The nurse assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?
Explanation & Rationale
Choice A rationale While the renin-angiotensin response can be affected in cirrhosis, it is not the primary mechanism contributing to edema and ascites. In cirrhosis, there can be a decrease in renal blood flow which can lead to activation of the renin-angiotensin system, but this is not the main cause of fluid accumulation. Choice B rationale Hypoalbuminemia, or low levels of albumin in the blood, is a common occurrence in cirrhosis. Albumin is a protein that helps maintain oncotic pressure, which keeps fluid in the blood vessels. When albumin levels are low, fluid can leak out of the blood vessels and accumulate in the abdomen (ascites) and in the tissues, causing edema. Choice C rationale Hyperaldosteronism can occur in cirrhosis and can contribute to fluid retention. However, it is not the primary mechanism leading to edema and ascites. Aldosterone promotes sodium and water reabsorption in the kidneys, which can contribute to fluid retention, but this is usually a secondary response to other changes in the body. Choice D rationale Decreased portacaval pressure with greater collateral circulation is not the primary mechanism contributing to edema and ascites in cirrhosis. While portal hypertension is a common complication of cirrhosis, it is not directly responsible for the development of edema and ascites.
