A. Occurs when you are physically and psychologically exhausted: An aura is a specific set of symptoms that precedes the headache, not related to exhaustion.

B. Occurs in the postdrome and causes you to feel sleepy and weak: The postdrome phase is after the headache, and an aura occurs before the headache.

C. Is a trigger such as a stressful event, that is the cause of the headache: An aura is not a trigger but rather a symptom experienced before the headache begins.

D. An aura is a warning, such as an unpleasant smell, before the headache begins: An aura is a neurological phenomenon that can include visual disturbances, unusual smells, or other sensory changes occurring before the onset of a migraine.

A. Hyperproteinemia and increased drug effect: In cirrhosis, hypoproteinemia (low protein levels) occurs due to decreased protein synthesis by the liver, and drug metabolism is often impaired, leading to increased drug effects, but hyperproteinemia is not a typical finding.

B. Hyperkalemia and fluid retention: While fluid retention is common due to hypoalbuminemia and portal hypertension, hyperkalemia is not a direct consequence of hepatocyte dysfunction.

C. Hypercortisolism and increased infection risk: Hypercortisolism is not typically associated with cirrhosis. However, increased infection risk is common due to compromised immune function.

D. An elevated blood glucose and ammonia level: In cirrhosis, the liver's ability to metabolize ammonia is impaired, leading to elevated levels. Additionally, impaired glucose metabolism can result in hyperglycemia.
