31. A community pharmacy receives the following prescription: Digoxin 2.5 mg tablets Take 1 tablet PO daily #30 Pharmacy staff should:
Answer: A
Contact the prescriber for clarification because the medication is not commercially available in the requested strength.
Due to the fact that digoxin is not available in a commercially produced 2.5 mg tablet strength, it is essential to contact the prescriber to confirm the intended dosage or explore alternative options.
A) contact the prescriber for clarification because the medication is not commercially available in the requested strength
This option is correct as it addresses the issue that digoxin is typically available in lower strengths, such as 0.125 mg and 0.25 mg. Since a 2.5 mg strength does not exist, contacting the prescriber is necessary to ensure patient safety and proper medication management.
B) type the prescription as digoxin 2.5 mg tablets with directions that read 'Take one tablet by mouth daily'
This option is incorrect because it suggests processing a prescription for a non-existent strength of digoxin. Typing the prescription as requested would lead to errors in medication dispensing, potentially endangering the patient's health.
C) type the prescription as digoxin 0.25 mg tablets with directions that read 'Take 10 tablets by mouth daily'
This option is also incorrect as it misinterprets the intended dosage by suggesting an excessive quantity of tablets. Taking 10 tablets of 0.25 mg would exceed the originally intended dosage of 2.5 mg, which is inappropriate and unsafe.
D) contact the prescriber for clarification regarding a mismatch between the medication and the route of administration
This option is incorrect as there is no mismatch between the medication and the route of administration indicated in the prescription. The issue lies solely in the strength of the medication requested, not the route.
Conclusion
The necessity to contact the prescriber in option A highlights a critical aspect of pharmacy practice: ensuring that prescriptions are safe and appropriate for patients. Options B, C, and D fail to address the core issue of the non-existent dosage strength, making them unsuitable responses in this scenario. Therefore, option A is the only correct choice that ensures patient safety and adherence to medication guidelines.
