Question

12. Explain how hydrostatic pressure maintains fluid balance in the body. 13. Explain what is meant by isotonic, hypertonic, and hypotonic solutions and how, when each is administered, each controls fluid balance. 14. List the patient populations that are at risk for deficient fluid volume; populations that are at risk for over hydration?

Answer 1

12 Hydrostatic pressure is the pressure extered by intravascular fluid that is blood plasma or extravascular fluid on the wall blood vessel

13 ISOTONIC SOLUTION;Is one that has the same osmolality orsolute concentration as another solution if these two solution s are seperate by semipermable membrane water will flow in equal parts out of each solution and into the other. theis moving the both ways.it is using in the critical ill example acute kidndney injury and dehdration. example of isotonic solutions .9%normal saline and linger latacte

HYPERTONIC SOLUTION ;In aparticular type of solution that has greater concentraion of solute on the outside of cell whe compared with inside cell it used for the replacement of fluids this fluid is usually has 5%dextrose added most commomly used traumatic situation and large amound of fluid lost thruogh the alimentary tract

HYPOTONIC SOLUTION : when the concentration of the medium is less than the cell, the cell swells up i.e it gains  water this is known as hypotonic solution example is .45% normal saline

14 risk of FVD patients are: Patient with diarrhea, vomitting, sweating, adrenal insufficiency, nausea, burns and liver dysfunction

OVER HYDRATION : People who runs marathons and ultramarathons

ironman triathletes

endurance cyclists

rugby players

military members involed in training exercise
