how does osmolality affect fluid movement? Correct Answer: hypotonic fluid has little solutes, intracellular has a lot fluid tries to balance concentration moves into cells cell swells hypertonic fluid has lots of solutes, intracellular few fluid tries to balance concentration moves out of cells cell shrinks isotonic fluid and intracellular space are balanced cell remains the same we typically use _____tonic fluids for fluid replacement Correct Answer: isotonic indications for using hypertonic vs hypotonic fluids Correct Answer: hypertonic severe dehydration severe electrolyte imbalance severe hyponatremia hypotonic dehydration hypotonic DKA hyperosmolar hyperglycemia hypertonic dehydration what is the difference between osmolarity and osmolality? Correct Answer: osmolarity measures solutes in a liter (by volume) such as in a bag of fluid osmolality measures solutes in a kilogram (by weight) such as in your body which body systems help to regulate fluid and electrolyte balance? Correct Answer: renal system kidneys are primary organ to regulate endocrine system RAAS ADH natriuretic peptides respiratory system breathing out humidity can hypo/hyper ventilate as needed what are insensible losses? Correct Answer: fluid lost that isn't easily measured Examples: skin - sweat lungs - humidity of breath
