The condition known as delirium

The condition known as delirium Introduction This assignment will examine the condition known as delirium and will focus on a clinical case study (please see appendix 1. for the full overview of the clinical case study) of a gentleman called Halim* who has presented in the emergency department with his two daughters. This assignment will be separated into two distinct parts; the first part of this assignment will provide a clinical overview of delirium and will explore what the condition is, the common features, clinical causes and interventions available to manage and treat the condition. This will provide the reader with an understanding of the components that constitute the condition of delirium. The second part of the assignment will then focus on placing the acquired knowledge of delirium on to the clinical case study of Halim so that a more detailed clinical exploration can be completed; with focus being placed on the role of the practitioner and their interventions in addressing the key issues. *To protect and respect client confidentiality all names have been changed and any identifiable data censored for the purpose of this assignment. Delirium Clinical Overview Delirium, also sometimes referred to as an acute confusional state, is a common clinical condition that presents with individuals experiencing disturbances in consciousness, cognitive function and perception, which has an acute onset and fluctuating course (NICE, 2010). The important clinical characteristic of a delirium is that the onset is quite rapid; it may present and develop within a very short period of time, usually over the course of a few hours or days (Brown Boyle, 2002). It is not uncommon for an individual to present to hospital settings with symptoms of delirium and it is important to acknowledge that individuals who already are hospital inpatients or in a care setting may also develop delirium; it is a condition that traverses the inpatient and community settings. Literature suggests that there are two types of delirium; hypoactive delirium is characterised by individuals experiencing withdrawal, lethargy, introversion and sleepiness whereas people with hyperactive delirium have heightened arousal, restlessness, agitation and aggression (NICE, 2010). There is also a third variation where individuals may experience a mixture of both hyper and hypoactive symptoms which can make diagnosis very difficult. It is suggested that delirium can often be mistaken for dementia, worsening of pre-existing cognitive problems and old age; however delirium is a clinical syndrome that differs from these other conditions as it is the sudden and acute onset that tends to vary throughout the course of the day that identifies it as delirium rather than any other disorder (Meagher, 2001). It is reported frequently within the literature (Wong et al., 2010; NICE, 2010; Meagher, 2001; Brown Boyle, 2002; Cole, 2004 and Siddiqi House, 2006) that patients with delirium experience a reduced ability to focus and concentrate; perceptual disturbances which includes delusions, paranoia and hallucinations; fluctuations in presentation; difficulty in following conversation or direction; rambling or changing topic; disorganised thinking and disturbances in consciousness. In addition to these clinical symptoms there also may be mood disturbances and changes in neurological presentation with individuals experiencing changes in muscle tone, tremor and involuntary jerking (Map of Medicine, 2011). Delirium occurs due to underlying physical pathology (American Psychiatric Association, 2000) and although symptoms may present as symptoms of mental illness the condition itself has originated usually from some kind of underlying infection, disease or event that has impacted on the individuals physical health status (Wong et al., 2010). Examples of possible causes for delirium include; hypovolaemic shock, cardiac failure, myocardial infarction, head trauma, seizure, metabolic disorders such as liver or renal failure, fluid and electrolyte imbalance, infection, malignancy, dehydration, post operative state, pain, constipation or urinary retention. In addition to these common causes delirium may also be induced by individuals experiencing complications from drug interactions and withdrawal; and included in this is prescribed medications, illicit drugs and alcohol (Map of Medicine, 2010). Delirium is a very serious condition and it cannot be underestimated as the mortality rate for individuals is very high even after discharge from hospital for up to 12 months (McCusker et al., 2002), other complications from delirium also include patients having to stay longer in hospital which means they are exposed longer to hospital acquired infections, persistent cognitive deficits and an increased risk of the individual being discharged into residential care rather than return to living independently are also factors (Wong et al., 2010). With the symptoms of delirium presenting as the onset of an acute mental illness it is possible for debate to arise as to which clinical team should be responsible for the management of the patient; additionally; in light of the evidence presented; it would be easy for the individual with delirium to be overlooked or not be investigated for the reasons behind the onset of the condition which is probably why the mortality rate is so high; underlying physical conditions that are not assessed, treated or managed will continue to affect the health status of the individual. Statistically more than half of delirium cases go unrecognised by health professionals (Inouye et al., 1998). Prevention of delirium is more effective than treating it once it has developed (Brown Boyle, 2002) therefore it is important for healthcare professionals to be aware of the risk factors, symptoms and causes of delirium for individuals under their care either in hospital or in the community. If delirium has already developed then it is the responsibility of the healthcare team to manage the condition quickly and efficiently to reduce further problems and difficulties for the individual; recognizing the mortality rates associated with a diagnosis of delirium should facilitate efficiency. To assist with obtaining a clearer clinical perspective of delirium and the impact it has on an individual a clinical case study shall now be explored. Halim Clinical Exploration Halim was admitted to the emergency department and when the clinical history was obtained from his daughters it was identified that there had been a rapid change in his cognitive status which had been observed within a 24 hour period as his daughter had not been alerted to any concerns when she had spoken to him the previous evening. In light of the evidence it is possible for practitioners at this point to consider that Halim has developed an acute syndrome such as delirium and the next stage is to explore this further. On completion of the basic observations it was evident that there are physical abnormalities present. From visual observation of the patient it is clear he has altered mental status, dry skin and cracked lips. From clinical measurement of heart rate, blood pressure, temperature and oxygen saturation levels, there is further evidence of physical abnormalities that may contribute to changes in cognitive function to such an acute degree. Obtaining clinical history often involves information being sought from third parties to support clinical findings particularly if the patient is impaired cognitively. Halims daughters were able to give an account of a gentleman who had experienced marital problems and divorce due to alcohol misuse and evidence remains that he continues to consume alcohol regularly. In addition to this there is a history reported of Halim neglecting his diet to the extent his daughters provide food for him when they visit, he also engages in health limiting behaviours by smoking and consuming high levels of caffeine on a daily basis. The history obtained from Halims daughters identifies a gentleman who is successfully self- employed, he has hobbies and interests although his social network has reduced and although he engages in health limiting behaviours such as smoking, drinking alcohol and neglecting his dietary needs; he has remained independent within his own home. The evidence suggests there has been an acute change and with this information and the clinical evidence indicating Halim is experiencing tachycardia, high temperature, hypotension and dehydration the clinical evidence provides a strong indication that he is experiencing symptoms of delirium. Further investigations are required to gain a greater understanding of what physical changes have occurred so that underlying causes are treated, however the practitioner should take some time to explain to the family members what tests are being completed and what the medical team are treating Halim for. The family must be very distressed by the changes to their father and by communicating the outcomes of the assessment and responding to any questions they may have will be beneficial as it is reported that the experience of delirium is frightening for both the patient and their carers and the value of reassurance cannot be underestimated (Mohta et al., 2003; Jacobson Schreibman, 1997). Managing Halim in terms of obtaining his consent to agree to treatment and investigations may be difficult because of the level of cognitive change and because his understanding and judgement may be impaired because of the delirium; therefore it is important that the practitioner and family are familiar with legal frameworks and hospital policies that are in place to ensure the rights of all parties are being protected. An example of this would be practitioners being familiar with the hospitals delirium policy, being well versed in patients rights and by having knowledge about legislation such as the Mental Capacity Act (The Stationary Office, 2005). As stated previously the experience of delirium may be frightening for Halim and therefore the practitioner should endeavour to implement nursing and care strategies that reduce distress, improve orientation, address physical health status and ultimately minimise the duration and impact of the delirium. Examples of the interventions that can be implemented include; working with the multi disciplinary team to treat the underlying cause of the delirium. This may include providing pain control, regulation of bowel and bladder function, ensuring adequate diet and fluid intake is promoted and recorded. Another intervention that is reported to be effective in supporting patients with delirium is for care staff to provide a safe and therapeutic environment. This would mean that Halim is offered reassurance and support, all activities are carefully explained; and for Halim this may mean that a Farsi speaking interpreter is found to facilitate communication between him and the medical team as he reverts to the language of his birth when speaking with the clinicians. In expanding the opportunity to communicate with Halim, this may increase his comprehension of what the medical team are trying to achieve and reassure him that the procedures being carried out; like attempting to obtain a urine screen. Due to the life threatening nature of Delirium it is essential for all physical screens and assessments to be carried out to ensure early identification of the reason for the onset of the condition, if the therapeutic interventions are unable to be implemented due to Halim remaining agitated and acutely confused then as a last resort medication may be considered in an attempt to reduce his level of arousal enough to ensure clinical procedures and care can be delivered. Psychotropic medication can be prescribed in delirium in an attempt to reduce the levels of distress and agitation and for Halim it may be beneficial to ease his levels of arousal enough so that medical interventions can take place; it is important to note however that psychotropic medications have side effects that include; extra pyramidal side effects, mobility impairment, sedation and cardiac interaction therefore they must be used with extreme caution and Halim should be monitored closely. Conclusion Halim has presented to the emergency department with a delirium and the impact of this on his health and welfare should not be underestimated by practitioners. With mortality rates in delirium being worthy to note it is essential that care pathways are developed to ensure the physical health and mental wellbeing of patients like Halim are met concurrently. Clinical, environmental and behavioural interventions are acknowledged to reduce the impact, intensity and duration of the condition; therefore practitioners should work intensively to ensure a delirium presentation is treated efficiently and effectively to ensure mortality rates are reduced and recovery is facilitated as quickly as possible.

Alexander Graham Bell Essay -- essays research papers

Alexander Graham Bell, a man who best known for inventing the telephone. Most people don’t know he spent the majority of his life teaching and helping the deaf. Educating the hearing impaired is what he wished to be remembered for.   Ã‚  Ã‚  Ã‚  Ã‚  Bell was born on March 3, 1847, in Edinburgh, Scotland. His mother was a painter of miniature portraits and also loved to play the piano even though she was nearly deaf. Aleck’s mother knew that he had a talent for music and always encouraged him to play (Matthews 12). Alexander Melville Bell, his father, was a â€Å"Professor of Elocution,† Art of public speaking (Bruce 16). Due to the fact that his father was a very knowledgeable man and a professor, Aleck obtained most of his education from his father and soon followed in his footsteps. Aleck had only two siblings, Melville James Bell, â€Å"Melly,† and Edward Charles Bell, â€Å"Ted† (Schuman 127).   Ã‚  Ã‚  Ã‚  Ã‚  Aleck’s father took a trip over seas in 1868 to see if Americans would take to his new ideas of speech. Alexander Melville Bell was so impressed that he decided to move the entire family. They did not purchase an estate in the United States. However they did buy an estate in Brantford, Ontario, Canada where there were an abundance of Scottish immigrants. Alexander Melville Bell still continued to make trips to Boston to lecture on â€Å"visible speech† (Schuman 39). Aleck’s father was offered a teaching position at the Boston School for the Deaf. He did not take the job but suggested that Aleck take the position instead. Alexander Graham Bell took the teaching position in April of 1871, and was on his way to the Boston School for the Deaf (Schuman 39).   Ã‚  Ã‚  Ã‚  Ã‚  Alexander Graham Bell’s, number one passion in life was helping the hearing impaired. Children learn to talk by hearing other people talk, and then they learn to speak by unconscious imitation. Deaf children do not have this option; they cannot imitate anything and therefore have to be taught by other means. Aleck thought that to teach a deaf child to speak consisted of having the child know how to make the sound by using different positions of their mouth. Slowly combining the sounds would make words and again would result in speech. Aleck tried a numerous number of methods. The method of Visible Speech was one of the ways that Aleck was able to teach his stude... ...lliant man and has changed the lives of many people around the world with or with out hearing impairment. His method of â€Å"Visual Speech† was great because it got the student to know how to use the organs in their mouths and be able to talk. To think that the telephone was originally going to be used as a device to help the hearing impaired is surprising because it ended up being used as a devise that people around the would use everyday to commutate. Alexander Graham Bell affected the world more directly by the invention of the telephone, but this could not compare to the gift of speech that he was able to offer to his students.

Problem solving Essay

Problem solving refers to the process of tackling a problem to try and solve it. In mathematics problem solving makes use of mathematical processes which enable pupils to develop new insights, and sometimes new procedures. It involves exploration, discovery and analysis. Problem solving begins with a task which the pupils understand and are willing to engage in, but for which they have no immediate solution. It is associated with developing and learning ways to tackle and solve problems. According to Broomes, Cumberbatch, James and Petty (1995) problem solving should no longer be viewed as an activity in which pupils engage after they have acquired certain mathematical concepts and skills. Problem solving should be viewed both as means of acquiring new mathematical knowledge and as a process for applying what has been previously learned. George Polya has also propose a four-step process for problem solving. These four steps are understand the problem, devise a strategy/plan for solving the problem, carry out the strategy/ plan and check for results or look back and check. These four steps are important in helping to do problem solving. The first stage of Polya’s problem solving is understanding the problem. In order for the students to solve a problem in a mathematics classroom they must first understand the problem or understand what they are asked to find or do. The problem must be read carefully then analyzed. Polya taught teachers to ask students questions such as:Do you understand all the words used in stating the problem?What are you asked to do or show?Can you restate the problem in your own words?Can you think of a picture or diagram that might help you understand the problem?Is there enough information to enable you to nd a solution? Polya’s Second Principle: Devise a plan Polya mentions that there are many reasonable ways to solve problems. The skill at choosing an appropriate strategy is best learned by solving many problems. You will nd choosing a strategy increasingly easy. A partial list of strategies is included: Guess and check Look for a pattern Make an orderly list Draw a picture Eliminate possibilities Solve a simpler problem Use symmetry Use a model Consider special cases Work backwards Use direct reasoning Use a formula Solve an equation Be ingenious 1Polya’s Third Principle: Carry out the plan This step is usually easier than devising the plan. In general, all you need is care and patience, given that you have the necessary skills. Persist with the plan that you have chosen. If it continues not to work discard it and choose another. Don’t be misled, this is how mathematics is done, even by professionals. Polya’s Fourth Principle: Look back Polya mentions that much can be gained by taking the time to reflect and look back at what you have done, what worked, and what didn’t. Doing this will enable you to predict what strategy to use to solve future problems. So starting on the next page, here is a summary, in the master’s own words, on strategies for attacking problems in mathematics class. This is taken from the book, How To Solve It, by George Polya, 2nd ed., Princeton University Press, 1957,

England Throughout History - 1724 Words

England. What is the first word you think of when you hear, England? You may think of their history and its effect. Another thought that could be is London. London is the capital and heart of England that has its own history. Throughout history England has contributed so much, good and bad. With that contribution England is one of the well most known country that is known for poise, history, and tradition. English history began in 500,000 BC with a boxgrove man from West Sussex. He was the first human known in England. In 55 BC Julius Ceasar invaded England for Rome. After Cesar took control Roman control lasted for 400 years. From 449-550 Jutes, Angles, and Saxons arrived in England and took control. In the beginning of the ninth century the Vikings came and invaded England. The Vikings controlled North and East England. In 897 Alfred the great defeated the vikings living in England. Another important date in England’s history is 1067 when the Tower of London began being structured. (England. China: CTSP, 2010. Print) In 1154 Henry II becomes the king. The next king, John became king in 1215 and signed the magna carta. 1348-49 was a hard time for England because the black death kills one third of the population. A long time after the black death was over in 1476 William Caxton set up England’s first printing service. In 1485 Henry VII is crowned the King of England.
