"Fluid in the tissue space between and around cells" is the appropriate nursing response.
Step-by-step explanation:
The intracellular fluid or fluid inside cells represents the greatest proportion of water in the body. The remaining body fluid is extracellular fluid or fluid outside cells. Extracellular fluid is further subdivided into interstitial fluid or the fluid in the tissue space between and around cells and intravascular fluid which is the watery plasma, or serum, portion of blood.
