A client arrives at the emergency room with symptoms of peptic ulcer disease. Which of these symptoms should the nurse identify as the priority?

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.

Choice A reason:Lactulose is used in hepatic encephalopathy primarily to lower blood ammonia levels. It works by converting ammonia in the intestines into ammonium, which is then excreted³. Therefore, a decrease in ammonia levels would indicate the effectiveness of the medication.

Choice B reason:While lactulose can relieve constipation due to its laxative effect, relief of constipation is not the primary indicator of its effectiveness in treating hepatic encephalopathy³.

Choice C reason:Decreased liver enzymes are not a direct measure of lactulose's effectiveness in hepatic encephalopathy. Liver enzymes are indicators of liver function, not ammonia levels³.

Choice D reason:Relief of abdominal pain is not a specific indicator of lactulose's effectiveness in hepatic encephalopathy. The medication's primary role is to reduce ammonia levels, not to alleviate pain³.
