Intravenous Therapy Flashcards

Review the types of IV fluids, how to put an IV in, and complications.

1
Q

What is intravenous therapy (IV therapy)?

A

It is giving fluids and other nutrients through a vein.

It is given to clients who can’t take fluids orally or when there is dehydration.

Q

What are the steps to insert an IV?

The nurse is using a translumination device to locate the veins.

A
  1. Select site
  2. Clean the site with disinfectant solution
  3. Apply tourniquet
  4. Insert needle
  5. Check indicator of blood return
  6. Advance catheter
  7. Pull stylette back slightly, advance catheter into vein
  8. Release tourniquet
  9. Apply gentle pressure over the vein at the catheter tip and remove the metal stylette

Q

What is the difference between a peripheral IV site and a central line?

A
  • Peripheral IV site: a short IV that goes into a vein into the arm.
  • Central line: an IV that also goes into a vein but is threaded much further in so that the tip of the catheter site is closer to the heart for quicker administration.

Q

What is a hypotonic solution and what are some examples?

A

Hypotonic solutions are “more watery”. There is a lower concentration of solutes compared to body fluids.

Examples: 0.45% saline, 1/2 normal saline, D2.5W, 0.33%NS

When given, HypOtonic fluids will first go into the vascular space then will shift “Out of the vessels” and into the cells to replace cellular fluid.

Q

Why is a hypotonic solution given for fluid replacement for clients with cardiac or renal disease?

A

Clients with cardiac or renal disease cannot handle extra fluids too quickly.

A hypotonic solution prevents the client from receiving fluids too quickly because it goes into the vascular space and then leaves quickly to go into the cells.

Q

What is an isotonic solution and what are some examples?

A

Isotonic solutions have the same concentration of solutes as body fluids.

Examples: 0.9% NS, Lactated Ringers or LR, D5W, D5 1/4 NS

When given, iSotonic fluids will first go right into the vascular space and then “Stay in the vessels” to treat dehydration.

Q

What is a hypertonic solution and what are some examples?

A

Hypertonic solutions have an increased concentration of solutes as compared to body fluids.

Examples: D10W, 3%NS, 5%NS, D5LR, D5NS, TPN, albumin

When given, fluids will first go into the vascular space and then pull fluids from the 3rd space to go back into the vessels.

What are the **signs and symptoms** of electrolyte overload? | (Immediate Complication)
Occur because **electrolytes control cell and muscle function:** * Calcium and Magnesium imbalances: can cause seizures, coma or dysrhythmias * Potassium imbalances can cause dysrhythmias * Sodium imbalances can cause a coma
57
What are the **interventions** if electrolyte overload from IV fluids is suspected? | (Immediate Complication)

70
What is a **central venous access device** (CVAD)? ## Footnote Also known as a **central venous catheter**, **central venous line** or **central line**.

Peripherally inserted central catheter
77
What **position** should the client be in for central insertion, tubing changes, and line removal for a CVAD?

78
How are blood clots **prevented** with CVADs?
Always flush with **heparin or normal saline** to prevent blood clots from forming on the tip of the catheter.

81
What is used to **clean the insertion site** of a central line?
**Chlorhexadine** and cover with a sterile dressing.
82
What is **worn** by both the nurse and client during a sterile dressing change of a central line?
A mask.
83
What **medication** is given through the central line if a there is a suspected blood clot stuck to the tip of the tubing?
**Alteplase**, a thrombolytic. ## Footnote Alteplase will dissolve the clot so the central line can be used.
84
What are the **steps** for getting a blood culture through a central line?
1. Turn infusions off for at least 1 minute 2. Clean the cap with alcohol 3. Use proximal lumen (the biggest lumen) 4. Get first blood sample and send to lab 5. Clean cap again with alcohol 6.
