Should smoking be banned in public places Essay

Should smoking be banned in public places - Essay Example There are studies to prove this case. Even though there are no laws that prohibit smokers from smoking, the places where cigarette smoking should be allowed can be regulated. Banning cigarette smoking in public places will do a lot in preventing illnesses caused by passive smoke. Smoking as a habit has been around for a long time now, and it has been regarded as both a bad habit and symbol of status. Up until the nineteenth century, cigar-smoking was almost exclusively done by socially elite males. Cigarettes were actually derived from cigars as they were essentially tobacco residues which were swept and collected and later on smoked by poor people. Cigarette smoking then became popular in the 1880's, with the advent of cigarette-making machines. Though cigarettes were cheaper and widely available, smoking it was still not popular at that time. Cigarette smoking just became popular World War I when tobacco companies gave away large quantities of cigarettes to American soldiers to boost their morale. Only after this event that Americans were hooked to cigarette smoking (Grannis, n.d.). It was only after a few years of research that people learned of the harmful effects of cigarette smoking. One of the Surgeon General's findings was cigarette smoking was not o nly harmful to the smoker but also to the non-smokers (commonly referred to as passive or second-hand smokers) surrounding them. As a result several action groups sought total cigarette bans on shopping malls, theaters and other public places. Bad effects of smoking Various cancers were eventually found out to be linked with cigarette smoking. These cancers develop due to the 43 carcinogens and other chemicals found in cigarette smoke, leading to carcinogenesis or the formation of cancer causing cells due to smoking (Burns, 1991). In the 1950's, extensive research about the relationship between lung cancer and cigarette smoking were done in the U.K. and the United States. Findings from these studies showed that smoking and lung cancer were indeed related. Previously, lung cancer was one of the rarest types of cancers in the world. In the 1970's, cases of lung cancer suddenly boomed when cigarette smoking went popular during the period. This sudden increase made lung cancer into one of the deadliest cancers in the world (qtd. From Grannis, n.d.). Lungs are not the only organs in the body that are affected by cigarette smoking. The brain and the rest of the nervous system is also affected by cigarette smoke. The brain's cognitive functions which handles the brain's capacity for stimuli and attention as well as regulation of automatic body processes such as digestion and breathing is negatively affected by cigarette smoke. This happens when blood containing carcinogens are pumped into the brain's bloodstream. Different carcinogens have different physiological effects. For example, nicotine acts upon the brain within 10 seconds, causing an almost instantaneous mood change in the user ("TheHealthConsequencesofSmoking.." 2005). Independent studies made in the University of Aberdeen and University of Edinburgh investigated the various effects of smoking in the cognitive skills of smokers and non-smokers. The results, published in an issue of New Scientist showed that most smokers fail in five unrelated cognitive tests. Another series of tests

Role of the nurse Essay Example for Free

Role of the nurse Essay According to the American Nurses Association the role of the professional nurse is held to a high standard. Nurses have a guideline of professionalism that is upheld to match the level of care given to each and every patient and held accountable for their actions towards clients and peers (Perry/Potter, 7). Nurses are expected to critical think as a way to solve any problem or ailment presented to them by patients. Nurses are to implement the nursing process which delegates a step by step process to think critically in solving patients problems. The steps are assessment, diagnosis, outcomes identification and planning, implementation and evaluation (Perry/Pottery, 7). 2. I see nurses fulfilling these roles and many more. The nurse is a caregiver when attending to patients needs and going the extra mile in providing care that is not asked for, such as when providing a bath and massaging the legs to provide stimulation in circulation in the legs. Nurses are the patient’s advocate we speak on the patients behalf to the doctors as well as administration. Educating the patient on prevention of illness and health practices on current ailments. We communicate to the patients on a daily bases nurses are on the forefront dealing with the patients at the bedside we communicate all needs and care for the patient to the doctors. Nurses are in charge of managing the care of our patients how the patient is responding to treatment, their fluid intake and output, tracking of nutritional status. Nurses practice autonomy and accountability on a daily basis. We encourage ambulation to a patient after giving birth to stimulate circulation and urinary functions. 3. When I think of a nurse I think of a caregiver. Someone who will help a patient on their road to recovery. Someone who will listen to a patients concerns and reassure the patient that they are receiving the best care possible. Someone who will care. In my opinion some people think that nurses are assists to doctors. I have heard this many times. Yes we do assist doctors but today nurses are so much more and are responsible for much more in the medical field. Mostly the media presents nurses in a positive light showcasing the diverse and important role of the nurse in the hospital. But sadly there are still some that negatively show nurses as a sex symbol with no real input in patient care.

Impacts of Dehydration on the Body

Impacts of Dehydration on the Body Helen McHugh Why is dehydration and electrolyte imbalance a danger? Dehydration is described as ‘an excessive loss of water from body tissues’ (Mosby Elsevier, 2009) and it also affects an imbalance of electrolytes in the body. It can be very dangerous and even fatal as most of the physiological systems in the body are dependent on water levels and the changes in concentrations of the electrolytes will disturb almost every vital function of the body. (Martini Nath, 2009) How have the functions of the skin been impaired? The body’s first line of defence has been breached, allowing pathogens and bacteria to penetrate the body as well as impairing its ability to regulate temperature, synthesis Vitamin D and loss of some senses i.e. touch, pressure. How will the body try and repair the areas that have been burnt? This will happen in three stages, Inflammation, Reconstruction and Maturation. Inflammation – this stage takes approximately 3 days and happens immediately the wound occurs. The inflammation causes an increased blood flow to surrounding tissues which produces erythema, swelling, heat and discomfort. As a defence response, different types of white blood cells called polymorphonuclear leucocytes arrive at the wound and are involved in the immune response to fight infection. Reconstruction This stage can take from between 2 – 24 days and is a time of cleaning and temporary replacement of tissue. Polymorphs kill the bacteria and phagocytic macrophages digest the dead bacteria and clean the wound. Epidermal cells start to activate, new blood capillaries are developed and granulation tissue is laid down. Epithelial cells move over the granulation from the edges of the wound. When the wound is covered the epithelium thickens to 4-5 layers, forming the epidermis. The wound would then start to contract reducing in size. Maturation – This stage can take between 24 days to 1 year. This is the remodeling stage where collagen cells are reorganized and strengthened. The wound is still at risk during this stage and protection is necessary. (Koutoukidis, et al., 2013) What could impede the body from successfully achieving this? Think of internal and external factors when you answer this. Intrinsic- (Internal) Health Status – Illnesses/Conditions/Diseases can affect healing, i.e. anaemia, immune disorders, cancer, diabetes. Age – Older people take longer to heal due to slower metabolism, thinner skin and less elasticity of skin. Bodybuild – Both Obese and Thin people can have various issues related to healing Lifestyle factors – Smoking, Alcohol can have contraindications to healing Nutritional status Extrinsic (External) Mechanical stress Debris – scabs, necrotic tissue, and excess slough can all impair epithelial migration and supply of nutrient. Also prolongs inflammatory stage. Temperature – Extremes can cause tissue damage Desiccation or maceration – Both dryness and excess moisture can slow healing Infection – Bacteria slows wound healing Chemical stress (Lumsden, 2014) Mary undergoes debridement of the burns. What does this mean? Debridement is the first step in cleansing. It is to remove dirt, foreign objects, damaged tissue and cellular debris from wound/burn which promotes healing and helps prevent infection. (Mosby Elsevier, 2009) The burns were subsequently grafted with a split skin graft. What layers of the skin are used for this graft? A split thickness skin graft is a tissue transplant using both the epidermis and part of the dermis layer. (Mosby Elsevier, 2009) 3.1 Admission Form Acute Pain Observation Chart Observation chart Fluid Balance Chart Medication Chart Neurovascular Chart Intravenous Drug Chart Care Plan Progress Notes 4.2 Define Hypertension and Arteriosclerosis Hypertension – Elevated blood pressure consistently over 140/90 Arteriosclerosis A thickening/ calcification of arterial walls and loss of elasticity in arterial walls. The result of this is reduced blood supply. (Mosby Elsevier, 2009) How are they often related? High blood pressure (hypertension) can cause a build up of the muscular and elastic tissues of the arterial walls – hypertensive arteriosclerosis (Mosby Elsevier, 2009) Why is hypertension called the ‘Silent killer’ Hypertension is called the silent killer because it can often be asymptomatic, i.e. no symptoms are apparent. There is no single cause but there are possible risk factors. (Mosby Elsevier, 2009) Name three changes in your lifestyle that may help prevent cardiovascular disease in old age. Do not smoke, Eat healthy and exercise more. Undesirable clot formation can occur as a result of endothelial damage due to arteriosclerosis. How does the body form undesirable clots within intact blood vessels? If the endothelium of a blood vessel is rough it can encourage clinging of platelets which can be a risk factor for blood clotting (Thrombus) The legs are particularly prone to the formation of blood clots and can be caused by blood pooling in the legs or slowly flowing blood especially in immobilized patients. (Marieb, 2003) 5.2 At handover you are told a patient is cyanotic. What would you expect to observe? Define tissue hypoxia. Three conditions where this could occur. Cyanosis presents as a bluish discolouration of the skin and mucous membranes caused by not enough oxygen in the blood and excess of deoxygenated blood. I would expect to see a bluish colour on the skin of the patient, possibly on lips, nailbeds, tip of the nose, external ear and underside of the tongue. Three conditions where this could occur are Asthma Emphysema Heart failure 5.3 Describe the difference between tracheostomy and endotracheal intubation. An endotracheal intubation is a flexible cuffed tube inserted via the mouth or nostril through the larynx into the trachea, whereas a tracheostomy is a surgical creation of an external opening into the trachea. (Koutoukidis, et al., 2013) 5.4 Why will a patient who is anaemic complain of shortness of breath? Being anaemic means that you do not have enough red blood cells in your body. The red bolos cells carry oxygen around the body and remove carbon dioxide. Fewer less red blood cells equals less oxygen which equals shortness of breath. (Koutoukidis, et al., 2013) 5.5. What type of allergic reaction is suspected? Anaphylaxis is suspected. This condition may be fatal. Why has this caused problems with his breathing? The upper respiratory tract is often involved with nasal congestion or sneezing and tightness in the throat may occur with significant airway obstruction. The patient can have bronchospasm or upper airway swelling (S Shahzad Mustafa, 2013) 6.1 Sever appendicitis, what would be result if left untreated? The appendix can perforate spilling the contents into the abdominal cavity causing peritonitis. (Koutoukidis, et al., 2013) 6.2 Why does a lack of fibre in the diet encourage the formation of diverticula? Faeces usually move along the large bowel with gentle peristalsis; however when there is insufficient fibre in the diet the faeces may become dry and is more difficult to move along with peristalsis. The intestinal muscles then have to perform strong contractions and generate high pressure. This high pressure may cause bulging pouches in the intestinal mucosa and these are called diverticula. (Murtagh, 1995) 6.3 Explain why obstruction in the common bile duct causes interference with the digestion of some foods? An Obstruction would prevent bile from entering the small intestine. The bile is needed to aid digestion and is needed to breakdown large fat globules into small ones. When the food is not digesting properly bile can back up into the gallbladder. It then becomes concentrated by removal of water and the cholesterol it contains may crystallize and form gallstones. Blockage of the common bile duct can also stop bile entering the small intestine and backing up into the liver and bile salts and bile pigments will begin to enter the bloodstream and as this circulates through the body the tissues will become yellow or jaundiced. (Marieb, 2003) 6.4 What nursing observations of their skin, faeces and urine would support the diagnosis of an obstructed bile duct? Where would these observations be recorded? Bilirubin levels will increase in the blood and this can cause yellow, jaundiced skin, dark urine and pale coloured faeces. Itching of the skin may also occur. Recorded in progress notes, fluid balance and bowel chart and observation chart, care plan and urinalysis. (Marieb, 2003) 8.2 Adrenaline affects the sympathetic nervous system. Explain the effect on blood pressure, heart beat, breathing and the liver. Blood Vessels – Constricts blood vessels In viscera and skin, increases blood pressure Heart – Increases rate and force Liver – Causes glucose to be released to blood. All of these effects are part of the fight or flight response. The body alters its normal state to one of optimum performance in order for us to take flight (run faster) the heart beat starts to pound, our breathing gets deeper, driving oxygen around the body and glucose is released into the blood stream to give us energy. (Marieb, 2003) 9.1 Explain why someone who is haemorrhaging, i.e. has falling systemic blood pressure/volume will have a decreased urine output. When there is significant blood loss the blood pressure falls and the blood pressure in the renal artery will also fall. The body tries to raise the blood pressure by preventing further water and electrolyte loss. To do this the kidney secretes the hormone ‘renin’ which stimulates other hormones to cause vasoconstriction (Marieb, 2003) References: Koutoukidis, G., Stainton, K. Hughson, J., 2013.

Kailey Knowles Period 2 December 10, 2013 Oedipus Cycle Analysis Creon as a Tragic Hero As once said by Aristotle, "A man doesn't become a hero until he can see the root of his own downfall". A tragic hero is often seen as someone with great stature who is noble yet imperfect, and experiences suffering due a moral flaw. In Sophocles’ Ancient Greek play The Oedipus Cycle, Creon represents the true tragic hero when his flawed actions and excessive pride create the path towards his demise. Creon’s declination begins in Oedipus at Colonus when his infatuation with power and control begins to arise, in turn bringing forth a rigid side to his character. The battle over the kingship of Thebes is a pivotal point in Creon’s development. He goes to drastic measures when threatening the lives of Oedipus’ daughters in order to bring him back to Thebes, and in conversation with Oedipus, Creon says, â€Å"Your daughters: one of them I have just now / Had seized and carried off; now I’ll take this one† (129). His forceful and domineering actions towards his brother-in-law begin to peel back the layers of his intentions. In Oedipus Rex, Creon did not want the throne, nor did he enjoy attention, but he now finds pleasure in being the head figure of leadership. The first signs of Creon’s craving for personal pleasures are unravelled as he begins to act under the influence of his Id, â€Å"a demand to take care of needs immediately† (Bo eree). The animalistic tendencies, destructive nature, and amoral actions are all induced by the Id, and Creon unconsciously begins to tap into that part of his mind as he strives to gain power. All other emotions and opinions of others are disregarded and Creon makes it his goal to become king, seemingly stopping at nothing t... ...ng presence of his superego that was lacking throughout the earlier areas of his life. Superego is the â€Å"internalization of punishments and warnings† (Boeree) which plays a part in Creon’s growth of emotions that he struggled with early on. His previous impulses of pleasure and aggressions have been masked by his superego. Creon’s ability to have an anagnorisis in Antigone helps contribute to his role as a tragic hero. The once King of Thebes had everything in life to be content with, but the relentless attitude of his own superiority ushered him to his downfall. While he lost his grip on his relations with others and experienced an overwhelming influence of his Id, and it was too late by the time he realized, Creon nonetheless had an epiphany about his actions and understood his faults. Through his perils and travails, Creon earns the title of a true tragic hero.

Definition Paper- Beauty Is Not in the Eyes of the Beholder

UC-110 31 October 2012 Beauty What does it mean to have beauty? What is beauty really? Questions like these can be explained through the definition of beauty. The problem is that beauty in today’s society has acquired multiple meanings. How many times has one heard the phrase, beauty is in the eyes of the beholder, or how about, beauty is on the inside? These happen to be common misconceptions. The true definition of beauty is ironically hidden behind a mask of deception. Glancing through history brings to light the harsh reality of what beauty was and still is today.Individuals need to look beyond the common myth that beauty is merely subjective. Beauty is a perceptual quality that is a product of innate human design. Love it or hate it, from the moment you opened your eyes, beauty was already defined. Going back in time and reviewing the evolution of beauty demonstrates the definition, as well as disproving beauty is merely subjective. The Darwin theory of beauty is scientif ic evidence that there is a reason for universal aesthetic pleasure.Dennis Dutton, a scientist and philosopher states, â€Å"Beauty is an adaptive effect in which we extend and intensify in the creation of works of art and in the identification of human beings. † Dutton pronounced this statement after studying the universality of beauty across a wide range of topics. It is impossible that humans all perceive the same qualities as unique and aesthetically pleasing when we live in such diverse places. Sexual evolution plays an important role in defining beauty as a product of innate human design. The peacock for example contains beautiful feathers that in no way help with basic survival.However, the peahen is extremely attracted to the peacock because of its feathers, they are aesthetically pleasing. The peacock proves that mammals are born with qualities that bring about pleasure rather than survival. Humans are in this category with mammals. Humans contain symmetrically pleas ing elements that have little to do with survival. These elements are what prove that beauty is innate. Beauty may have scientifically evolved into what individuals perceive it as today, but the aspect of science has been removed from the concept itself.Confidence is another concept that finds itself in the same position as beauty. Confidence, by society has been changed to be a quality in which anyone can radiate through their â€Å"swag. † In reality, just like beauty not everyone can radiate confidence. Christopher Cardoso reported, â€Å"Confidence and positive self-image is just a balance of hormones. Oxytocin is responsible for what a lot of us think is confidence around our peers. † Beauty is the same way, â€Å"It turns out standards of beauty are not only the same across individuals and cultures, they are also innate.We are born with the notion of who’s beautiful and who’s not† (Satoshi Kanazawa). In fact studies have shown that infants (w ho have had no environmental exposure) stare at the faces of adults that are considered beautiful by other adults longer than those who are not considered beautiful. An infant is incapable of developing perceptual knowledge based on its environment about what is aesthetically pleasing. Without determining the effects and causes of this definition, it would be unjust to define beauty as a perceptual quality that is a product of innate human design.Models starve to be perceived as beautiful, while others make a living on determining who will be considered aesthetically pleasing. The society in which we live in from Australia to the United States all puts beautiful people and items on a pedestal. Unfortunately, because beauty is not in the eyes of the beholder, people will search their whole lives to become roles in society that require beauty. Devoted to a lost cause, some will never be successful. Beauty has become an industry of manipulators that try to prove to those who were not b orn with the innate quality of beauty that synthetic things can get them there.In societies that can sometimes over look individuals’ feelings and emotions, a scientific definition of beauty might appear harsh. This explains why alternate definitions have shown prevalence, with beauty as a subjective concept. As it can be useful to define beauty in terms of the â€Å"beholder,† it is more important to recognize a definition that is scientifically proven. It is important that individuals can accept that beauty is in fact a perceptual quality, but one that is a product of innate human design.

Bio animals essays

Bio animals essays 1.) Chordates are animals that posses a notochord, a hollow dorsal nerve cord, and pharyngeal slits at some point in its development. 2.) Vertebrates have a backbone, an endoskeleton, or skeleton on the inside of the body, a large brain in a skull, a large brain in a skull, an advanced nervous system. A complex heart and circulatory system, a special kind of outer covering, one or two pairs of appendages. 3.) The five classes of a vertebrate are the fish, amphibian, reptile, bird, and mammal classes. 4.) Lampreys are parasites. They have a circular mouth with teeth on their tongues, which they use to attach themselves to another fishs body. When they attach to the fishes(host) they scrap away at the skin with their large teeth and a strong, rasping tongue. They then suck up the tissues and the body fluids of the fish(host). They are not true fishes because they have no bones what so ever. They are the only vertebrates that do not have backbone as adults. 5.) Sharks are not true fish because they do not have scales or bones in their skeleton. The also do not have a flap of skin covering their gills as some other fishes do. Sharks just have five to seven rows of slits. 6.) Cartilage is a tough tissue that bends easily. 7.) A shark must keep swimming all the time to keep water flowing across its gills to enable it to breathe. 8.) True fishes have a bony skeleton and are covered with scales. Bony fish are what people commonly call fish. Some characteristics of true fish are skeleton of bones covered with scales, fins for swimming, gills for breathing, two-chambered heart, cold-blooded. 9.) Some fish have a swim bladder, a gas filled bag that enable them to go from shallow to deep water. 10.) Fish obtain oxygen by gulping water and passing the water over their gills. And the gills absorb the oxygen from the water, and the water is passed, by osmosis to the blood vessel. 11.) Cold-blooded mean their body tem ...
