IV Flashcards
(15 cards)
What are the Five R’s of Fluid Administration?
Right patient, Right fluid, Right dose, Right route, Right time
These are essential principles for safe fluid administration.
What is the difference between Crystalloid and Colloid fluids?
Crystalloids are solutions of salts and sugars in water, while colloids contain larger molecules that do not easily cross capillary membranes.
Crystalloids include Normal Saline; colloids include Albumin.
What is Normal Saline used for in intravenous therapy?
Volume expander, maintains hydration, and is non-allergenic
It is commonly used for fluid replacement.
What is a risk associated with using Colloid fluids?
Allergic reaction risk and cardiac risk
Colloids, such as Albumin, can pose these risks.
What is the main purpose of Albumin in IV therapy?
Plasma expander and maintains Hgb & Hct
It is essential for maintaining oncotic pressure.
What is Total Parenteral Nutrition (TPN)?
Fluid delivery method providing all nutritional requirements intravenously
TPN is used when a patient cannot eat or absorb nutrients through the gastrointestinal tract.
What does Poiseuille’s law state?
Length and diameter of a tube affects flow; doubling the diameter increases flow 16x
This law is crucial for understanding fluid dynamics in IV therapy.
What are common mechanisms for fluid delivery in IV therapy?
- Indwelling Venous Catheter
- Port-A-Cath
- Huber Needle
- Peripherally Inserted Central Catheter (PICC)
- Central Venous Catheter (CVC)
These devices are used to administer fluids and medications.
What does Central Venous Pressure (CVP) indicate?
It reflects the pressure in the thoracic vena cava, indicating right heart function and fluid status
Increased CVP may suggest fluid overload; decreased CVP may indicate hypovolemia.
What is the function of a Pulmonary Artery Catheter?
Monitors hemodynamics, including pulmonary artery pressure
It is used in critically ill patients to assess cardiac function.
What is a Phlebostatic Axis?
An anatomical reference point for leveling pressure transducers
It is crucial for accurate hemodynamic monitoring.
What is the pressure in a pressure bag typically set to?
300 mmHg
This is used to maintain flow in IV lines.
True or False: Arterial Catheter Transducer measures central venous pressure.
False
It measures arterial pressures, not central venous pressures.
Fill in the blank: The risk of _______ is associated with the use of colloids.
Allergic reaction
Colloids contain larger molecules that can provoke immune responses.
What is the purpose of an Arterial Waveform in monitoring?
To assess the hemodynamic status and arterial pressure dynamics
Analyzing the waveform helps in diagnosing cardiac conditions.
