Gatrectomy is a procedure that involves removal of a part of the stomach (partial gastrectomy) or the whole stomach (total gastrectomy). It is carried out to removal stomach cancer or stomach perforations. In this case, the nurses initial action will be first not to tamper with fresh surgery tubes and then call the primary health care provider for blood draining from the NG tube after the procedure (gastrectomy)
Answer:
It helps to make scientific inquiries
Explanation:
Environmental science is a broad discipline which includes geology, physics, biology etc.
The nature of inquiries is often scientific. The procedures to follow in making useful deductions about environmental phenomenon must be guided scientifically.
Scientific methods is a systematic approach in which scientists can gather facts. Through their numerous observations, they formulate a sort of scientific guess called an hypothesis. Hypothesis can be tested over time and theory springs up. These theories can then be applied to tackle various related scientific puzzles.
The pH of solutions is an important chemical property. Oxygen is much more electronegative than hydrogen. Both shared electrons in an oxygen-to-hydrogen bond tend to spend more time with the oxygen atom than with hydrogen. Although the vast majority of water molecules remain intact in liquid water, at any given moment a few individual hydrogen atoms succumb to the pressure of the electronegative oxygen and lose their hold on both shared electrons. When this happens, the covalent bond is broken and a hydrogen ion<span> (positive charge because it lost its electron to oxygen, shorthand = H</span>+<span>) is released. The remaining part of the original water molecule is called a </span>hydroxide ion<span> (negative charge because it kept an extra electron, shorthand = OH</span>-). Although present at very low levels in solution, H+<span> and OH</span>-<span> ions can have enormous effects on the properties of a solution, especially when they are not in balance. In pure water, every hydroxide ion that forms creates a hydrogen ion, so there are equal numbers of anions and cations. If a solute is added to water, however, this balance can change.</span>
