When calculating pediatric drug doses, which safeguard helps prevent dosing errors by ensuring the dose is based on the patient’s actual weight?

• A. Verify weight
• B. Use age-based dosing
• C. Round decimals
• D. Check temperature

Answer: (A)

In pediatrics, many drug doses are calculated using mg per kilogram of body weight, so the most reliable safeguard is to confirm the patient’s actual weight and base the dose on that measurement. This means obtaining an up-to-date weight on a calibrated scale and using that weight to determine the dose, rather than relying on an estimated weight or assuming a typical weight for a child of a certain age. For instance, if the dose is 2 mg/kg and the child weighs 12 kg, the correct dose is 24 mg; guessing a different weight could lead to under- or overdosing. Age-based dosing is less precise because children of the same age can have very different weights. Rounding decimals can also introduce small but clinically meaningful dosing errors, especially with small doses. Checking temperature doesn’t affect weight-based dosing and isn’t a safeguard for dosing accuracy.
