The nurse is caring for a client with cirrhosis of the liver who has developed esophageal varices. The nurse understands that the best explanation for development of esophageal varices is which of the following? a. Chronic low serum protein levels result in inadequate tissue repair, allowing the esophageal wall to weaken. b. The enlarged liver presses on the diaphragm, which in turn presses on the esophageal wall, causing collapse of blood vessels into the esophageal lumen. c. Increased portal pressure causes some of the blood that normally circulates through the liver to be shunted to the esophageal vessels, increasing their pressure and causing varicosities. d. The enlarged liver displaces the esophagus toward the left, tearing the muscle layer of the esophageal blood vessels, which allows small aneurysms to form along the lower esophageal vessels. answer at no. 7 of : rnpedia/home/exams/nclex-exam/physiological-adaptation-nclex-rn-practice-test/answer-and-rationale
