question
A client with advanced cirrhosis has a prothrombin time (PT) of 15 seconds, compared with a control time of 11 seconds. The nurse expects to administer:
answer
phytonadione (Mephyton). Explanation: Prothrombin synthesis in the liver requires vitamin K. In cirrhosis, vitamin K is lacking, precluding prothrombin synthesis and, in turn, increasing the client's PT. An increased PT, which indicates clotting time, increases the risk of bleeding. Therefore, the nurse should expect to administer phytonadione (vitamin K1) to promote prothrombin synthesis.

question
A group of students is reviewing information about the liver and associated disorders. The group demonstrates understanding of the information when they identify which of the following as a primary function of the liver?
answer

question
client with cirrhosis has been referred to hospice care. Assessment data reveal a need to discuss nutrition with the client. What is the nurse's priority intervention?

Discuss meals that include low-fat high-carbohydrate content.

The nurse should limit the client's fat intake to prevent satiation and should restrict protein intake because a cirrhotic liver can't metabolize protein effectively.
