nurse is concerned that he may need to receive oxygen. 3. To determine the need for the application of a nasal cannula‚ which assessment is most important for the nurse to perform? A. Measure oxygen saturation B. Auscultate breathing sounds C. Measure capillary refill D. Observe chest excursion A. Measure oxygen saturation - Rationale: Oxygen saturation provides important data about the percentage of hemoglobin that is saturated with oxygen - a valuable reflection of the client’s overall

1 CHAPTER 1 PROJECT BACKGROUND 1.0 PROJECT BACKGROUND The main objective is to design an economic Acrylonitrile chemical plant with safer ways of processes for a minimum production rate of 100‚ 000 metric tonnes/year. 1.1 INTRODUCTION Recently‚ production of acrylonitrile has been increasing every year in many countries. The rapid growth of the industry is mainly attributed to the availability of oil and gas as feedstock‚ a well-developed infrastructure‚ and a strong base

diseases. Acid rain deposits nitrates that can lead to increases in nitrogen in forests. Nitrogen is an important plant nutrient‚ but some forest systems may not be able to use all they receive‚ leading to nitrogen saturation. In the Eastern United States‚ there is evidence of nitrogen saturation in some forests. Nitrates can remove additional calcium and magnesium from the soils. Continued nitrogen deposition may alter other aspects of the nutrient balance in sensitive forest ecosystems and alter the

blood circulates around the body‚ collects oxygen‚ delivers the oxygen to the organs that require it and releases carbon dioxide. oxygen and carbon dioxide enter and exit the body in opposite directions across a respiratory surface area that supplies enough oxygen to allow the process to occur efficiently. The process begins when gases from the atmosphere‚ including oxygen‚ enter the body through either the nasal cavity‚ or the oral cavity. Afterwards‚ the oxygen enters the pharynx‚ a path that connects

work properly. Overview The gas exchange system is the process in which oxygen enters the cells of many living animals. Some factors that affect how efficient a gas exchange system is are things such as the distance that the molecules have to go before the oxygen enters the cells of the animal. The gas exchange system has to be moist in order for the process of diffusion to take place. When an animal needs to replenish oxygen it has to absorb it across tiny cell membranes deep in their gas

What is collagen? Collagen is a simple protein made up of amino-acids. Amino acids are built from carbon‚ oxygen and hydrogen. In fact collagen makes up approximately 30% of the protein within the body. As a structure Collagen is intensely strong and is a vital protein that is found all over the body: In tendons and ligaments. It plays an important role in the protection function of the skin in that it helps limit the absorption and spreading of pathogenic substances‚ environmental toxins‚ micro

temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one that is not too

D1 – Analyse how two body systems interrelate to perform named functions The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by

Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic
