Questions and Answers
Study Notes
IV Fluids Overview
- Hypertonic Solution: Contains more particles than water, leading to cell shrinkage.
- Isotonic Solution: Has an equal concentration of solutes and water, maintaining cellular volume.
- Hypotonic Solution: Contains fewer particles than water, causing cells to swell.
Client Monitoring Considerations
- Use an IV pump for clients with:
- Kidney failure to ensure careful fluid management.
- Heart failure to prevent fluid overload.
Potassium Chloride Administration
- Administer Potassium Chloride slowly to minimize the risk of venous inflammation.
IV Bag Label Components
- D5W: Indicates Dextrose 5% in water.
- 0.9% Sodium Chloride: Known as Normal Saline.
- 0.2% Sodium Chloride: Refers to Quarter Normal Saline.
- D5 LR: Indicates Dextrose 5% and Lactated Ringers.
- 0.45% Sodium Chloride: Referred to as Half Normal Saline.
Osmolality of IV Fluids
- Determining osmolality is essential for fluid classification:
- Example of osmolality for specific IV bags: 388 mOsmol/L and 525 mOsmol/L.
Tonicity Classifications for IV Fluids
- Dextrose 5% and Water: Hypotonic.
- Normal Saline: Isotonic.
- Quarter Normal Saline: Hypotonic.
- Dextrose 5% and Lactated Ringers: Hypertonic.
- Half Normal Saline: Hypotonic.
Client IV Fluid Administration
- IV pumps are indicated for:
- Nicole receiving Potassium Chloride.
- Doug with renal failure.
- George with heart failure.
IV Input and Output Tracking
- For a patient on Normal Saline at 150 mL/hour, track total input over 24 hours as 4375 mL; output sections filled as follows:
- 07:00-15:00: 900 mL
- 15:00-23:00: 1200 mL
- 23:00-07:00: 1200 mL
- Total: 3300 mL.
IV Flow Sheet Completion
- Record fluid type, volumes, and timings accurately for each IV bag administered:
- First bag initiated at 10:30 (1000 mL Normal Saline).
- Second bag initiated at 18:30 (1000 mL Normal Saline).
Fluid Replacement for Hemorrhagic Shock
- In cases of significant blood loss (e.g., stab wound):
- Appropriate fluids include Normal Saline and Lactated Ringers due to their isotonic properties.
Fluid Management for Dehydration
- For patients with elevated sodium levels and dehydration, appropriate fluids are:
- Half Normal Saline and D5 and water, to rehydrate effectively without causing further electrolyte imbalance.
