Which term is defined as 'A reason why something is not advisable or why it should be done'?

• A. Consistency
• B. Contraindication
• C. Contour
• D. Device

Answer: (B)

A contraindication is a reason not to perform a procedure or use a medication because doing so could cause harm. This concept centers on safety, recognizing conditions or factors that make an intervention inappropriate or risky, and often there are absolute or relative forms—some situations mean never proceed, others mean proceed with extra caution or alternative options. For example, an allergy to a drug is a clear contraindication to using that drug, and active bleeding can be a contraindication to certain invasive procedures. The other terms don’t express risk-based avoidance: consistency means steadiness, contour refers to shape, and a device is a tool used to perform tasks.
