FCCN LEVEL 1 EXAM UPDATED ACTUAL

EXAM WITH CORRECT SOLUTIONS.

minimum urine output for adult - correct answer- 0.5mL/kg/hr

ADH (antidiuretic hormone) - correct answer- - water retainer

• vasoconstrictor (also called Vasopressin)
• produced by hypothalamus
• store and released from posterior pituitary

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

ANP (atrial natriuretic peptide) - correct answer- - cardiac hormone stored in atria 1 / 4

• | Page

• released when atrial pressure increases

*works opposite of RAAS by decreasing BP and reducing intravascular volume

• important diagnostic marker in CHF

hydrostatic pressure - correct answer- - forces fluids and solutes through the capillary wall and into the tissue spaces

colloid osmotic pressure - correct answer- - pulling force of albumin in the intravascular spaces

• pull fluid into vasculature

maintenance fluid therapy - correct answer- - replaces normal ongoing losses of water and electrolytes (urine, sweat, respiration, stool)

replacement therapy - correct answer- - corrects any existing water and or electrolyte deficits

• / 4

isotonic fluids - correct answer- - tonicity equal to plasma in the body

• no fluid shifts because the solutions are equally concentrated

• LR
• NS
• D5W

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

hypertonic fluid - correct answer- - higher concentration of solutes in the vasculature than in the cell

• pulls fluid out of cells and into the vessels (CELL SHRINKS)

- D5 .45NS

- D5NS

- D5LR

• 3%, 7%, 23.4% NaCl
• / 4

colloids - correct answer- - pull fluid into bloodstream

Albumin

• 5% is osmotically equal to plasma
• 25% draws 4 times the normal volume into the circulation

blood - correct answer- - not a risk free fluid replacement

• this is liquid transplant

third spacing - correct answer- - fluid is not lost from the body but the fluid is not available for use in the intracellular or extracellular compartments (fluid is in between tissues/cells)

• this patient is intravascularly dry and still needs more fluid

-

can you give platelets through the ranger - correct answer- - no it will aggreggate the platelets

hyponatremia - correct answer- - less than 135 -145
