Self Study Of Fluid Movement Flashcards
What happens to a patients ECF when given an infusion of Sodium chloride 0.9%
Volume will increase, osmolality will remain unchanged
when given an infusion of Sodium chloride 0.9% , What will happen to the osmolality of the ICF
Remain unchanged
Will water move from ICF compartment to ECF compartment when a patient is given an infusion of 1L sodium chloride 0.9%
No
What will happen to plasma protein conc and haematocrit when a patient is given an infusion of 1L sodium chloride 0.9%
Nothing
Will a patients RBCs be swollen when a patient is given an infusion of 1L sodium chloride 0.9%
No
What will happen to a patients arterial BP when a patient is given an infusion of 1L sodium chloride 0.9%
It will increase
What happens to ECF in a patient with severe diarrhoea
ECF volume decreases, osmolality increases, water shifts from ICF to ECF
What happens to plasma protein and haematocrit as a result of diarrhoea
Will increase
Will a patient with diarrhoea have swollen RBCs
No
What does severe diarrhoea do to bp
Decrease it
What happens to ECF in a man who consumed an XS amount of NaCl
ECF Volume increases, ECF osmolality increases, ICF osmolarity increases, water shifts from ICF to ECF
What is the major cation in sweat
Sodium
What happens to ECF as a result of 24 hours in desert with no water
Osmolality of ECF will have increased due to loss of fluid in sweat
Water will shift from ICF to ECF, osmolarity of ICF increases, volume of ICF decreases
Osmotic Properties of sweat
Hyperosmotic in comparison to plasma
Increased osmotic pressure as a greater amount of solutes in solution than plasma
what happens to ECF in a patient with SIADH
Osmolality of ECF will decrease due to increased retention of water
ICF and ECF volumes increase = Hyponatraemia
