FCCN 1 Exam Questions & Answers 100% Correct
Question : minimum urine output for adult
CORRECT ANSWER : 0.5mL/kg/hr
Question : ADH (antidiuretic hormone)
CORRECT ANSWER: - water retainer
vasoconstrictor (also called Vasopressin)
produced by hypothalamus
store and released from posterior pituitary
Question : ADH pathway
CORRECT ANSWER : - hypothalamus senses low blood
volumed and increased serum osmolality
signal pituitary to release ADH
ADH causes kidney to retain water
water retention increases blood volume and decreases serum osmolality
Question : ANP (atrial natriuretic peptide)
CORRECT ANSWER : - cardiac hormone stored in atria
released when atrial pressure increases *works opposite of RAAS by decreasing BP and reducing intravascular volume
important diagnostic marker in CHF
Question : hydrostatic pressure
CORRECT ANSWER : - forces fluids and solutes through
the capillary wall and into the tissue spaces
Question : colloid osmotic pressure
CORRECT ANSWER : - pulling force of albumin in the
intravascular spaces
pull fluid into vasculature
Question : maintenance fluid therapy
CORRECT ANSWER : - replaces normal ongoing losses of
water and electrolytes (urine, sweat, respiration, stool)
Question : replacement therapy
CORRECT ANSWER : - corrects any existing water and or
electrolyte deficits
Question : isotonic fluids
CORRECT ANSWER : - tonicity equal to plasma in the
body
no fluid shifts because the solutions are equally concentrated
LR
NS
D5W
Question : hypotonic fluids
CORRECT ANSWER : - lower concentration of solutes in
the vasculature than in the cell
fluid shifts into the cell to dilute the electrolytes (CELL
SWELLS)
0.45NS
Question : hypertonic fluid
CORRECT ANSWER : - higher concentration of solutes in
the vasculature than in the cell
