Question 51

Two tablets by mouth on the first day then one tablet daily for the next 4 days

Patients instructed to use Z-Pak 250 mg tablets should take two tablets on the first day followed by one tablet daily for the next four days. This dosing regimen aligns with the standard prescription of azithromycin in a Z-Pak.

A) Two tablets by mouth daily on the first two days then one tablet daily until gone

This option is incorrect because it suggests taking two tablets daily for the first two days, which is not the recommended dosing schedule. The correct protocol specifies two tablets on the first day only, followed by a single tablet daily thereafter.

B) Two tablets by mouth on the first day then one tablet daily for the next 4 days

This option is correct as it accurately reflects the typical dosing regimen for Z-Pak. Patients start with two tablets on the first day and then continue with one tablet daily for the next four days, totaling a 5-day course of treatment.

C) Two tablets by mouth on the first day then one tablet daily for the next 5 days

This option is incorrect because it inaccurately extends the duration of the single tablet dosage to five days after the initial double dose. The correct regimen specifies only four days of the single tablet following the first day.

D) One tablet by mouth on the first day then two tablets daily until gone

This option is incorrect because it reverses the initial dosage and suggests taking more than the recommended amount. The proper dosage starts with two tablets on the first day, not one.

Conclusion

The correct answer, B, accurately represents the prescribed dosage for Z-Pak, which is crucial for ensuring effective treatment of infections. All other options misinterpret the dosage schedule, leading to incorrect administration that could compromise treatment efficacy. Understanding the correct regimen is essential for patient compliance and successful outcomes.
