Unit HSC 2024 –Undertake agreed pressure area care 1.1 Pressure sores or decubitus ulcers are the result of a constant deficiency of blood to the tissues over a bony area such as a heel which may have been in contact with a bed or a splint over an extended period of time. The surface of the skin can ulcerate which may become infected. Eventually deeper tissues are damaged. Besides the heel‚ other areas commonly involved are the skin over the buttocks‚ sacrum‚ ankles hips and other bony sites of

Thesis Statement: Water pollution is bringing down the economy‚ destroys the beauty of nature‚ and causing harmful dreaded diseases and sickness in precious health of many individual. INTRODUCTION Water pollution progresses every day in our lakes‚ oceans‚ rivers‚ and other bodies of water that we see and use in many ways. Water is essential for all living things to survive‚ yet people still pollute it. It’s pretty sad to be taking a trip to the beach with your family and you get there to see

and Effects of Water Pollution Image source: NASA Water covers 70% of the Earth’s surface and makes up over 60% of the human body. Water pollution affects marine ecosystems‚ wildlife health‚ and human well-being. The answer to solving pollution is to make changes in our daily habits and pay more attention to the types of products we consume. The following lists display causes of water pollution and the effects it has on human health and the natural environment. Causes of Water Pollution

how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

water exists in liquid‚ solid‚ and gaseous states water referred to universal solvent ( bipolar molecule enables it to dissolve a wide variety of substances) ice floats ( temperatures drop molecules come together as a solid‚ elections repell (the molecules get less close thus making the ice have less density than water. If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps

Introduction: Water is an essential living source for us humans and has a big impact on our everyday lives‚ thus people should be very concerned about what is actually in our tap water that we drink from everyday. The fluoride in the water can either occur naturally or by adding fluorine‚ by drinking a certain amount of fluoridated water each day can help to prevent tooth decay; the fluoridated water works on the surfaces of our teeth and causes the fluoride level in our saliva and hence reduces

Water Management Describe Water Management and Use Ground water and surface water make up freshwater sources in the form of streams‚ rivers‚ and wells. Freshwater sources are becoming depleted. We are facing a growing global water shortage due to precipitation‚ runoff patterns‚ droughts‚ and ground water withdrawals. Water conservation is protecting the quantity and quality of the water resources‚ with expectations to reduce the total amount of water being used for various purposes. Water
