A decreased plasma oncotic pressure is caused by
A)loss of plasma proteins,such as albumin.
B)leukocytosis.
C)a hypoxemia-induced polycythemia.
D)dehydration and "tenting."

Question

Quizplus · Accepted Answer

Plasma oncotic pressure is determined by the concentration of plasma proteins, primarily albumin. Loss of plasma proteins, such as through burns, kidney disease, or malnutrition, can decrease oncotic pressure. Leukocytosis (B) is an increase in white blood cells and would not affect plasma oncotic pressure. Hypoxemia-induced polycythemia (C) is an increase in red blood cells due to low oxygen levels, also not directly related to oncotic pressure. Dehydration and "tenting" (D) can affect skin turgor but would not directly affect oncotic pressure.
