Excellent! Your brain remembers something better when it is linked with place,time or emotion. Your way of explaining is funny and really transmissible so I keep the information in mind! Keep up the good work!

[@MedicosisPerfectionalis]

Thank you 😊

QUIZ TIME ANS: RBCs will swell and burst. Because The plasma is less concentrated than the RBC because it's been diluted, so water will move into the RBC causing it to swell and eventually it'll burst.

[@docgirl13]

100 cc will hardly make a difference in 5 Liters of Blood!

[@nikhilsimha9701]

​@@docgirl13may be But theoretically speaking.

[@tony___3077]

a nemonic I use to remember what will happen is that because of osmosis, the water will enter the RBCs and make them swell and burst; the RBCs get big and fat like circle, or O's. hypotonic has an O. So, any solution that makes RBCs swell and lyse would be a hypOtonic solution, or a question could say you are making the serum more hypOtonic. RBCs placed in a hypotonic environment will swell. HypErtonic solution (more than .9% saline) should have more solutes relative to blood and would cause RBCs to shrivel since water will be pulled out of them.

[@hannroseen9546]

@@shaima3997 my speech is the correct one

[@Android982]

While B would be correct if this patient is a test tube; but assuming the pt is a human with intact compensatory mechanisms, the pt would at least eliminate some of the fluid along with some Na+ and therefore the total body Na+ would decrease.

[@coolg887]

Thank you so much for explaining well these two confusing concepts. However, at 1:07, in the second question, you used "osmolality" with unit "/L." Should it be termed "osmolarity"? Thank you for your clarification in advance!

[@yahyasajid5113]

Exactly what I was thinking, silly mistake considering the emphasis on the pnemonic

[@minahm4633]

The answer of the question is "a" right?

[@mihaigherman3713]

In the quiz time part, why do you measure osmolaLity in /L? Shouldn't it be in /kg, as per your explanations further down in the video? What am I missing?

[@alexsheremett3097]

I also just saw it / but it doesn't change the situation , for 1 kg SORRY of blood should +/- equal 1 L of blood anyway errare humanum est

but there's also a "Rrrrrrrrrr" in Kilogrrrrrrrrrrrrram ?

What is the answer a or b I need to know

[@IzzyHur]

So you said Osmolarity is Liter and Osmolality is Kg.... how come you keep saying Osmolality of plasma is 290 mOsm/L? if its osmolality shouldnt it be Kg?

[@MedicosisPerfectionalis]

You're right. It should be plasma osmolarity = 290 mOsm/L. But clinically, it doesn't matter.

[@naranmajhi5105]

@@MedicosisPerfectionalis why? please help.

[@Zainabz005]

I know the right answer is B but could someone explain why wouldnt the Na concentration decrease too?

[@mohamedimzeer2238]

Your second question is wrong, u should ask the question like whats the osmolarity? Bcz units in L

[@MedicosisPerfectionalis]

It is true though, i was like what is cc (first time hearing it) .in my country we simply use the cm power of 3.

it doesnt ionize in solution. it just dissolves. so its 1 osmole

Why?

Bcz water is permeable it easily diffuses from ECF to ICF and results in cell swollen hence usually NS/DNS will be used for iv drips coz Na is impermeable

[@naranmajhi5105]

@@manju7062 NS and DNS is used as iv drips to replace lost ECF because these are isotonic solution.. they don't cause shift of water across ICF and ECF .. they only increase the ECF volume.
