Dear Friends, PLEASE take care with NS and Hypertonic saline in Hyponatremia. Correcting too fast can cause Central Pontine Myelinolysis (brain damage). When in doubt, ask the Nephrologist. Also, get your urine and serum lytes done BEFORE hydrating the pt - so you can figure out why the HypoNa. Thanks for the video, Your Friendly Neighborhood FP Attending :))

Thank @iMedicalSchool, that helps a lot.

I'm a fresh nursing grad and I intend to take up Medicine, this is very helpful, thank you!

I'm in Nursing school and found this very helpful. Thanks

This was great! Thank you!!

Thanks man, made it clear. always get confuse on those.

Solid Quick Review

I'm actually a nursing student but This video is extremely helpful!Thank you!!Just subscribed!!

i am a pharmacy tech student and this is very important for me to understand because i will be making ivs in the pharmacy where i am doing my extern in a few days.

Best video I have seen

great video by the way, I subscribed!

Are you sure Na+ move through a semi-permeable membrane in the absence of ion transporter?

@andrewdunn777

I agree. It is only water moving from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane. Na+ does not move

thank you so much for your video

my guy is saying straight faxX, keep it up broda

well my next rotations are in ob/gyn and peds but from the rotations so far i have had difficulty w/ different types of hyponatremia (euvolumic, hypo/hyper etc) and how to do a work up/ management. also work up for breast cancer, staging and management. Those are the ones i can think right off the top of my head

thank you

Nurses thank you! =) Subscribing ~

Nice .. My knowledge has expanded..

"surprisingly"? D5 1/2 NS contains the same amounts of sodium as 1/2 NS? Why would it be surprising when it's the same exact thing just with added dextrose?

I am trying to understand how D5 in 0.45%NS is considered a hypertonic solution by most sources but you have it listed as hypotonic. In your video, you have the mOsm/kg as 143. My textbook and other sources have it well into the 400s. Is this a mistake?

can u do videos for med student for shelf exam...topics that are tough to understand and stuff like that.

thaaank you :)

Thank youuu!

thank you for this video question..sodium follows water wherever it goes, right??

@mutated__donkey5840

Salih Khamees wrong way. Water diffuses *towards* sodium

Shouldn't we treat D5W as an hypotonic not an isotonic solution since the dextrose is quickly metabolized (as you mentioned)? Because isn't free water extremely hypotonic? Great video, thanks

Nursing student here. It is indeed hypotonic in the body. About 260 mOsm/L if I'm not mistaken (but I'm usually mistaken lol)

EKG would be nice.

Can someone tell me how to determine the flow rate?? i mean when to infuse in 1 hour or 2 hours or in 30 min??

@melanieschneiderman2433

Flow rate is gonna depend on your order. The formula is volume(mL)/time(Hr). So for example: "Infuse 50mL Ancef in 15min": your formula is 50mL/0.25Hr= 200mL/Hr. HOWEVER. Now you have to take the flow rate and use it to determine the drip rate in gtts (drops)/min. THAT formula is [(volume/time in minutes) X DF]. To find the DF (drop factor), we use the flow rate we initially found in our first step (for our equation, that came out to be 200). If the number is 51 or greater, we use a DF of 10. If the number is 50 or less, we use a DF of 60. Because our number is greater than 50, we'll use a DF of 10. Now let's plug everything back into our equation: [(50 mL / 15 min) x 10] = 33.3333 gtts/min. But you can't have a *partial* drop, can you? So we round our answer to 33. To sum it all up: first you find the infusion rate in mL/Hr. Then you use that to find the drop factor. Finally, using the drop factor we calculate our rate in drops per minute.

1st yr resident, interesting KZread channel you've got here. Honestly I'm surprised. I'm @ Dartmouth and my professors all use vodcasting to review classes, a big help for your exams. While I'm paying.... A lot for school, for class, and its all on the web. No need for ignorance. However, this isn't residency level. This is Pre med level

I thought that osmosis is water movement but diffusion is particles movement but

@azharkhan3089

+hadia ali In diffusion the solvent and solute particles move through the membrane. In osmosis the movement is only of the solvent hence a semipermeable membrane is involved.

Isn't half normal saline hypotonic not isotonic..?

@iMedSchool

You are absolutely right. I mispoke! Half normal saline is HYPOTONIC. Thanks for catching that I will correct it. Thanks for watching!

wtf? this would depend on how many ml of medication you have

Remember, these aren't "medications" in the standard sense. Yeah they're meds because you need an order, but the tonicity of the fluid inside the bag isn't going to change whether you've got 50 mL or 1000mL. It's still isotonic NS in there. The only time that tonicity changes is if you have a primary line running NS and someone orders a multi to be added to the bag. That's gonna change things.

You speak too fast =(((
