Study procedures required by the protocol may conflict with which of the following?

• A. Standard operating procedures (SOPs)
• B. Budget constraints
• C. Regulatory guidelines
• D. Equipment availability

Answer: (B)

Study procedures in a protocol set the exact steps researchers must follow to ensure reliable results. If those steps require costly tests, extra personnel, or expensive materials, the available budget can’t always cover them. That financial limit creates a clash between what the protocol requires and what the study can actually afford, making budget constraints the most likely source of conflict.

SOPs are standardized methods meant to align with protocols, so they don’t typically create a funding conflict. Regulatory guidelines are mandatory rules to follow, not budget-driven limits. Equipment availability is about having the right tools, which is a logistical constraint, but the question focuses on financial feasibility, where budget constraints directly determine whether the protocol can be implemented as written.
