Questions:

1. Classify this type of heat injury and explain why Mark has stopped sweating.

Heat stroke - results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. The medical definition of heat stroke is a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma.

2. Based on your diagnosis in #1, what immediate treatment would you provide for Mark?

Fanned air over the patient while wetting his or her skin with water maybe from an IV bag or anything available. Apply ice packs to the patient's armpits, groin, neck, and back. Because these areas are rich with blood vessels close to the skin, cooling them may reduce body temperature.

3. What specifically caused Mark’s weakness, nausea, disorientation, headache, and low blood pressure?

Prolonged exposure to high temperatures and dehydration. This leads to failure of the body's temperature control system. (Hypothalamus)

4. Since you have lost contact with the Hospital, you are not authorized to start an IV and you need to re-hydrate the patient. On board the helicopter is a 4-liter container of bottled water, 4 quarts of Gator-Ade, and 2 2-liter bottles of coke. Describe each of these drinks in terms of isotonic, hypertonic and/or hypotonic and then explain which one you would give to Mark to drink and why?

Pure water is hypotonic, coke is hypertonic, Gatorade is isotonic
I’d give Mark Gatorade an isotonic drink contains the same concentration of salts as human blood and body cells therefore

Lost in Desert

...1. When the body depletes its salt and water supplies, sweating stops and heat loss by evaporation of sweat is blocked. 2. Mark has lost a great deal of his electrolytes through sweating earlier in the day containing sodium, potassium, calcium, chloride and bicarbonate. All aid in the ability for the body to maintain homeostasis and muscle control. 3. During a heat stroke, your body is unable to properly cool itself. When it is unable to cool itself, the core body temperature rises rapidly.When the core temperature rises, the brain begins to fail. (The brain can only function in a very narrow temperature range). As the brain overheats, the individual will become disoriented, combative, argumentative and may hallucinate. 4. Due to the growth, change of color and bleeding these are all first signs of melanoma. He should have them looked at by the dermatologist. The Dr. will more than likely take a biopsy of the mole. All potentially cancerous skin growths must be biopsied to confirm acancer diagnosis. Depending on the suspected type of skin cancer, the biopsy techniques vary slightly but crucially. Any potential melanoma requires a surgical biopsy, in which the entire growth is removed with a scalpel if possible. A pathologist then studies the sample under a microscope to determine whether cancer cells are present. If melanoma is diagnosed, other tests may be ordered to assess the degree of cancer spread (metastasis). They include: Imaging. Your doctor will order one...

The Lost Tribe

...The Lost Tribe of Antiquity An explorer named Abel Cookman had finished his adventure and discovered a lost ancient tribe which he called ‘Antiquity’. He felt amazed by the language of this tribe, and so he made a lot of notes about this lost civilization. Unfortunately, he died, but he left the notes for an investigation of this mysterious tribe. This essay will discuss the geography and location, family, political, economic and trade and culture of Antiquity. Geography and location In the notes, Abel mentioned three dominant geographical terms, designating ‘undulating hills’, ‘dry river bed’, ‘expansive sand dunes’. However, there were no words for ‘snow’ and ‘ice’. What’s more, ‘no terms for fish, pork or veal.’ It suggests that the tribe might have been located in the desert. There are lots of sand dunes in the desert and they might be unable to see the end of the desert. In addition, he mentioned that there were no words for ‘ocean’, but several for fresh water were ‘spring’, ‘oasis’ and ‘water hole’. They didn’t have ‘ocean’ in their language. So, it is likely that they had never seen the ocean. The word ‘water diviner’ stood for praise, therefore it is possible this person would be respected by the people of the tribe as they could find water. Also, palm trees appeared in the notes. Palm trees usually live in a desert and they are important plants and fruits in sub-tropical and arid regions. What’s more, ‘camel’, ‘rat’, ‘goat’, ‘heat’ and ‘dryness’ appeared in the...

Desert Trip 2014

... the participants of Duke of Edinburgh, I being one of them, were sent to Thumamah Desert located on the outskirts of Riyadh, Saudi Arabia. The purpose of Duke of Edinburgh is to give students a taste of how it feels like to live in nature and away from the modern world. Experiencing the climb of sharp and hilly mountains, learning how to use a GPS and how to calculate bearings as well as timings. Duke of Edinburgh was a wonderful experience for me, it also gave me a good excuse to spend two days with my friends! A desert is a massive land where little precipitation occurs and living conditions are hostile for plant and animal life. A desert is formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces. Our aim, as the group, was to find out how fossils were produced in the desert. After doing a lot of research and exploring, we came up with a conclusion that these desert fossils were produced a very, very long time ago when the ground was covered with sea. As years went by, water dissolved leaving all the plants and sea shells behind as well as the seabed. This then turned into desert and all the sea shells turned into fossils. There is evidence that this desert was covered by sea because when we were walking, we observed wave strokes on sand and in some parts the sand was weaker than others. A desert is packed with adventures and obstacles for people to challenge. Our group had experienced...

Colorado Water Supply Issues

...The problem is that there are millions of people living in an area that it is difficult to live because of the desert climate and lack of water. The Colorado River is drying up because there is a major drought going on in the southwest. Residents and business are using the Colorado River and aquifers unsustainably. The area has lost million of gallons of water that cannot be replaced. The future for the southwest depends on a way to secure a reliable water supply for the future. The dryer climate will produce more wildfire in the southwest. The droughts are expected to become hotter and more severe. The things that can be done to improve the conditions in the southwest are farther documenting water usage. There needs to be a way to be able to budget the water usage. Water recycling plants and desolation plants need to be built to reuse and produce more water. Lastly people need to remove plants that do not belong in desert climates and stop using water on unessential things. People need to become aware that the issue on water shortage is more realistic than led to believe. The problems that surround this limiting resource are practically unknown to the general population of the United States. America needs to help come up with a solution to these problems...

My Voyage to the Mojave Desert

...My journey began early monday morning around 7:00 A.M. at my sisters' house, Sara, in the coastal city of Newport Beach, California. Along with her was her husband, Jeremy, their two sons Sklyer and Logan, and myself. We were packing our belonging into their new vehicle to prepare for a trip to Jeremys' parents' house in the Mojave Desert. As we began to drive away i noticed all the lush green grass, the palm trees that seemed as tall as any building, and all the people outside carring on their lives. Then i glazed at the sparkling water in the ocean and thought how difficult it must be to live in desert conditions. Residents of the Mojave desert must live a more resislient life than most. We started out in bumper to bumper traffic on the highway. Hearing the sounds of car horns and motorists passing by i decided to play a movie to kill some time on our long voyage. It was shortly after the movie ended that we entered Barstow, California. The last source of gas and civilization for the next 40 miles. I gazed around noticing that this is the begining of the desert with a lack of plant life except for small patches of weeds and cactus. And i wondered what kind of place are we going to that is this sucluded from society. Skyler and Logan asleep from being bored from constantly watching nothing but miles and miles of sand, stone, cactus, and brushes, are awoken when we came upon a borax mine museum next to the actual mining pits that are still being used to this day...
