Six Rights of IV Fluid Administration:

  • Drug (Fluid)
  • Dose
  • Route
  • Time
  • Documentation

There are two classes of IV fluids that can be administered by veins: Crystalloids & Colloids

Crystalloids- Hypotonic, Isotonic, Hypertonic solutions

Colloids-Blood, Plasma, Human Albumin


  • Isotonic- It has same osmolarity as body fluid (0.9 NS, LR)
  • Hypotonic- It has a lower osmolarity than body fluid (D5w, 0.45 NS)
  • Hypertonic- It has a higher osmolarity than body fluid (3%NS, 5%NS)

Name a reason to give each kind of Crystalloid?

  • Isotonic – Dehydration
  • Hypotonic – Hypernatremia
  • Hypertonic – Ascites, 3rd Spacing


**Remember IV + Oral fluids can cause fluid overload**

NCLEX Question: Which type of IV fluid do you never give to a client with Increased Cranial Pressure?


Answer: Hypotonic solution because it will increase cerebral edema.


NCLEX IV site care:

  1. Inspect site q 2 hours
  2. IV dressing should be clean, dry, secure
  3. IV site should be free from redness, swelling, and tenderness


NCLEX Question: If you notice your client’s IV site was red, swollen, and painful to the touch would you flush to assess patency?


Answer: No discontine IV, notify MD and document


NCLEX Tip: You already know everything you need to pass the NCLEX, we just have to review in order to bring it to the front of your mind!  Good luck studying 🙂

    So for hypertonic solution you use for 3rd spacing or ascites. I was thinking that if a patient was serverly burned you would also give them Hypertonic solution because in burns it causes 3rd spacing correct. Just trying to make sure that i understand this correctly and that i am critically thinking.
