84. A patient was started on a weight-based regimen calling for 10 mg/kg/day, but the weight was entered in pounds instead of kg. What type of error is most likely to occur?
Answer: B
Wrong dose
Entering the patient's weight in pounds instead of kilograms is likely to result in a calculation error that leads to administering a wrong dose. Since the regimen is based on a weight-based calculation, the discrepancy in units directly affects the dosage prescribed.
A) Delayed dose
A delayed dose refers to a situation where the medication is not administered at the scheduled time. In this case, the issue is not about timing but rather the incorrect calculation of the dosage due to unit conversion errors; hence, this option is incorrect.
B) Wrong dose
This option is correct because entering the weight in pounds instead of kilograms will lead to a significant miscalculation of the required medication dosage. For example, if a patient weighs 150 pounds, the correct weight in kilograms is approximately 68 kg, but using pounds directly would result in a much higher calculated dose than intended.
C) Wrong drug
A wrong drug error occurs when a different medication is given instead of the prescribed one. The scenario described does not involve a change in the drug, but rather a miscalculation of the dosage based on incorrect weight units; therefore, this option is incorrect.
D) Omitted dose
An omitted dose means that the patient did not receive their medication at all. In this situation, the patient likely still receives a dose, albeit incorrect due to the weight error, making this option not applicable to the scenario presented.
Conclusion
The error of entering the patient's weight in pounds instead of kilograms directly leads to a wrong dose being calculated and administered. This miscalculation can have serious consequences for patient safety and treatment efficacy. All other options do not accurately reflect the nature of the error caused by unit conversion issues.
