When analyzing laboratory values, for a patient diagnosed with Graves' disease, the nurse would expect to find a

A. Diminished serum albumin levels cause water to shift from blood to tissue: In cirrhosis, liver dysfunction leads to decreased production of albumin, a protein that helps maintain oncotic pressure. Low albumin levels cause fluid to shift from the vascular space into the tissues, resulting in ascites and peripheral edema.

B. Portal hypotension causes a fluid shift from the abdominal cavity into the portal veins: Portal hypertension, not hypotension, is a common feature of cirrhosis, but it leads to ascites by increasing pressure in the portal venous system, not by shifting fluid into the portal veins.

C. Hypoaldosteronism causes a fluid volume deficit: shifting water from blood into tissue: Cirrhosis often leads to hyperaldosteronism, not hypoaldosteronism, resulting in sodium and water retention, which contributes to edema.

D. Aberrations of the portal system cause a back-up of blood that leads to hydronephrosis: Hydronephrosis is related to obstruction of the urinary tract, not a complication of portal hypertension or cirrhosis.

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.
