buy custom Why an Increase in Medical Radiation essay Medical radiation is a discipline in healthcare or medicine that is growing very fast. It has continually accepted the improvement in technology, digital imaging and instrumentation. Because of the increased improvements in technology, medical radiation has become one of the most advanced and dynamic areas of clinical medicine today (National Research Council, 2000). Even though there has been an increase in complaints of the harm that radiation has on human bodies, medical radiation of the right dosage is beneficial to human beings. As long as radiation is not abused then it can be of great benefits to human beings. Patients are usually constantly exposed to radiation rays. This occurrence is, however, the most popular with cancer patients who have to undergo the radiation process as part of their treatment. There has been an increase in the use of medical radiation in many medical centres even though there have also been improvements in technology. The increase in medical radiation doses is because of the many health benefits that radiation has on patients such as cancer ones. Patients are constantly exposed to radiation rays from diagnostic examinations even though the level or rate of exposure is generally low (National Research Council, 2000). The medical radiation doses have therefore increased because of the justified benefits of accurate diagnosis of the disease at hand. There has not been any valid and solid proof of radiation causing any harm especially at the low levels of exposure under which the diagnostic radiological examinations are carried out. According to Oxtoby (2007) there have been only theoretical evidence and no practical evidence of the harm caused by medical radiation. Even the theoretical evidence shows low cancer risks because of the low levels of radiation rays that are used during the examinations and diagnoses in medical radiation. Medical radiations have low risk levels as compared to the natural r adiation. The radiation doses given to patients should be regulated to ensure that they are not exposed to a lot of radiation rays which might be harmful to them. It is, however, very difficult to determine the right dosage for medical radiation. The dosage for medical radiation also varies between different cases of different patients. The dosage will also change depending on different variables that will have an effect on the whole radiation process, for example, the settings of the machine that is used to produce the radiation rays (Oxtoby, 2007). If the machine is set to produce more rays then the risks of exposure and harm from radiation rays will be more as compared to when the machine is set to release or produce little rays. Doses in Medical Radiation The radiation doses given to normal individuals or patients are different to that given to pregnant women. In medical radiation, high doses are given so that the cancer tissues can be destroyed. According to Powrie (2010) it is usually very tricky and challenging to give a dosage that is enough to destroy the cancer cells but at the same time not too much to have a negative effect on the patient or to be harmful to the patient. Special care is usually given to women who are pregnant. This is because of the sensitivity of the embryo to radiation. It is, therefore, advised that if there is a possibility of anothe option rather than radiation to be used on pregnant women then the other option should be fully utilized. If radiation dosage is necessary for the pregnant woman then precautions should be taken to ensure that the embryo is not affected or that the dosage is as little as possible to reduce the risks of exposure (Powrie, 2010). For patients who have a child bearing history or t he women who have had children before, a pregnancy test should be administered to them before they undergo any medical radiation process or examination. The dosage is usually regulated in different ways, for example, some techniques are usually used to focus the radiation dose only in the areas where the radiation rays are intended to reach while, on the other hand, administering lower doses to the normal tissues that are not affected. The radiation rays that are placed in direct contact with the tissues should be in very small quantities so as to avoid any harm that may be caused on the other healthy tissues that are around the cancer tissues. Risks of Medical Radiation Exposure There has been a constant debate on whether exposure to radiation rays is harmful or beneficial to human beings. The fact is that radiation can cause harm even though not practically proven and it also has its benefits. Every amount of radiation has an element of risk in it and, therefore, the greater the amount the greater the risk. The risks of harm from radiation as earlier mentioned depend on different factors such as the size of the dosage and the rate at which the dosage is administered. Other factors include the type of radiation ray that has been administered or prescribed and the age and health of the individual that is getting the dosage. Small doses of radiation usually increase the risk of getting cancer. Warrell (2003) explains that these risks are, however, small as compared to the risks posed from other factors different from radiation such as flying in airplane or driving a car. The risks of getting cancer from exposure to radiation rays is very small when the individ ual is exposed to other harmful factors such as smoking and alcohol which might also lead to the patient getting cancer. Many people, however, usually misperceived the risks of getting cancer from radiation exposure. This is because of the negativity that has been there towards the use of radiation for medical purposes. National Research Council (2000) believes that the effects of radiation on patients of human beings are divided into two categories, namely, stochastic and non-stochastic effects. The stochastic effects will be there even at low dosage of radiation because they do not have a threshold in which they occur. The non-stochastic effects occur only when the dosage exceeds a certain threshold for example if the radiation dosage is higher than normal. These effects are, however, not as severe as the stochastic effects. The risk of harm from radiation rays is different in different parts of the body. This is because different parts of the body have different levels of sensitivity towards the radiation rays. For example, radiation rays administered on the hand will have a different effect than the radiation dose administered on the reproductive areas. The effects in the reproductive area will be bigger because the reproductive area is more radiosensitive than the hand and, therefore, will bbe more and easily affected by the radiation dosage (Warrell, 2003). Managing Risks of Exposure to Radiation Radiation rays should be applied to only affected areas. This will help in reducing the risk of harm to other areas which are not affected. There should, therefore, be valid reasons why radiation dosages should be administered to a patient. For example, the patient has to be confirmed to be having cancer tissues before administering the radiation dose. A mere speculation is not enough reason and this may increase the risks of exposure. A justification is, therefore, needed for a radiation dose to be administered. The radiation dose should also be administered to the affected areas only by using the most dose effective settings on the machine administering the dose. This will ensure that very low levels of radiations are administered. Risks of exposure can also be reduced through consultations between patients and physicians before any dosage of radiation is administered Reasons for Increased Use of Medical Radiation There has been an increase in the use of medical radiation despite the constant developments in the technological fields that can be used instead of the radiation process. The growth has been caused by the increased usage of medical radiation or the increased use of radiation in medical services. The most well-known use of radiation for medical services is x-rays. X-rays are usually used to determine whether bones are broken. Yarbro (2011) further explains that other branches of radiology used for medical purposes are the mammography, computerized tomography which is popularly known as the CT scan and nuclear medicine. Cardiology is also another field of medicine where radiation is used. Radiation is also used for treatment of diseases such as cancer. The increased use of radiation technology in medical field has been because of the various benefits that radiation has on the field of medicine. X-ray is the field of medicine that uses radiation the most in detecting whether bones are broken or not. Despite the developments of new ways of detecting and treating broken limbs, the use of radiation rays is very important and almost mandatory in the confirmation that the limb is actually broken (Yarbro, 2011). Other technologies and methods might be important in speculating but it is the radiation rays that will confirm whether the limb is broken or not. There has also been an increase in the use of radiation despite the development of other methods and modern technologies because of the ability to control the risk of exposure of patients or healthy tissues to radiation rays. There are several ways in which the risk of exposure can be reduced when radiation is being used. The dosage of radiation is usually monitored and controlled throu gh the settings of the machine that is administering the radiation rays. This usually helps in reducing the levels or radiation rays that are administered to the affected areas and this will reduce the effects of the radiation rays on the healthy tissues that are surrounding the healthy tissues. Medical radiation will, therefore, be used more frequently even though there are new technologies that have been developed. This is because of its accuracy and its effectiveness in its treatments.

Nurse Prof Essay

Nurse Prof Essay Nurse Prof Essay HLTEN- Work in the nursing profession Assessment Task 2 CPD is the means by which members of the professions maintain, improve and broaden their knowledge, expertise and competence, and develop the personal and professional qualities required throughout their professional lives. CPD is defined as the education of health care professionals following completion of formal training. CPD consists of any educational activity which helps to maintain, develop or increase knowledge, problem-solving, technical skills or professional performance standards all with the goal that nurses can provide better health care. CPD includes 'formal' activities, e.g. courses, conferences and workshops, as well as self-directed activities .seminars, checking notice boards at work and ongoing research skills.Nurses are required to participate in at least 20 hours of continuing nursing professional development per year. One hour of active learning will equal one hour of CPD. It is the nurse responsibility to calculate how many hours of active learning have taken pl ace. The CPD must be relevant to the nurse context of practice. Nurses must keep written documentation of CPD that demonstrates evidence of completion of a minimum of 20 hours of CPD per year. Documentation of self-directed CPD must include dates, a brief description of the outcomes, and the number of hours spent in each activity. All evidence should be verified. It must demonstrate that the nurse has: Identified and prioritised their learning needs, based on an evaluation of their practice against the relevant competency or professional practice standards B) Developed a learning plan based on identified learning needs C) Participated in effective learning activities relevant to their learning needs D) Reflected on the value of the learning activities or the effect that The Board’s role includes monitoring the competence of nurses; the Board therefore conducts an annual audit of a number of nurses registered in Australia. The board also makes sure that they check the nurses’ criminal history for the protection of patients and their families. The Criminal history registration standard set out the factors the National Board will consider in deciding whether a health practitioner’s criminal history is relevant to the practice of their profession under the Health Practitioner Regulation. The standard has ten factors that they use when considering the outcome. The nature and gravity of the offence or alleged offence and its relevance to health practice. The more serious the offence the greater its relevance to health practice, the more weight that the Board will assign to it. The period of time since the health practitioner committed, or allegedly committed, the offence. The Board will generally place greater weight on more recent offences. Whether a finding of guilt or a conviction was recorded for the offence or a charge for the offence is still pending. In considering the relevance of the criminal history information, the Board is to regard to the type of criminal history information provided, the considered types are: Convictions Findings of guilt Pending charges The sentence imposed for the offence. The weight the Board will place on the sentence will generally increase as the significance of the sentence increases, including any custodial period imposed. The ages of the health practitioner and of any victim at the time the health practitioner committed, or allegedly committed, the offence. The Board may place less weight on offences committed when the applicant is younger, and particularly under 18 years of age.. Whether or not the conduct that constituted the offence or to which the charge relates has been decriminalised since the health practitioner committed, or allegedly committed, the offence. The Board will generally place less or no weight on offences that have been decriminalised since the health practitioner committed, or allegedly committed, the offence. The health

Characteristics of Millennial Generation Research Paper

Characteristics of Millennial Generation - Research Paper Example These children grew up in a period of increasing safety measures such as school lockdowns, car seats, and signs of body on board. These children are rarely left unattended to and are sheltered from taking care of their conflicts. Their parents advocate for them and spare them from experiences regarded unpleasant. American history movement on youth safety has focused on the millennial generation. Millennial are goal-oriented, confident and motivated in the future and in themselves. Millennial expect education institutions to push them to greatness. This group brags about their potential and power (Haugen 34). They are optimistic and feel connected to their guardian. They sacrifice their identities to be inside the team. Millennial prefers leadership of egalitarian but not hierarchies. This generation has formed a generation that is tight-knight. Millennial dislike standing out among their age mate, they prefer being part of the group. They are against selfishness and are directed towards volunteerism and learning. Grade point of this generation has risen and crime is falling. This group is oriented to hard work, getting good grades and involvement in co-curricular activities. They portray education as the key to a higher paying job and success (Haugen 44). Millennial always focus on their career since their grade school. They also focus more on the achievement of the world t han their personal development. Millennial generation are pressured; filled with activities that are structures. Additionally, they have problems of time management despite having more time for homework. Consequently, the millennial have pressure to make it in life. They have been pushed to succeed, avoid risks, and maximize on opportunities. Millennial are respectful and conventional; do not question authority. They believe on the nation to handle their issues and fear being seen as non-conformist. Their music, cultural marking, and clothing are

B2B Marketing Strategy Essay Example | Topics and Well Written Essays - 750 words

B2B Marketing Strategy - Essay Example Also, there should be a target of assigning the necessary resources to the segments that are being profitable. This strategy might not be immediately very profitable, as there will probably be some more inherent costs, even though some profit is expected, which will help in the company's actual financial situation. It is essential to start thinking about producing and marketing new products with the same characteristics which the actual consumers need. The products that the customers want to be on the market should be concentrated on, rather than continuing to offer the same customized products. I have learned from this simulation that in order to create demand, there has to be adequate investment in hiring of sales offices, web centers, customer service, promotions and advertising. I feel that for better profitability, there must be good relations with suppliers and customers. "Effective change requires reinforcing new behaviors, attitudes and organizational practices" (Kreitner & Kinicki, 2004). Also, having the right products, in the exact moment seems to require quite some time, and I think this is another important issue to be considered. When an organisation has produced the right product or services, they would want to deliver it according to current products and happenings in the actual market, and also according to what the competition is doing. I think it is important for the company to examine what the priorities are, and to review the currently established brand service prices. Effectiveness of Strategy According to Kreitner and Kinicki, there are three stages in this strategy or model of planned change, and this strategy is instrumental in initiating, managing and stabilizing the change process. The three stages of planned change are unfreezing, changing, and refreezing. Unfreezing focuses on creating the motivation to change, changing focuses on providing employees with new information, behavioral models and new ways of looking at things. Refreezing is the final stage used to help employees integrate the changed behavior into the every day process of doing business. Once employees are provided the opportunity to exhibit the new behavior, positive reinforcement is needed to reinforce the desire change (Kreitner & Kinicki, 2004) Works cited Kreitner, R., Kinicki, A.

Chemistry Research Part 1 Acids Essay Example for Free

Chemistry Research Part 1 Acids Essay Ethanoic acid is non-toxic and is a weak acid [4], meaning it will not do any damage to most surfaces as it does not corrode or bind to other metals, therefore can be easily removed through washing or rinsing it [2]. Disadvantages: Ethanoic Acid is the slowest de-scaler of the three acids, and is therefore the least effective. It also may cause an unpleasant smell, and can have a negative effect on the taste of coffee [6] meaning one would need to spend longer time rinsing and cleaning the machine thoroughly to ensure that the taste of the coffee is not affected. Citric Acid Advantages: Citric acid leaves behind zero toxic residues and has just enough acidic concentration to descale without etching or damaging household surfaces in any way and there are no volatile compounds or products that harm the environment. Disadvantages: Because citric acid is a weak acid, it wont remove heavy build-up of scale very quickly. It is also a powder hence it must be dissolved for use. It also works best with hot water meaning there will be higher energy consumption. Even when used with hot water, citric acid is not as effective at descaling as Sulfamic acid. Sulfamic Acid Advantages: Sulfamic acid is the fastest de-scaler It dissociates into hydroxonium ions more readily in aqueous solution than the others, therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5], which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers remove limescale Limescale forms when hard water is heated above 61Â °C or when it is left to evaporate on surfaces such as taps and showerheads. Hard water is water that contains high quantities of calcium and magnesium ions. These hardness minerals, in the form of calcium carbonate and magnesium carbonate, precipitate out of hard water to form limescale [1]. Therefore, to clean or remove limescale, something needs to dissolve or soften calcium carbonate and/or magnesium carbonate, so it can easily wash away. Acids cause mineral deposits such as rust to oxidise, thereby weakening them and making it possible to simply wash them away. Lime scale removers work by chemically reacting with the lime scale to form safe chemicals and ions. Lime scale is Calcium Carbonate, and when broken down by strong acids, produces Calcium Chloride, Water and CO2. These are much safer, and can be washed away with water, to remove the CaCl from the area.

Identity on the Internet :: Technology Computers

Identity on the Internet Before the internet, there was only the computer, large ones that take up a whole room. The computer then was seen only as a tool, and then a few years later there was the personal computer which made it more accessible and more interactive. The PC was a kind of evolutionary step which enabled us to have wider relationships. But these relationships did not appear yet until PCs started to become interconnected. This is where internet comes in. At first it was only a military tool, used by the States to connect their military branches and easily share their data. That was until someone saw the commercial value and the great potential of the net. In the article of Sherry Turkle, she described a new world where we have started to populate over the years with several mirrors of ourselves. The cyberspace is exactly that strange new world people have inhabited with the help of technology like the personal computer. With our lives now inside the screen and our personal selves cannot be determined by the other end then the internet, we gain the ability to recreate ourselves virt ually in the new world. We now have the ability to create characters will may or may not reflect our own identity. With MUD or multi user domains the characters we play can even have emotions that can be conveyed to a large number of other players residing in the cyber world. Through the interactions we have with players around the world, our real life personas, Turkle pointed out, go to â€Å"sleep† and our characters materialize inside the virtual domain. Players often border between real life (RL), a term coined by several MUD enthusiast and their cyber worlds and as a result there are several analogies that will work for this topic. Let’s take Play by Email (PBeM) as an example; this will be discussed further later on. The author is the player in cyber world and the interaction in the game is in the form of writing and the computer is the converter of simple words into the character’s actions, thoughts and feelings. Anonymity is a window to a new character. The internet also gives a person a chance to explore his other desires. He may be a man in RL but plays a woman in the game. She maybe a lawyer but plays a bartender.

Pet Peeve

Food! Oh my god I love food, and you can kind of tell. There so many different kinds. I enjoy the great satisfaction when I’m full. The only thing I don’t really like about food is seeing it in people’s mouths or hearing them chewing on their food. This is probably one of the things that irks me the most. If you want to make me leave a room, I have just clued you into a very simple way it can be done. Once I was at the theaters with my sister and two brothers going to see the movie Battle of Los Angeles. My sister asks if I can go get her some snacks and me being the kind person that I am I had no problems with that. I came back with couple of snacks some M&Ms, Reece’s Pieces, and chocolate covered raisins, my favorite. About halfway into the movie my sister grabs a handful of Reece’s Pieces, shoves it in her mouth and starts munching. CRUNCH! CRUNCH! CRUNCH! While her mouth was still full she makes a comment on the movie and SPLAT! Landed right on my face. She saw what she had done, not a big deal she apologized and I forgave her. Next, me and my mother went to a restaurant to eat breakfast. Everything was going all good. We were talking about her work, but once again someone had to talk while their mouth was full! She cuts a small piece of her pancake with her fork puts it in her mouth starts talking. I then look at her with a disgust look in my face and right when she said, â€Å"WHAT?! †I felt a piece of her food landed on my mouth. GROSS! I literally lost my appetite and didn’t really want to eat no more. I didn’t really say anything because if I did I knew she would of overreacted and got mad so I kept my mouth shut this time. Once more! When I thought that this wouldn’t happen to me again†¦ well at least not until awhile, but it did! About a couple days from my last incident it happened again, but this time it was worse. I didn’t even know the person. I was minding my own business talking to my friends then I hear this disgusting sound kind of sounded like a deer gnawing off its own leg? I turned around to see some guy eating an apple chewing with his mouth open. I really tried minding my own business really trying not to be the bad guy and say something, but then I felt something kind of wet, hit the back of my neck and couldn’t help but tell him. Of course I wasn’t rude about it I just told him if he can chew with his mouth close because it’s disgusting and a piece of it flew out of his mouth and landed on the back of my neck. Obviously he didn’t care or was too embarrass because he didn’t even speak. Couldn’t even say sorry at least. Some people are just rude these days. They should really start using their manners and close their mouth and keep it shut when they are eating. Its disgusting and nobody wants to see that! If they wanted to know what they are eating they would of asked! After all this had happen to me I really am annoyed with people who talk with their mouth full, chews with their mouth open, or chews really loud.
