Explanation

Cirrhosis is the end-stage of chronic liver disease, characterized by irreversible scarring (fibrosis) and the formation of regenerative nodules.
It is a direct consequence of long-term, excessive alcohol consumption, which causes progressive inflammation and destruction of liver cells over many years.
While alcohol also causes fatty liver, cirrhosis represents the most severe and definitive outcome of chronic abuse, leading to significant loss of liver function.
Alcohol-associated cirrhosis accounts for approximately 48% of all deaths due to cirrhosis.

Option B: Cholestasis refers to the blockage of bile flow. While it can occur as a complication of severe alcoholic liver disease (like alcoholic hepatitis or cirrhosis), it is a resulting condition rather than the primary disease process itself.
Option C: Fatty liver (steatosis) is the earliest and most common stage of alcoholic liver disease. However, cirrhosis is the final, irreversible, and most severe stage, which is the classic outcome of long-term chronic abuse.
Option D: Hepatitis B is a viral infection of the liver caused by the Hepatitis B virus (HBV). It is transmitted through contact with infected blood or body fluids, not by alcohol consumption.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pathophysiology of Alcoholic Liver Disease as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in screening patients for alcohol use disorder and educating them about the risks of liver disease.
For patients with a history of chronic alcohol use, nurses must monitor for signs of liver decompensation, such as jaundice, ascites, edema, and changes in mental status (hepatic encephalopathy).
Promoting abstinence is the cornerstone of therapy. Nurses can provide support, resources, and referrals for substance abuse treatment.

How to Approach the Question

First, identify the key terms in the question: 'Chronic alcohol abuse' and 'causes'. This points to a long-term consequence.
Next, evaluate each option's relationship to alcohol abuse.
Recognize that Hepatitis B is viral and can be eliminated as an answer.
Differentiate between the remaining options (Cirrhosis, Cholestasis, Fatty liver) as they relate to alcohol.
Understand that alcohol causes a spectrum of liver disease. Fatty liver is the earliest stage, while cirrhosis is the end-stage.
Since the question specifies 'chronic' abuse, select the option that represents the most severe, long-term, and definitive outcome, which is cirrhosis.
