There could be some damage to the central nervous system but not very severe or the symptoms that Nick exhibits would be more severe. C. Diabetic neuropathies damage peripheral nerves. Which component of the reflex arc is most likely to be damaged in Nick’s situation? The component of the reflex arc that is most likely to be damaged in Nick’s situation would begin at the sensory neuron. Stimuli is still triggering the receptor but the information from the sensory neuron doesn’t continue the arc to the integrating centers to the motor neurons to the effectors which causes the absence of a reflex.
P3: Describe the investigations that are carried out to enable the diagnosis of these physiological disorders A service user would usually visit their GP if they suspect something is wrong with them; there are several different stages that would be followed prior to a diagnosis being reached. There are three types of referrals which can enable a service user to be a diagnosed Self-referral is when a patient refers themselves to health care professional, usually this is their GP. Professional referral is when a person goes to their GP and undergoes general tests, is examined after describing their symptoms and if their GP is concerned about their health, the GP will then make a referral to a specialist professional, for example a hospital doctor to see the patient immediately. The patient will then go on to see the doctor and then may go onto different specialists once a diagnosis has been made or is suspected. Another type of referral is third party referral.
D) Global aphasia. Diagnostic Tests The neurologist writes a diagnosis of, "Suspected brain attack" and prescribes a noncontrast computed tomography (CT) scan STAT. 4. Which nursing intervention should the nurse implement when preparing Nancy and her daughter for this
The nurse is caring for a middle-aged adult male client who is presenting to the emergency department with a severe headache, neck pain, and vomiting several hours after being involved in a motor-vehicle collision. The client is responding appropriately to verbal stimuli and is moving all extremities to command and contusions are noted around the cranium and left orbit. Questions: 1. Which assessments should the nurse perform at this time? List 3 assessments with rationales.
Outline and evaluate biological treatments of depression. 8 + 16 marks In the 1960s MAOIs were introduced after accidentally discovering that noradrenaline (a neurotransmitter) was a contributing factor in depression. MAOIs work by blocking the action of monoamine oxidase, an enzyme which flushes noradrenaline out of the synapse. This means that there is more noradrenaline available in the synapse which will, hopefully, result in relieving the symptoms of depression. MAOIs were effective for some people, but they came with severe side effects and in some cases even death when taken with certain food and drink such as marmite and red wine due to a sudden and massive increase in blood pressure.
Some drugs work by increasing the levels of neurotransmitter as low levels of serotonin are thought to cause depression so SSRI drugs such as Prozac are used to block the re-uptake pump in the synapse. This reduces the rate of re-absorption therefore increasing serotonin levels by allowing more serotonin to attach to receptors. Other drugs such as anti-psychotics block the post-synaptic receptor sites so that not as much dopamine can cross the synapse. This relieves the symptoms of schizophrenia by decreasing excessive dopamine levels. Many drug treatments are cost effective, easy to use and there is much evidence to show that drugs can be effective in a range of psychological disorders, such as up to 70 per cent of depressed people respond to drug therapy.
Removing VLCSFA from the diet eliminates any external contribution to the total VLCSFA blood level. Lorenzo’s Oil, made of monounsaturated fatty acids (good fatty acids), causes Competitive Inhibition to occur. The same enzyme complex that elongates fatty acid chains becomes occupied with the production of monounsaturated fatty acids. The enzyme complex cannot produce both types of fatty acids simultaneously. Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA.
Question 1 - INCORRECT | Your patient is admitted with a diagnosis of a intracerebral hemorrhage due to an aneurysm. On admission your patient’s pupils were equal and reactive to light, she had a slight drift of the right arm and complaints of a headache and nausea. About 15 minutes later she is unresponsive and her pupils are dilated and react sluggishly. You would anticipate her treatment is likely to include: | | | Your Answer: | Administration of t-PA | | Rationale: Incorrect. Please review Module 5, Lesson 4, Topic 4 | | A surgical aneurysm clipping | | Rationale:Correct | | | Question 2 - Correct | The clinical presentation of a patient with a brain tumor depends on the location of the tumor.
This deletion causes the amino acid phenylalanine to be removed. Normally, after CFTR has been synthesized, it is moved to the endoplasmic reticulum and Golgi apparatus for final modifications before it becomes incorporated into the cell membrane. However, in patients with cystic fibrosis, when the defective CFTR protein reaches the endoplasmic reticulum and Golgi apparatus, it is unrecognizable because the protein has been folded improperly. As a result, the effectiveness of the
'Describe and evaluate two theories of addictive behaviour, in initiation, maintenance, and relapse' Biological models of addictive behaviour focus on the neurotransmitter substances in the brain, and on genetic differences between people with addictions and people without addictions. Biological models of addictive behaviour, it seen that a person would be most susceptible to addiction during the initiation phase, because they have a predisposed biological vulnerability. Such biological predispositions are less likely to have an effect during the maintenance of the addiction. However if a person managed to give up their addiction, a biological predisposition would make them more susceptible to relapse. The neurotransmitter that is most
