Question 37

The quantity does not match the directions.

The prescriber should be contacted because the quantity of inhalation solution prescribed does not align with the instructions given. The prescription indicates using 1 vial four times a day for 10 days, which totals 40 vials, yet only 30 vials are provided in the carton.

A) the package size is incorrect.

This option is incorrect because the package size of 30 vials is acceptable; however, it does not fulfill the total quantity required for the prescribed duration. The issue lies not in the package size itself but in the quantity needed based on the dosing instructions.

B) the dosage is outside the appropriate range.

This option is incorrect as the dosage of 0.5 mg/3 mg for Ipratropium bromide/albuterol sulfate is within the standard therapeutic range for this medication. There is no indication that the dosage prescribed is inappropriate or unsafe based on the information provided.

C) this medication is only available as a metered-dose inhaler.

This option is incorrect because Ipratropium bromide/albuterol sulfate is available in various forms, including nebulizer solutions. Therefore, the availability of the medication does not warrant contacting the prescriber, as the formulation given in the prescription is indeed a valid form.

D) the quantity does not match the directions.

This option is correct. The prescription states to use 1 vial four times a day for 10 days, which totals 40 vials. The pharmacy only has a carton of 30 vials, indicating a discrepancy that necessitates contacting the prescriber for clarification or a potential correction.

Conclusion

Option D is the correct rationale for contacting the prescriber, as the total quantity of vials prescribed exceeds what is available in the carton. The other options either misinterpret the dosage, package size, or availability of the medication, failing to address the actual issue at hand, which is the mismatch between the prescription's quantity and the supplied amount.
