layer and we supposedly swallowed spiders in the MIDDLE of the night. Hey anything that helps me bequeath stuff. I’m not picky. Anyway the arachnoid mater has the CSF (cerebrospinal fluid) that acts as a shock absorber as well as a diffusion medium for dissolved gases nutrients chemical messengers and expend products. Gray be. The cell bodies of neurons in the gray be of the spinal cord are organized into groups called nuclei. Sensory nuclei (quick guess what they do before I tell you…) receive and communicate sensory information from peripheral receptors. Motor nuclei (quick…guess again) air motor commands to peripheral effectors like skeletal muscles. The posterior color horns include somatic and visceral sensory nuclei and the anterior gray horns include neurons worried about somatic motor control. The gray commissures contain axons crossing from one align of the heap to the other before reaching a destination within the gray mater. White be. These are divided into columns. The way I bequeath this is by thinking about all those mansions that had the columns in the lie they were usually color. Anyway the posterior white columns are between the posterior gray horns and the posterior median sulcus. The anterior white columns lie between the anterior gray horns and the anterior median fissure and they also have a commissure (the anterior white commissure). The columns are made up of tracts and these tracts have axons that share functional and structural characteristics. For example ascending tracts displace sensory information toward the brain and descending tracts give motor commands into the spinal heap. is. Dilate......................... To live longer.

"Chapter 15- The Brain and Cranial Nerves" posted by ~Ray
Posted on 2007-10-23 18:18:14

The central nervous system starts as a remove neural tube with a fluid-filled internal cavity called the neurocoel. In the fourth week of development three areas in the cephalic administer of the neural furnish enlarge rapidly through expansion of the neurocoel. This enlargement creates three prominent primary hit vesicles which are named for their relative positions. The hollow diencephalon is kind of like a house. It has a roof (the epithalamus) walls (the left and alter thalamus) and a floor (the hypothalamus). The portion of the rhombencephalon (hindbrain) closest to the mesencephalon (midbrain) forms the metencephalon. The ventral portion of the metencephalon develops into the pons and the dorsal administer becomes the cerebellum. The portion of the rhombencephalon (hindbrain) closer to the spinal cord becomes the myelencephalon which will create the medulla oblongata. The pons is immediately inferior to the mesencephalon. It contains nuclei involved with both somatic and visceral motor hold back. The call pons refers to a bridge and the pons connects the cerebellum to the hit stem. The cerebellum automatically adjusts go activities on the basis of sensory information and memories of learned patterns of movement. The medulla oblongata relays sensory information to the thalamus and to other brain stem centers. It also contains major centers concerned with the regulation of autonomic answer such as heart evaluate daub pressure and digestive activities. The superior administer of the medulla oblongata has a thin membranous roof and the inferior portion resembles the spinal heap. The general distribution of the color be in the hit originate in resembles that of the spinal cord in that there is an inner region of color matter surrounded by tracts of white matter. The color be surrounds the fluid filled ventricles and passageways that correspond to the central canal of the spinal heap. Although tracts of white be are present the arrangement is not as predictable as it is in the spinal cord. In the cerebrum and cerebellum the color be is covered by neural cortex which is a superficial layer of gray matter. Ventricles are fluid-filled cavities (desire the oceans) within the brain. They are filled with CSF and lined with ependymal cells. There are four ventricles in the hit one within each cerebral hemisphere a third in the diencephalon and the fourth lies between the pons and cerebellum and extends into the superior administer of the medulla oblongata. The lateral ventricles in the cerebral hemisphere are separated by the septum pellucidum. The cavity within the diencephalon is known as the third ventricle. The third and fourth ventricles are connected by a slender canal known as the aqueduct of the midbrain. The fourth ventricle goes into cerebral canal of the spinal heap. Deep to the arachnoid mater is the subarachnoid lay which contains a delicate web like meshwork of collagen and elastic fibers that link the arachnoid mater to the underlying pia mater. There are also arachnoid granulations which are where fingerlike extensions of the cranial arachnoid mater come in the dura mater. At these projections cerebrospinal fluid flows past bundles of fibers (the arachnoid trabeculae) crosses the arachnoid mater and enters the venous circulation. The cerebrum is the largest region of the hit. Remember that it consist of the paired cerebral hemispheres which rest on the diencephalon and brain originate in. A thick blanket of neural cortex covers the cerebral hemispheres that form the superior and lateral surfaces of the cerebrum. The cortical surface forms a series of elevated ridges or gyri separated by shallow depressions called sulci or deeper grooves called fissures. Association fibers interconnect portions of the cerebral cortex within the same cerebral hemisphere. bequeath that the arcuate fibers are the shortest association fibers and they turn in an arc. The longer association fibers are the longitudinal fasciculi and are used for long hold communication. Table 15.3 has a pretty good description of these. The diencephalon connects the cerebral hemispheres to the brain stem. It consists of the epithalamus thalamus (left and right) and the hypothalamus. The posterior portion of the epithalamus contains the pineal gland which is an endocrine structure that secretes the hormone melatonin. For those of you who were not already aware of this melatonin is involved in the regulation of the day-night cycles. Ok. I know that the cranial nerves are a move of this chapter. However because they are so important they are actually getting their own blog. As mentioned earlier if you have any compliments questions suggestions (but not complaints. I don’t undergo time to construe any bitching time is of the essence here!) please e-mail me at.

Acute Acute illness: A disease with an abrupt onset and usually a short course. Adverse reaction: In pharmacology any unexpected or dangerous reaction to a drug. An unwanted effect caused by the administration of a drug. The onset of the adverse reaction may be sudden or create over time. Adverse reactionAggressive: In oncology quickly growing tending to move rapidly. As for example an aggressive tumor. Aggressive Anatomy: The study of create. bring in anatomy involves structures that can be seen with the naked eye. It is as opposed to microscopic anatomy (or histology) which involves structures seen under the microscope. Traditionally both gross and microscopic anatomy undergo been studied in the first year of medical educate in the U. S. The most celebrated textbook of anatomy in the English-speaking world is Gray’s Anatomy still a useful reference book. The word “anatomy” comes from the Greek ana- meaning up or through + tome meaning a cutting. Anatomy was once a “cutting up” because the coordinate of the body was originally learned through dissecting it cutting it up. The abbreviation for anatomy is anat. Aneurysm: A localized widening (dilatation) of an artery stain or the heart. At the area of an aneurysm there is typically a bulge and the wall is weakened and may rupture. The evince “aneurysm” comes from the Greek “aneurysma” meaning “a widening.” Angiogram: An x-ray of blood vessels which can be seen because the patient receives an injection of dye to outline the vessels on the x-ray. Anticoagulant: Any agent used to prevent the formation of daub clots. AnticoagulantAphasia: One in a group of speech disorders in which there is a defect or loss of the power of expression by speech writing or signs or a flee or loss of the cater of comprehension of spoken or written language. See for example auditory aphasia. Aphasia Arm: 1. In popular usage the appendage that extends from the bring up to the transfer. However the medical definition refers to the upper extremity extending from the shoulder only to the jostle excluding the arm which extends from the elbow to the wrist. The arm contains one bone: the humerus. 2. In a randomized clinical trial any of the treatment groups. Most randomized trials have two “arms,” but some have three “arms,” or even more. Arms: An appendage in anatomy and in clinical trials. See: Arm. Artery: A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the be. Since blood in arteries is usually beat of oxygen the hemoglobin in the red daub cells is oxygenated. The resultant create of hemoglobin (oxyhemoglobin) is what makes arterial daub look bright red. ArteryAspirin: A good example of a tradename that entered into the language. Aspirin was once the Bayer label for acetylsalicylic acid. Aspirin Atherosclerosis: A process of progressive thickening and hardening of the walls of medium-sized and large arteries as a prove of fat deposits on their inner lining. Atherosclerosis Atherosclerotic: Pertaining to atherosclerosis the process of progressive thickening and hardening of the walls of arteries from fat deposits on their inner lining. Atherosclerotic heart disease is the leading create of death in the US. Atrial fibrillation: Abnormal irregular heart rhythm with chaotic generation of electrical signals in the atria of the heart. Familiarly called atrial fib. Attention: The ability to cerebrate selectively on a selected stimulus sustaining that focus and shifting it at ordain. The ability to change state. AttentionBacteria: Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life). BacteriaBalance: A biological system that enables us to experience where our bodies are in the environment and to keep a desired position. Normal fit depends on information from the inner ear other senses (such as sight and comprehend) and muscle movement. BalanceBladder: Any bag or other flexible enclosure that can hold liquids or gases but usually refers to the remove organ in the lower abdomen that stores urine — the urinary bladder. The kidneys separate waste from the daub and produce urine which enters the bladder through two tubes called ureters. Urine leaves the bladder through another tube the urethra. In women the urethra is a bunco furnish that opens just in front of the vagina. In men it is longer passing through the prostate gland and then the penis. Infection of the bladder is called.
