93
Q

What is the role of semi-permeable membranes in fluid dynamics?

A

Semi-permeable membranes allow some substances to pass through while blocking others, facilitating selective fluid and solute movement.

94
Q

What is the difference between crystalloids and colloids?

A

Crystalloids are water with electrolytes and can move between compartments, while colloids contain larger molecules that primarily stay in the intravascular space.

95
Q

Why is understanding fluid movement important for IV therapy?

A

It helps in predicting how fluids will distribute in the body, which is crucial for effective treatment and managing patient outcomes.

96
Q

What are some examples of crystalloids?

A

Normal saline and balanced solutions.

97
Q

What are colloids used for in IV therapy?

A

Colloids are used to expand blood volume and maintain blood pressure by staying in the intravascular space longer.

98
Q

What are vascular access devices used for?

A

To gain access to the bloodstream for administering fluids, medications, or drawing blood.

99
Q

Name three types of vascular access devices.

A

Peripheral venous cannulas, central venous catheters, and peripherally inserted central catheters (PICC lines).

100
Q

What is the purpose of priming an IV line?

A

To remove air bubbles and ensure accurate fluid delivery.

101
Q

What does “intravascular space” refer to?

A

The space within blood vessels where IV fluids are initially administered.

102
Q

What are the signs of fluid overload in the interstitial space?

A

Edema or swelling.

103
Q

How does osmosis differ from diffusion?

A

Osmosis is the movement of water from low to high solute concentration, while diffusion is the movement of solutes from high to low concentration.

104
Q

What is hydrostatic pressure and its role in fluid dynamics?

A

Hydrostatic pressure is the pushing force exerted by fluid volume on blood vessel walls, contributing to fluid movement out of vessels.

105
Q

What does “on” in oncotic pressure mean?

A

Oncotic pressure refers to the pulling force exerted by plasma proteins to keep fluid within the blood vessels.

106
Q

Why is it important to understand the difference between hyper and hypo conditions?

A

It helps in diagnosing and managing conditions like hypertension (high blood pressure) or hypotension (low blood pressure) related to fluid imbalances.

107
Q

What is the significance of drip rates and drop factors for IV therapy?

A

They are crucial for calculating the correct flow rate of IV fluids to ensure proper dosing and patient safety.

108
Q

What should you check if a patient shows signs of fluid imbalance?

A

Monitor for signs of dehydration or fluid overload, and assess vital signs, input/output, and physical symptoms.

109
Q

How is tonicity related to crystalloids?

A

Tonicity describes the concentration of solutes in crystalloids, affecting how fluids move between body compartments.

110
Q

What are some common complications of IV fluid administration?

A

Complications include infection, air embolism, thrombosis, and fluid overload.

111
Q

What considerations are important when setting up an infusion pump?

A

Ensure the correct flow rate is set and verify the fluid type and dosage.

112
Q

What is the role of electrolytes in IV fluids?

A

Electrolytes help maintain fluid balance, nerve function, and muscle function.

113
Q

What should be done if an IV line becomes obstructed?

A

Check for kinks, clots, or other issues and take appropriate actions like flushing or replacing the line.

114
Q

What are the key differences between central and peripheral venous catheters?

A

Central catheters are placed in larger veins for long-term use, while peripheral catheters are used in smaller veins for short-term access.

115
Q

What is the importance of aseptic technique in IV fluid administration?

A

Aseptic technique prevents infections and maintains the sterility of the IV site and equipment.

116
Q

How does the capillary wall function in fluid dynamics?

A
