12. According to ISMP, which dose designation is most likely to lead to an error?
Answer: C
120.0 mcg is most likely to lead to an error.
The dose designation of 120.0 mcg is most likely to lead to an error due to the inclusion of a trailing zero, which can be misinterpreted in certain situations, leading to medication dosing mistakes.
A) 0.2 mg
The designation of 0.2 mg is less likely to lead to an error as it does not include any trailing zeros or other ambiguous formatting. This format is clear and reduces the risk of confusion in dosing.
B) 300 mcg
The designation of 300 mcg is straightforward and does not contain any elements that could lead to misinterpretation. Therefore, it is not as prone to errors in comparison to the option with the trailing zero.
C) 120.0 mcg
The designation of 120.0 mcg is problematic because the presence of a trailing zero can create confusion, as it may be misread as 120 mcg or even lead to a perception of a larger dose. This format is especially susceptible to medication errors.
D) 1.4 mg
The designation of 1.4 mg is clear and does not include any trailing zeros that could lead to misinterpretation. As such, it is not likely to lead to errors in dosage calculations.
Conclusion
The designation of 120.0 mcg is definitively the most likely to lead to an error due to its trailing zero, which can be misread and result in incorrect dosing. In contrast, the other options do not present such risks, making them safer in terms of clarity and accuracy. Thus, the risk associated with trailing zeros is a critical factor in medication safety.
