Explanation:
Answer:
In a patient underwent a single contrast upper GI series on Tuesday due to severe daily esophageal burning for six weeks, whose radiological diagnostic impression was Barrett's esophagus.
- <u><em>Day of encounter</em></u><em>: </em><em>Tuesday
</em>
- <u><em>Diagnosis Code</em></u><em>: K 22.7 </em><em>(CIE-10 code for Barrett's Esophagus)</em><em>
</em>
- <u><em>Procedure Code</em></u><em>: 74240</em>
Explanation:
Barrett's esophagus is a clinical condition characterized by a change in the esophageal epithelium due to repeated exposure to gastric juices, by reflux, or other mucosal irritants.
Corrosive agents are considered to produce a change in the epithelium called metaplasia, associated with symptoms of esophageal burning and pain.
The ICD-10 code for Barrett's esophagus is K 22.7.
The procedure, which consists of a radiological examination of the upper digestive tract with the use of barium contrast has a code of 74240, which describes this type of radiological examination.
Answer:
Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O
Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O
Explanation:
Dehydration
In chemistry, a dehydration reaction is one that involves the loss of water. In organic synthesis, where an acid is often used as a catalyst, there are numerous examples of dehydration reactions: Conversion of alcohols to ethers: 2 R-OH → R-O-R + H2O Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O Conversion of amides to nitriles: RCONH2 → R-CN + H2O
