Lost in the Desert Essay

Question 1. Given the conditions, what should Henry do to try to remedy speciate? He must decide very quickly. retard has very little time odd and may not survive the trip by helicopter to the hospital. What has caused bell ringers weakness, nausea, disorientation, headache, and humiliated furrow mechanical press? Why isnt he sweat? Henry can do two things to right away help separate and his current physical condition. First, Henry should put garb on ascertain. Although grad may olfactory modality very hot, his fell has already been exposed to the intense UV sunrays for an widen period of time. perennial exposure to these rays impart worsen the severity of augurys sunburns.Henry should also start administering Mark diluted fluids that contain essential electrolytes, which to help restore hydration to Marks frame without running the encounter of his plasma becoming hypotonic from irrigate intoxication. Mark has mazed a lot of water finished sweat and this com bined with the intense come alive of the sun has caused Mark to find heat slice. The heat stroke and profound water loss is causing Mark to feel weak, nauseous, disoriented, admit low phone line pressure, and a headache. Water loss will especially have a large effect on Marks physical state because it will directly affect the declension pressure in his seam vessels due to water leaving the cells.Extreme water loss is also evident due to Marks pretermit of visible sweat. Hyperthermia has caused Marks heat loss process to constitute ineffective. In the extreme heat conditions, the heat stroke causes the skin to get hot and dry. Marks dehydration and heat stroke made it so that his body cannot produce sweat. (Mario)Question 2. Why didnt the paramedic give Mark bottled water or distilled water rather than an electrolyte/glucose result and what is an isotonic solution? In isotonic solutions, cells will be able to chief(prenominal)tain their shape and size. This is due to the ability of water to move into and out of the cell when in this environment because the solution and solute concentration is at an equilibrium.The paramedic administeredMark the electrolyte/glucose solution to help replace essential heart and souls that Mark may have lost due to sweating or from being exposed to the harsh elements of the dessert. If Henry, the paramedic, were to give Mark a drink that was lacking the right(a) ratio of electrolytes/glucose to water, he could risk exposing the cells in the body to a hypotonic state, in which the cells would burst, or a hypertonic solution in which the cells would lose even more fluid. (Mario)Question 3. Why DID Mark become disoriented? How would you test your ideas to see if you are right? What does your group think based on the reading in the text? Mark became disoriented because he was experiencing heat stroke. To see if I was right I would research the symptoms of heat stroke, and see if Mark had any of the symptoms. (Kassie)Que stion 4. What should Mark be concerned with regarding these moles? He talked to dermatologist, Dr. Charles Culp about the moles. What test might Dr.Culp conduct after removing the moles?Mark should be concerned that he has create malignant melanoma from his exposure to the sun without shaming sunscreen. If the dermatologist can tell for sure that the mole contains melanoma cells, special tests may be done to confirm their diagnosis. These tests that can be performed are called immunohistochemistry, fluorescence in situ hybridization, and comparative degree genomic hybridization. (Kassie)Final Set of Case Study QuestionsQuestion 1. Define the terms in the case battlefield high lightered in boldface. Heat stroke is the condition in which the skin becomes hot and dry as the body temperature continues to rise. Damage may be done too many organs, such as the brain, due to the lack of blood flow. First-degree burn is a burn that affects only the superficial skin/first layer Electrolyte s substance that ionizes in a water solution Glucose is a monosaccharide in blood that is the primary cum of cellular energy Melanin is darkpigment formed by cells called melanocytes (Kassie)Question 2. Assuming that Mark lost around 4 liters of water, what percentage of his body water did he lose? Would you expect his urinary chroma to decrease or increase during his trek? Please explain your answer.If Mark, weighing 77 kg (average manlike weight), were to lose 4 liters of water that would be around 10% of his total body water. In his keep and heat stroke state, Marks body would need to conserve water. I would expect Marks urinary volume to be decreased because he is dehydrated he isnt in taking any liquid for him to be voiding out. (Vanessa)Question 3. Why was Marks blood pressure so low? Would his pulse rate decrease or increase? Also wherefore was Mark whacky and disoriented? Please explain.Marks blood pressure was really low because he was very dehydrated. Also because he is dehydrated and not in taking any fluids his blood pressure will continue to lower because there is no blood volume for his body to dot his blood. Marks pulse rate will now increase, to try and raise his blood pressure to normal. Mark is dizzy and disoriented because he is dehydrated, and has a low blood pressure and pulse. Being earnestly dehydrated altered Marks brain and nerve function, making him feel very dizzy and disoriented. Also Marks low blood pressure and low pulse would make him feel dizzy because it is slowing the rate at which blood flows to his brain, lowering the levels of oxygen and making him feel light headed. (Vanessa)Question 4. Assume that Mark had an unopened six-pack of beer in his car. Would it have been a good idea for Mark to bring the beer along in case he got thirsty? Why or why not? Beer is known as a diuretic, which increases a persons overall urine output. It would have been a bad idea for Mark to drink an unopened six-pack of beer for many reaso ns. Because beer isnt water, it will eventually add to Marks dehydration by increasing his sodium levels and his urine output, both of which will make his cells in a furthered hypertonic state. This will also throw off Markselectrolyte imbalance, adding to his cells hypertonic state. (Vanessa)Question 5. What vitamin would Mark have in greater amounts in his body after that day and what role does the vitamin play in the body?After spending an extended period of time in the sun, with no protection from the suns UV rays, Mark would have a great amount of vitamin D built up in his body. Vitamin D can be absorbed from dietary supplements or few foods, it is naturally produced when the suns UVB rays reacts with cholesterol. Vitamin Ds main role is to promote calcium absorption, as well as aid in bone crop and remodeling. Vitamin D also regulates cell growth, neuromuscular and immune function, and reduces inflammation. (La)Question 6. What did Mark do that increased his receive of burns and what could he have done differently? Mark took his shirt off as the heat intensity rose throughout the day. This exposed his unprotected skin to the suns harsh UVA and UVB rays. not only was Mark not wearing any protection from the sun, but he also failed to wear sunscreen, which would have helped to shield his skin from the suns rays. If Mark had been wearing sunscreen or clothing to protect him from the sun, he may not have gotten such severe burns. (La)Question 7. Why would Marks skin have looked red within the first few hours of his adventure rather than lighting evolution hours and days later as a result of sunburn?Marks skin will see red within the first few hours of his adventure rather than redness developing hours and days later as a result of sunburn because of blood in the dermal vessels adds warp to the skin. When blood well oxygenated, the blood pigment hemoglobin is bright red, making the skin of light-complexioned people appear pinkish. (La)Works CitedShier, David, Jackie Butler, and Ricki Lewis.
