When irrigating an open wound with normal saline, it is best to use:

Rationale: A. A bulb syringe delivers low pressure and is less effective for thoroughly cleansing an open wound, especially if debris is present. B. A 20-mL catheter tip syringe allows controlled irrigation with sufficient pressure (approximately 8 psi) to effectively remove debris and contaminants without damaging healthy tissue. This is considered the standard method for wound irrigation. C. Using an IV bag without pressure may not provide adequate force to flush out debris and contaminants. D. Gauze compresses can clean the wound surface but do not provide the irrigation pressure necessary for thorough cleansing.
