A patient presents to the emergency department (ED) complaining of nausea, vomiting, and the “worst headache he has ever experienced.”. While examining the patient, the nurse notes left leg and arm weakness.The patient is immediately sent to the radiology department for a CT scan. The registered nurse (RN) identifies the immediate need for treatment because:
A hemorrhagic brain attack is more common than an ischemic brain attack.
A thrombolytic drug will cause the peripheral and central reflexes to become hyper-reactive.
A hemorrhagic brain attack requires immediate intervention to prevent further damage.
An ischemic brain attack is less severe than a hemorrhagic brain attack.
The Correct Answer is C
Choice A rationale
A hemorrhagic brain attack (stroke) is less common than an ischemic brain attack. Ischemic strokes account for the majority of strokes.
Choice B rationale
Thrombolytic drugs are used to treat ischemic strokes, not hemorrhagic strokes. They do not cause hyper-reactive reflexes.
Choice C rationale
A hemorrhagic brain attack requires immediate intervention to prevent further damage. Hemorrhagic strokes involve bleeding in the brain, which can rapidly worsen and cause severe damage.
Choice D rationale
An ischemic brain attack is not necessarily less severe than a hemorrhagic brain attack. Both types of strokes are serious, but hemorrhagic strokes often require more urgent intervention due to the risk of ongoing bleeding.

Correct Answer is A
Explanation
Choice A rationale
Severe headache and photophobia are classic symptoms of meningitis, indicating inflammation of the meninges.
Choice B rationale
Chest pain and shortness of breath are more indicative of cardiovascular or respiratory issues, not meningitis.
Choice C rationale
Abdominal pain and diarrhea are gastrointestinal symptoms and are not typically associated with meningitis.
Choice D rationale
Joint pain and swelling are more indicative of rheumatologic conditions, not meningitis.
Correct Answer is A
Explanation
Choice A rationale
Elevated blood ammonia levels are a common consequence of liver dysfunction, particularly in conditions like cirrhosis and alcoholic liver disease. The liver is responsible for converting ammonia, a byproduct of protein metabolism, into urea, which is then excreted by the kidneys. When the liver is damaged, it cannot effectively perform this function, leading to elevated blood ammonia levels. High ammonia levels can cross the blood-brain barrier and cause hepatic encephalopathy, which manifests as confusion, memory loss, and asterixis (a flapping tremor of the hands). These neurological symptoms are consistent with the patient’s presentation.
Choice B rationale
An increased white blood cell count typically indicates an infection or inflammation. While infections can occur in patients with liver disease due to a compromised immune system, the symptoms described (increased blood glucose, blurred vision, memory loss, and asterixis) are more indicative of hepatic encephalopathy rather than an infection.
Choice C rationale
Elevated blood urea nitrogen (BUN) levels can occur in liver disease, but they are more commonly associated with kidney dysfunction. BUN is a measure of the amount of nitrogen in the blood that comes from the waste product urea. While liver dysfunction can affect BUN levels, the symptoms described are more specifically related to elevated ammonia levels and hepatic encephalopathy.
Choice D rationale
A decreased platelet count, or thrombocytopenia, is a common finding in liver disease due to splenic sequestration and decreased production of thrombopoietin. However, thrombocytopenia does not directly cause the neurological symptoms described in the patient. The symptoms of increased blood glucose, blurred vision, memory loss, and asterixis are more specifically related to elevated ammonia levels and hepatic encephalopathy.
