IV Fluids Made Easy Flashcards
Name the isotonic IV solutions mentioned?
0.9% sodium chloride, D5W, lactate ringers
What does isotonic mean by definition?
The same as blood in the vascular space
What is a key way to remember isotonic solutions?
ISO stays where I put it
What is an isotonic solution?
A solution that stays in the vascular space without moving into cells, having no effect on body cells.
When is an isotonic solution used?
To replace fluid in the vascular space, especially after trauma or blood loss.
Who should avoid isotonic solutions?
Cardiac patients, renal patients, and those with hypertension.
What happens when isotonic solution is administered?
It increases the volume and pressure in the vascular space.
What is the only isotonic solution compatible with blood?
0.9 percent sodium chloride.
What characterizes hypotonic solutions?
Hypotonic solutions move out of the vessel and into the cell, causing cell swelling.
When are hypotonic solutions used?
For rehydration of cells and treating dehydration.
Why are hypotonic solutions safe for renal or cardiac patients?
They do not stay in the vascular space, thus not increasing volume or pressure.
What condition can hypotonic solutions treat?
Hypernatremia, due to high sodium concentration.
What is used to treat hypernatremia?
Hypotonic solutions are used to treat hypernatremia by providing low sodium concentration.
What should be monitored when using hypotonic solutions?
Monitor the patient for edema as cells swell when fluid moves into them.
What characterizes hypertonic solutions?
Hypertonic solutions have a greater concentration than isotonic solutions, like 3% sodium chloride vs 0.9%.
What happens to cells when hypertonic solutions are administered?
Cells shrink as fluid is drawn out into the vascular space.
Who should avoid hypertonic solutions?
Hypertensive, cardiac, and renal patients should avoid hypertonic solutions due to increased vascular pressure.
When are hypertonic solutions indicated?
Hypertonic solutions are used to treat peripheral edema and third spacing by drawing fluid back into the vascular space.
What is a risk of using hypertonic solutions?
They can cause fluid volume excess and hypertension.
What is a key benefit of studying related content side by side?
Studying related content together enhances memory retention and understanding of differences.
Which IV fluid is safe for hypertensive patients?
Hypotonic solution is safe for hypertensive patients.
Which IV fluid treats hypernatremia?
Hypotonic solution treats hypernatremia.
Which IV fluid is used for edema assessment?
Hypotonic solution is used for edema assessment.
Which IV fluid is compatible with blood?
Isotonic solution is compatible with blood.
Which IV fluid is used for burns and edema?
Hypertonic solution is used for burns and edema.
