A client with advanced cirrhosis has been admitted to the medical-surgical unit. The nurse is assessing the client and identifies which of the following findings as indicators of hepatic encephalopathy? (Select all that apply).
Asterixis
Change in orientation
Anorexia
Ascites
Fetor hepaticus
Correct Answer : A,B,E
Choice A reason: Asterixis, also known as "liver flap," is a tremor of the hand when the wrist is extended, often seen in hepatic encephalopathy as a result of altered brain function.
Choice B reason: A change in orientation, including confusion and altered consciousness, is a hallmark of hepatic encephalopathy, reflecting the brain's impaired ability to process information.
Choice C reason: Anorexia may be present in cirrhosis, but it is not a specific indicator of hepatic encephalopathy.
Choice D reason: Ascites is a common complication of cirrhosis due to portal hypertension but is not a direct indicator of hepatic encephalopathy.
Choice E reason: Fetor hepaticus, a musty odor of the breath, is a distinctive symptom of hepatic encephalopathy caused by the presence of mercaptans in the breath as the liver fails to break down sulfur-containing amino acids.

Correct Answer is B
Explanation
Choice A reason: A heart murmur is not a common finding in right-sided heart failure unless there is an associated valvular heart disease.
Choice B reason: Dependent edema is a classic sign of right-sided heart failure due to the accumulation of fluid in the tissues, particularly in the lower extremities.
Choice C reason: Chest pain is more commonly associated with left-sided heart failure or other cardiac conditions such as angina.
Choice D reason: Crackles in the lungs are typically found in left-sided heart failure due to pulmonary congestion, not right-sided heart failure.
Correct Answer is A
Explanation
Choice A reason: A distended bladder is a common cause of autonomic dysreflexia. It can trigger an exaggerated response from the autonomic nervous system, leading to a rapid increase in blood pressure. This is because the full bladder sends signals to the spinal cord, which then attempts to send signals to the brain. However, due to the injury, these signals cannot pass through, resulting in a reflex that increases blood pressure.
Choice B reason: While a severe headache is a symptom of autonomic dysreflexia, it is not a cause. The headache results from the body's response to a triggering stimulus, such as a distended bladder, which leads to the high blood pressure characteristic of autonomic dysreflexia.
Choice C reason: Nasal congestion is not typically a cause of autonomic dysreflexia. The condition is usually triggered by a noxious stimulus below the level of the spinal cord injury, such as a full bladder or bowel, skin irritation, or other types of physical discomfort.
Choice D reason: Elevated blood pressure is a symptom, not a cause, of autonomic dysreflexia. The condition itself causes a sudden spike in blood pressure due to an uncontrolled reflex sympathetic discharge in response to a triggering stimulus below the level of the injury.
