What does causation mean in a malpractice lawsuit?

• A. A causal connection between the breach and the patient's injury
• B. There was a mistake regardless of harm
• C. The test results being inconclusive
• D. The absence of any harm

Answer: (A)

Causation in a malpractice case means there must be a link between the provider’s breach of the standard of care and the patient’s injury. The claim rests on showing that the breach contributed to or caused the harm, not just that a mistake occurred. If the breach happened but there’s no proven connection to an injury, liability generally can’t attach. In practice, this often involves showing that, but-for the breach, the injury would not have occurred, or that the breach was a substantial factor in producing the harm.

That’s why this option is the best answer: it captures the essential idea that liability depends on a causal connection between the breach and injury. The other statements don’t fit because a simple mistake without proven harm isn’t enough for liability, inconclusive test results don’t address causation, and no harm means there’s nothing to compensate, so causation isn’t established.
