Med/surg Exam 2 Terms

Front 1

an acid-base inbalance characterized by an increase in H+ concentration (decreased pH). A low, arterial pH due to reduced bicarbonate concentration is called metabolic acidosis; a low arterial pH due to increased PCO2, is respiratory acidosis

Back 1

physiologic pump that moves fluid from an area of lower concentration to one of higher concentration, active trasport requires adenosine triphosphate (ATP) for energy

Front 2

an acid-base imbalance characterized by a reduction in H+ concentration (increased pH). A high arterial pH with increased bicarbonate concentration is called metabolic alkalosis, a high arterial pH due to reduced PCO2 is respiratory alkalosis

Back 2

the process by which solutes move from an area of higher concentration to one of lower concentration, does not require expenditure of energy

Front 3

a dynamiv process that involves the cessation of bleeding from an injured vessel, which requires activity of blood vessels, platelets, coagulation and fibrinolytic system

Back 3

maintenance of a constant internal equilibrium in a biological system that involves positive and negative feedback mechanisms

Front 4

the pressure crated by the weight of fluid against the wall that contains it. In the body, hydrostatic pressure in vlood vessels results from the weight of fluid itself and ther force resulting from cardiac contraction

Back 4

a solution with an osmolality higher than that or serum

Front 5

a solution with an osmolalitylower than that of serum

Back 5

a solution with the same osmolality as serum and other body fluids. Osmolality falls within normal range for serum (280-300 m/kg)

Front 6

the process by which fluid moves across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration; the process continues until the solute concentration are equal on both sides of the membrane

Back 6

the measurement of the osmotic pressure of a solution; another term for osmolality
