Distance from the patient, gravity, or infusion pressure do not ensure that small amounts of blood won't contaminate the syringe once it has been connected to the unit.

• A. True
• B. False
• C. Sometimes
• D. Not specified

Answer: (B)

The idea being tested is how much you can rely on physical factors to prevent blood contamination when a syringe is connected to a unit. In practice, just changing the distance from the patient, the effect of gravity, or the infusion pressure does not reliably stop tiny amounts of blood from entering the syringe. Contamination risk persists due to factors like backflow, residual blood in connectors, and the specific design of the connection—areas that aren’t fully controlled by position, gravity, or pressure alone. That’s why the statement is considered not a dependable guarantee. The safer, more reliable approach is to use sterile technique and closed-system connections with proper priming and flushing to minimize any chance of contamination.
