Flashcard 3551: What acid-base disturbance is associated with the maintenance phase of acute tubular necrosis?_____

Answer: Metabolic acidosis

Flashcard 3552: What is the 2nd most common cause of dementia in the elderly? _____

Answer: Vascular dementia

Flashcard 3553: Syringomyelia typically results in pain/temperature deficits in the _____ extremity

Answer: upper

Flashcard 3554: What endocrine pathology is associated with UTI? _____

Answer: Diabetes mellitus

Flashcard 3555: Does a vascular function curve showing a **decrease** in mean systemic filling pressure (MSFP) reflect a patient with chronic anemia or anaphylaxis?

Answer: Anaphylaxis

Extra: Anaphylaxis causes venous dilation, which increases venous compliance and decreases the **mean systemic filling pressure (MSFP)**, shifting the x-intercept of the venous return curve to the left. In contrast, **chronic anemia** involves an increase in blood volume (increasing MSFP) and a decrease in blood viscosity (increasing the slope of the venous return and cardiac output curves).

Flashcard 3556: Diagnosis of sickle cell anemia is confirmed by hemoglobin _____

Answer: electrophoresis (test)

Flashcard 3557: What is the most common endogenous cause of Cushing syndrome?_____
