A client has a patch test performed with the following results. Which of the following is the best response the nurse will offer the client regarding the observations from the test?

Choice A reason: This is the correct answer because portal hypertension means that there is high blood pressure in the portal vein, which carries blood from the digestive organs to the liver. When the liver is damaged by hepatitis, it becomes scarred and obstructs the blood flow, causing increased pressure in the portal vein. This leads to fluid accumulation in the abdomen, called ascites, which causes abdominal swelling.

Choice B reason: This is incorrect because portal hypertension is not caused by the heart overworking but by liver damage. The heart does not pump blood into the portal vein, but into the hepatic artery, which supplies oxygenated blood to the liver.

Choice C reason: This is incorrect because portal hypertension does not develop when cirrhosis begins to resolve, but when it progresses. Cirrhosis is a chronic condition that causes irreversible scarring of the liver tissue, which worsens over time and increases portal hypertension.

Choice D reason: This is incorrect because eating high-sodium foods and a stressful lifestyle do not cause portal hypertension, but they can aggravate it. High-sodium foods can increase fluid retention and worsen ascites, while stress can increase blood pressure and worsen bleeding complications. The nurse should advise the client to limit sodium intake and manage stress levels.

Choice A Reason: Measuring the abdominal girth is not related to asterixis, which is a tremor of the hand when the wrist is extended. It may indicate ascites, which is a complication of cirrhosis, but not asterixis.

Choice B Reason: This is the correct choice. Asterixis is a flapping tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings. It is caused by abnormal function of the diencephalic motor centers that regulate the muscles involved in maintaining posture. It is a sign of hepatic encephalopathy, which is a neuropsychiatric disorder that occurs in patients with liver disease.

Choice C Reason: Having the client flex and extend their foot is not related to asterixis, which affects the hand and wrist. It may test for ankle clonus, which is a rhythmic contraction of the calf muscles when the foot is dorsiflexed. It indicates an upper motor neuron lesion, but not hepatic encephalopathy.

Choice D Reason: Asking the client to walk heel to toe is not related to asterixis, which affects the hand and wrist. It may test for balance and coordination, which can be impaired in patients with hepatic encephalopathy, but it is not a specific sign of asterixis.
