The nurse understands that administering a hypertonic solution to a patient will shift water from the _____ to the _____ space
a. Intracellular; extracellular
b. Extracellular; intracellular
c. Intravascular; intracellular
d. Intravascular; interstitial
A
A hypertonic solution has a concentration greater than normal body fluids, so water will shift out of cells because of the osmotic pull of the extra particles. Movement of water into cells occurs when hypotonic fluids are administered. Distribution of fluid between intravascular and interstitial spaces occurs by filtration, the net sum of hydrostatic and osmotic pressures.
