A pharmacy technician receives a prescription for guaifenesin DM 1 tsp PO q.i.d. x 10 days. The technician prints a label that reads: Guaifenesin Take 10 mL by mouth two × a day for 10 days. What is the total number of errors this label contains?

Rationale

The label contains 2 errors.

The label incorrectly states the dosage frequency and the administration route, leading to a total of two distinct errors. The prescription clearly indicates guaifenesin DM should be taken four times daily (q.i.d.), while the label states only twice daily. Additionally, the label’s volume is also incorrect in terms of the prescribed dosage unit.

A (1) YOUR ANSWER

This choice suggests there is only one error on the label. However, the frequency of administration is incorrect, and the dosage amount is not properly represented. Therefore, identifying just one error is insufficient given the discrepancies present.

B (2) CORRECT

This is the correct choice. The first error is the incorrect frequency of administration, stating "two times a day" instead of the prescribed "four times a day." The second error lies in the failure to specify that the dosage is 10 mL (1 tsp), which could lead to confusion regarding the amount to be taken.

C (3) YOUR ANSWER

This option implies there are three errors in the label. While there are two clear mistakes regarding frequency and dosage description, there is no third error present. Therefore, this choice overestimates the number of errors identified.

D (4) YOUR ANSWER

This choice suggests that there are four errors on the label. However, upon review, only two errors are present: the incorrect frequency and the inaccurate dosage unit. Thus, this option is inaccurate as it exaggerates the number of mistakes.

Conclusion

The label for guaifenesin DM contains two errors: it misstates the frequency of administration and fails to accurately convey the prescribed dosage amount. Recognizing and correcting these errors is crucial for ensuring patient safety and adherence to the prescribed medication regimen. Proper labeling is essential in pharmacy practice to prevent any potential medication errors.
