Two-person checks for certain high-risk doses are intended to prevent what?

• A. They are expensive.
• B. They are rarely used.
• C. They are administered only by physicians.
• D. Because small errors can cause serious harm; require verification by two qualified staff.

Answer: (D)

Two-person checks are a safety measure used for high-risk doses to catch mistakes that could cause significant harm. When medications are potent or have a narrow therapeutic window, even a small error—such as a decimal misplacement, an incorrect concentration, or selecting the wrong drug—can lead to serious injury or death. Requiring a second qualified staff member to verify the drug, dose, route, patient, and timing before administration provides an independent double-check that helps prevent these dangerous errors. This safety step is about protecting patients, not about cost, frequency of use, or who administers the medication.
