What does the abbreviation DF stand for in IV infusion contexts?

• A. Drop Factor
• B. Dose Factor
• C. Dose Frequency
• D. Duration Factor

Answer: (A)

Drop Factor is the number of drops required to deliver 1 mL of IV fluid through the tubing. This value is used to convert a prescribed mL-per-hour rate into a drip rate in drops per minute. For example, with 1000 mL to infuse over 8 hours using tubing that delivers 20 drops per mL, the drip rate is (1000 × 20) / (8 × 60) ≈ 42 drops per minute. If the tubing is 15 drops per mL, the rate would be about 31 drops per minute. Other terms like Dose Factor, Dose Frequency, or Duration Factor aren’t standard terms for this IV context.
