Question 1

What is the clinical distinction between infiltration and extravasation during IV infusion?

Accepted Answer

Infiltration involves non-vesicant fluid leaking into surrounding tissue; extravasation involves vesicant agents causing tissue damage

Answer

Infiltration refers to non-vesicant fluid leaking into surrounding tissue causing swelling, while extravasation specifically involves vesicant substances that can cause tissue necrosis.

Question 2

Amphotericin B, an antifungal medication, must be reconstituted and diluted in which specific IV solution to prevent precipitation?

Accepted Answer

D5W (5% Dextrose in Water)

Answer

Amphotericin B is only compatible with D5W; mixing with any saline-containing solution causes the drug to precipitate and become ineffective.
