Final answer:
The leading cause of patient harm is True when referring to medication errors, as they can result in significant adverse outcomes for patients. These errors can impact the entire treatment process and its effectiveness. Type II errors in medication can lead to misuse of drugs, underlining the importance of accurate medical information.
Step-by-step explanation:
The question asks whether the leading cause of patient harm is medication errors. The assertion made can be considered True since medication errors are a significant concern in healthcare and can lead to serious patient harm. According to studies and healthcare reports, medication errors can occur at various stages, including prescribing, transcribing, dispensing, administering, and monitoring. These errors can have severe consequences such as increased hospital stays, additional treatment, and in the worst cases, death.
Within the context of this scenario, a Type II error refers to a false negative where a patient may believe a drug is effective at least 75 percent of the time when it actually is not. This could lead to a situation where patients and doctors decide to continue with a medication that may not be effective. Hence, the severity of such a mistake underscores the need for accurate information when choosing treatment options. This also highlights the importance of rigorous clinical trials and error prevention strategies in healthcare.
