Which scenario best illustrates a decision-based error?

A decision-based error occurs when an individual consciously makes a choice that leads to an unintended negative outcome, often due to a decision-making process influenced by various factors such as pressure, time constraints, or judgment. In the scenario of choosing not to follow protocol due to time constraints, the individual is aware of the existing protocols but decides to bypass them in favor of a quicker option. This decision can result in errors, safety risks, or other negative consequences because the individual prioritized speed over following established guidelines.

In this context, the key aspect is the conscious decision-making that leads to a riskier situation. The individual has weighed the options and made a choice, thus exemplifying a decision-based error.

In contrast, the other scenarios depict errors that may stem from lapses in memory or oversight rather than conscious decision-making. Forgetting to include necessary controls implies a lack of attention or recall rather than a decision to omit them. Failing to check equipment is a similar oversight related to diligence rather than a decision made with awareness of the potential consequences. Misinterpreting data results may involve misunderstanding or a lack of knowledge, which is not a decision-based choice but rather a cognitive error.
