What would be the incorrect statement related to the fluid compartment of a human
Having more fatty mass than male leads to less representation of fluid in body mass of female
Total body water of a new born represent around 75% of total body mass.
Interstitial fluid represents 20% of extra cellular fluids
Each fluid compartment in human body are not completely separated from each other
Interstitial fluid does not includes;
synovial fluid
aqueous humor
blood plasma
cerebrospinal fluid
Which statement is correct regarding the barriers separating ICF and ECF
These barriers completely separate each fluid compartment
Plasma membrane serve as a semi-permeable barrier between ICF and ECF
Ion exchange via plasma membrane occurs due to passive transport mechanisms
A change in one fluid compartment affect the others
Functions of the electrolytes in human body includes;
control the osmosis of water between fluid compartments
serve as cofactors needed for optimal activity of enzymes
production of action potentials
All above are correct
Incorrect statement regarding body fluids is;
Na+ - K+ pumps plays a major role to maintain the ion balance in ECF and ICF
Having protein anions in the interstitial fluid is its major difference to blood plasma
In ICF, K+ is the main cation while proteins and PO42- are main anions
Apart from Cl- ions, HCO3- also identified in ECF
A patient comes to the hospital due to "Kaneru" poisoning. "Kaneru" poison usually increase the K+ concentration in body. What would be the possible outcome you have to pay attention as a nursing officer?
Severe thirsty
Dysfunction of the nervous system
Severe headache
Cardiac dysrythmia
Osmolarity of a NaCl solution is mentioned as 1 osm/L. What is the incorrect statement regarding this NaCl solution
This solution contains 0.5 moles of NaCl
One liter of this solution contains 1 moles of Na+ ions
One liter of this solution contains 0.5 moles of Cl- ions
This solution can be considered as a hypertonic solution
Which statement is correct regarding the osmolarity of different body fluid compartments
Osmolarity of blood plasma is little lower than ICF and interstitial fluid
About 50% of the osmolarity of ICF is due to Cl- ions
Osmolarity of ICF and interstitial fluid is kept equal by ion exchange activities through cell membrane
Osmolarity difference in plasma and interstitial fluid is due to HCO3- ions
A fish from the sea accidently come to a river and unable to go back to the sea. What would happen to this fish?
The fish will adapt to the river environment
Fish will die due to the shrinking of body cells
Fish will die due to changes in the oxygen concentration in river water
Fish will die due to the swelling of body cells
Water intoxication may happens due to large consumption of water in a shorter period of time or due to poor kidney function. What is the correct statement regarding this condition?
In this situation water act as a isotonic solution
Signs and symptoms of this condition will be vomiting, diarrhea and abdominal pain with fever
Swelling of the neurons will cause complications in water intoxication
In this situation osmosis of water from intercellular to extracellular occur
