✍️ Sample VA-BC Questions & Answers
1. Which IV solution is considered isotonic and most closely approximates the osmolarity of human blood (approximately 285–295 mOsm/L)?
0.9% Normal Saline has an osmolarity of approximately 308 mOsm/L, making it isotonic and safe for peripheral infusion.
2. In VA-BC practice, reliability in assessment refers to:
Reliability refers to the consistency and reproducibility of assessment results when the test is repeated under similar conditions.
3. What is the most important factor in effective communication with patients regarding maintenance and care?

4. What is an air embolism?
An air embolism occurs when air enters the bloodstream, typically through an open central venous catheter lumen or during insertion/removal. This can lead to serious and potentially life-threatening complications as the air bubble travels to the heart and lungs, obstructing blood flow and oxygen exchange.
5. To prevent bacterial proliferation, a unit of packed red blood cells (PRBCs) must be infused within what maximum time frame from initiation?
Blood products must be infused within 4 hours of initiation per AABB and INS standards to prevent bacterial growth at room temperature.
6. When documenting assessment findings in VA-BC practice, which approach is MOST appropriate?
Assessment documentation must be objective, factual, and comprehensive. Recording measurements, observations, and findings without bias ensures that the documentation is useful for decision-making and withstands scrutiny.
