Study Notes
Intravenous Therapy Overview
- IV therapy delivers medications and fluids directly into the bloodstream through veins for rapid action.
- Indicated for clients unable to intake adequate fluids orally.
Purposes of IV Therapy
- Supplies fluids when oral intake is insufficient.
- Prevents electrolyte imbalances.
- Provides glucose essential for metabolism.
- Delivers water-soluble vitamins and medications.
- Establishes a lifeline for administering urgently needed medications.
IV Fluid Solutions
- Crystalloids: Small molecules (hypertonic, isotonic, hypotonic) affecting fluid shifts; can cause peripheral and pulmonary edema if over-administered.
- Colloids: Large molecules that remain in intravascular spaces longer, such as albumin and fresh frozen plasma; excessive amounts may lead to congestive heart failure.
Types of Crystalloids
- Hypertonic Solutions: Higher solute concentration, dehydrates cells (e.g., 5% saline); requires monitoring for fluid overload.
- Hypotonic Solutions: Lower solute concentration, hydrates cells (e.g., 0.45% saline); may decrease blood pressure.
- Isotonic Solutions: Same concentration as intracellular fluid; no fluid shifts (e.g., normal saline, lactated Ringer’s) used for fluid maintenance and blood loss.
IV Cannula Sizes and Uses
- Color-coded, varying sizes/gauges for specific clinical purposes:
- 14 G (Orange): Rapid blood transfusion, trauma.
- 16 G (Grey): Rapid fluid replacement.
- 18 G (Green): Blood transfusion, large volume infusions.
- 20 G (Pink): Medications, hydration.
- 22 G (Blue): Suitable for small veins.
- 24 G (Yellow): Fragile veins.
Infusion Administration Sets
- Comprises insertion spike, drip chamber, flow control valve, tubing with secondary port, and protective cap.
Blood Group and Transfusion Compatibility
- Blood types defined by antigens: A, B, AB, or O.
- Rh factor: Rh-positive or Rh-negative.
- Type O is universal donor; Type AB is universal receiver.
Blood Typing and Cross-Matching
- Blood typing determines blood group and Rh factor.
- Cross-matching identifies potential antigen-antibody interactions.
- Screening prevents exposure to blood-borne diseases (e.g., hepatitis, HIV).
Blood Products and Their Uses
- Whole Blood: For acute hemorrhage and blood volume replacement.
- Packed Red Blood Cells: Increases oxygen levels during surgeries/anemia.
- Platelets: For bleeding disorders and platelet deficiencies.
- Fresh Frozen Plasma: Provides clotting factors without the need for cross-matching.
- Albumin: Used as plasma expanders.
Transfusion Reactions
- Hemolysis: Incompatible blood; symptoms include fever, flank pain, reddish urine.
- Febrile Reaction: Sensitivity to blood products; symptoms include fever and flushing.
- Allergic Reaction: Mild sensitivity; symptoms include flushing and urticaria.
- Circulatory Overload: Rapid blood transfusion; symptoms include dyspnea and crackles.
- Sepsis: Contaminated blood; symptoms include high fever and chills.
Urinary Catheterization Overview
- A curved tracheostomy tube is inserted into the stoma to reach the trachea.
Tracheostomy Components
- Outer Cannula: Inserted into the trachea, secured against the neck.
- Obturator: A tool for insertion, retained for emergency reinsertion.
- Cuffed Tubes: Inflatable cuff to prevent aspiration and seal air leakage.
Tracheostomy Care
- Patient positioned in semi-Fowler's position; use hydrogen peroxide and saline for cleaning. Suctioning may be employed as necessary.
Indications for Ostomy Creation
- Conditions include Inflammatory Bowel Disease, cancers, trauma, and birth defects.
- Not all bowel removals result in ostomy; primary end-to-end anastomosis is possible.
Types of Ostomies
- Hartman's Pouch: One stoma with the non-functional bowel sealed.
- Double-Barrel Ostomy: Two stomas, one for effluent, one for mucus secretion.
Ostomy Characteristics and Management
- Ileostomy: Produces liquid drainage with digestive enzymes that can irritate skin; minimal odor due to fewer bacteria.
