Pharmacology & Dosage Calculation
A physician orders an intravenous fluid of D5NS at 100cc/hr.
This is an example of which type of solution?
Explanation
Core Concept: IV fluid osmolarity and compartment fluid shifts.
Clinical Presentation:
- N/A (Pharmacological principle).
Diagnosis:
- N/A.
Management:
- Acute: D5NS (5% Dextrose in Normal Saline) has an osmolarity greater than 375 mOsm/L, making it a hypertonic solution. It draws fluid from the intracellular and interstitial spaces into the intravascular space.
- Long-term: Used for specific maintenance needs or severe hypoglycemia, but requires careful monitoring for fluid overload, hyperglycemia, and hypernatremia.
