    Hi. I just had an iv done couple days ago and the doctor gave me normal saline. I was wondering how long does it stay in your body and why does it make you thirsty a lot??

    Hi there. I am trying to cite this for an assignment but I’m struggling to find publication date. Can anyone help a girl out?

    • Sorry, I can’t even remember what date I published this! But if you are using APA, I believe you can use the abbreviation “n.d.” (aka no date) when the publication date is not available. Double check that, though. Hope it helps!

    I AM A STUDENT NURSE IN GUYANA AND I ENJOY READING YOU INFORMATION IT IS SIMPLE AND I UNDERSTAND. I LOOK FORWARD FOR OTHER INFORMATION.
    THANK YOU I UNDERSTAND IV FLUIDS ALITTLE MORE AND APPRECIATE IT TOO

    My grandma is in the hospital on these IV solutions . When patients are in the hospitals sometimes the families don’t get the explanations of all the different types of meds. Thank you so much! You have made it so easier to learn.

    I don’t usually post comments but you really deserve it (Learned a lot)… Thank you very much ma’am! Hope that you’ll have more articles and videos.

  7. Im soo glad u help because was confused with other solutions for intravenous therapy nd parts to infuse solution.with this im fully prepared for my end of semester exam tanx

    would you be able to help me understand the fluid resuscitation in DKA , NS followed by 1/2 Ns and then followed by d5 1/2 ?NS

  9. Hi! Can i ask?? Upon reinfusion (end of dialysis treatment), Is it compatible to use Dextrose 5% Water aside from Normal Saline in dialysis treatment?

    I’m not a nurse but a retired science teacher,and I’ve found that a good way to understand osmosis is to remember that it is about which direction water molecules flow .
    Put simply they flow from a place where there is more to a place where there is less of them.
    That is from where the WATER concentration is greater to where the WATER concentration is less.
    Hope this helps
    Cheers from Australia

    Sorry don’t mean to complain, but before you took the egg out of the ” hypertonic”‘ solution, you referenced it as “hypotonic” . This is such a confusing theory!!

    Just a comment on the purpose of D5W (with your comment that it is just to give the patient extra cals, which it is definitely sometimes used for!) We learned about this in patho last week! As you stated, IV D5W is used for rehydration (instead of, for example, sterile water), and the dextrose has nothing to do with fluid imbalance.

    The dextrose is there, however, not just for calories but simply to protect the patient’s RBCs at the tip of the IV needle. The dextrose in the bag is isotonic; this means that the concentration of fluid at the tip of the needle where D5W is dripping in is isotonic, and the RBCs go happily by. If sterile water were infused, you’d have hemolysis, as at the tip of the needle, the water dripping in would greatly dilute the blood (fewer solutes). The circulating RBCs flowing past the needle tip will swell to the point of hemolysis, which is truly dangerous! So D5W is given to protect the body from destruction of RBCs, not just to give patient extra cals. Just thought it was an interesting note that highlighted the importance of understanding tonicity! Thank you so much for your osmosis experiment…it helps me a lot!

    You are Awesome with this! I have not ever seen how simple and simply easy you have explained the IV solutions! Thank you..

    Oh yeah, what’s the difference between intravascular space and intercellular space. Are they components of the ECF?

    • Yes, and the key to remembering that is to recognize the prefixes of each word. “Inter-” means in between, and “Intra-” means inside. So “intravascular” means inside the blood vessels, and “intracellular” would mean inside the cells. But “INTERcellular” would mean between the cells. And fluid that is not inside of the cells would be considered part of the extra-cellular fluid (ECF).

    OMG! that is so cool!!! Thank you for this. I was really struggling with IV solutions in my physiology class. I am now preparing for my finals and now I think I can ace it because of this. 😀 <3
