A nurse is caring for a client who has cirrhosis and a prothrombin time of 30 seconds. Which of the following medications should the nurse plan to administer?
Warfarin
Vitamin K
Heparin
Ferrous sulfate
The Correct Answer is B
A. Warfarin:
Warfarin is an anticoagulant that works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X. While it is used to prevent thromboembolic events, in a client with cirrhosis and an elevated PT, the priority is addressing the coagulation factor deficiency rather than adding an anticoagulant.
B. Vitamin K:
Vitamin K is the antidote for warfarin, and it helps in the synthesis of clotting factors. In cirrhosis, there can be impaired synthesis of clotting factors due to liver dysfunction. Administering vitamin K can aid in correcting coagulation abnormalities.
C. Heparin:
Heparin is another anticoagulant, but it does not reverse the effects of warfarin. It works by a different mechanism and is typically used in acute settings, such as deep vein thrombosis or pulmonary embolism. It is not the primary intervention for an elevated PT in cirrhosis.
D. Ferrous sulfate:
Ferrous sulfate is an iron supplement and is not indicated for the correction of an elevated PT. Iron supplements are typically used to address iron deficiency anemia.

Explanation
A. Obstruction of the bile duct:
Biliary cirrhosis can result from chronic obstruction of the bile ducts, leading to damage to the liver tissue. This obstruction can be due to various causes, such as gallstones or strictures.
B. Hepatotoxic medications:
While certain medications can contribute to liver damage, biliary cirrhosis specifically refers to conditions affecting the bile ducts. Hepatotoxic medications may contribute to cirrhosis but not necessarily biliary cirrhosis.
C. Hepatitis C:
Hepatitis C is a viral infection that primarily affects the liver. While chronic hepatitis C infection can lead to cirrhosis, it is not synonymous with biliary cirrhosis.
D. Excessive alcohol consumption:
Excessive alcohol consumption is a common cause of cirrhosis, but biliary cirrhosis specifically refers to cirrhosis resulting from chronic obstruction of the bile ducts.
Correct Answer is B
Explanation
A. Atorvastatin: Atorvastatin is a statin medication used to lower cholesterol levels. It is not known to cause glucose intolerance.
B. Prednisone: Prednisone is a corticosteroid and can cause glucose intolerance by increasing blood glucose levels. Corticosteroids can lead to insulin resistance, impaired glucose utilization, and increased gluconeogenesis.
C. Ranitidine: Ranitidine is an H2 receptor antagonist used to reduce stomach acid production. It is not known to cause glucose intolerance.
D. Guaifenesin: Guaifenesin is an expectorant used to help loosen mucus in the airways. It is not known to cause glucose intolerance.
