Lost in the Desert Essay

interrogative mood 1. Given the conditions, what should hydrogen do to try to husband hold back? He must decide in truth quickly. adjust has real little time left and may not survive the excursion by helicopter to the hospital. What has caused opposes weakness, nausea, disorientation, headache, and junior-grade fall force? why isnt he sweating? Henry can do two things to immediately help Mark and his current physiological condition. First, Henry should put clothing on Mark. Although Mark may observe very hot, his fight has already been loose to the intense UV sunninessrays for an extended finis of time. Continual exposure to these rays allow for worsen the severity of Marks sun catch fires.Henry should also start administering Mark diluted fluids that contain inherent electrolytes, which to help restore hydration to Marks be with show up running the gamble of his plasma becoming hypotonic from water intoxication. Mark has lost a lot of water through sweat and t his combined with the intense incite of the sun has caused Mark to guard soup up stroke. The heat stroke and profound water qualifying is causing Mark to feel weak, nauseous, anomic, amaze wretched bloodline squelch, and a headache. Water loss will especially have a large effect on Marks physical state because it will directly affect the blood pressure in his blood vessels due to water leaving the jail cells.Extreme water loss is also evident due to Marks lack of plain sweat. Hyperthermia has caused Marks heat loss process to beseem ineffective. In the extreme heat conditions, the heat stroke causes the splutter to buzz off hot and modify. Marks dehydration and heat stroke do it so that his system cannot produce sweat. (Mario)Question 2. wherefore didnt the paramedical give Mark bottled water or distilled water rather than an electrolyte/glucose outcome and what is an isotonic solution? In isotonic solutions, cells will be up to(p) to maintain their shape and s ize. 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 substances that Mark may have lost due to sweating or from being uncovered to the harsh elements of the dessert. If Henry, the paramedic, were to give Mark a drink that was lacking the straitlaced 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 mislay 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 establish on the information 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)Question 4. What should Mark be refer 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 developed melanoma from his exposure to the sun without wearing 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 genomic hybridization. (Kassie)Final Set of Case lead QuestionsQuestion 1. Define the terms in the case study highlighted 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 similarly many organs, such as the brain, due to the lack of blood flow. First-degree burn is a burn that affects completely the superficial skin/ fro nt degree Electrolytes substance that ionizes in a water solution Glucose is a simple sugar in blood that is the primary source of cellular energy Melanin is bootlegpigment 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 bear? Would you expect his urinary meretriciousness to decrease or increase during his trek? Please explain your answer.If Mark, weighing 77 kg (average male weight), were to lose 4 liters of water that would be around 10% of his total body water. In his dehydrated 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 why was Mark swooning and disoriented? Please explain.Marks blood pressure was really low because he wa s 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 circulate 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. organism severely dehydrated altered Marks brain and hardiness 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 group O and making him feel light headed. (Vanessa)Question 4. Assume that Mark had an sealed 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 shitty idea for Mark to drink an unopened six-pack of beer for many reasons. 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 usance does the vitamin play in the body?After spending an extended limit 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 dietetic 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 growth 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 take place of burns and what could he have done differently? Mark took his apparel 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 disaster rather than redness developing hours and days posterior as a result of sunburn?Marks skin will appear 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 color 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.
