Answer: Steam burns the skin worse than hot water because the heat of vaporization is released as well.

Explanation:

The steam exhibit more energy than water at the same temperature that is 100° C. The steam uses the latent heat of vaporization so as to get vapourize and water do not exhibit energy. This latent heat of energy causes severe burns due to steam as compared to water.  Steam burns are caused by the heat of vapors and they form scalds.

What are the functions, bacteria, enzymes, and hormonal activities<br> of the GI tract?
masya89 [10]

Answer:

The answer to these multiple questions is pretty broad and long because the GI tract is probably one of the most diverse, complex, and function-filled systems of the human body.

1. To begin with, the GI tract has a main purpose, which is to ingest, digest, process, absorb and excrete the unnecessary waste that comes from the processes mentioned before. All of these have to do with fulfilling the main function of the GI tract, which is, to provide nutrients to the body through food and fluid intake. In order to fulfill this purpose, the tract is packed with muscles, accessory organs, blood vessels, nerve terminals and innervation and lymphatic vessels that willl aid in this process.

2. During the passage of food through the system there are a series of chemical steps that need to be taken, in order to be able to substract the necessary nutrients from food. In order to do this, the body counts with enzymes, chemical proteinic substances produced by different GI organs to ensure proper digestion and absorption of nutrients. Among the ones that we have are: amylase, pepsin, tripsin, pancreatic lipase, deoxyribonuclease and ribonuclease. All of these work on different molecules in food, like fats and carbs, and will allow the body to use them.

3. The GI tract also has hormonal activities, mostly related with the correct functioning of the entire system when food is present and nutrition is a must. Some of the enteroendocrine hormones are: gastrin, cholesystokinin and secretin, only to mention some.

4. The bacteria that populates our GI tracts are known as enterobacteria, they are mostly gram negative bacteria, like E. Coli, whose function is to further aid in the extraction and digestion of nutrients in food, once the chyme reaches the large intestine. These bacteria are from the enterobacteriaceae family and comprise more than 200 species.

Which nursing action has the highest priority for a teenager admitted with burns to 45% of the body?
juin [17]

Answer:

<em>Maintain aseptic technique.</em>

Explanation:

Aseptic techniques involves following the practices and procedures that prevents or reduces contamination by pathogens. A burn patient can have his protective upper skin layer removed, exposing the vulnerable inner skin layer. The inner skin layer is susceptible to infection, and if infected, can lead to further medical complication, which might even end up fatal.<em> Aseptic technique involves the use of barrier to minimize contact between the patient and the medical personnel. Such barriers includes sterile gloves , sterile gowns , masks for the patient and healthcare personnel, and  sterile drapes . Sterile barriers should not have touched contaminated surface, and should be prepacked and sealed. Medical instruments should be sterilized too.</em>
