Correct Answer is A
Explanation
A. "I will make sure that my partner takes all the prescribed medication.": This is the correct answer. Expedited partner therapy involves treating the partner(s) without an initial clinical visit, so ensuring they take all prescribed medications is essential to prevent reinfection.
B. "I will have my partner take the antibiotics if any STI symptoms occur.": This is incorrect because the partner should take the antibiotics regardless of symptoms to effectively treat the infection.
C. "I will have my partner use a condom until I finish the antibiotics.": While condom use is important, it does not replace the need for the partner to receive treatment.
D. "I will tell my partner that it is important to be examined at the clinic.": Although important, expedited partner therapy aims to provide treatment without a clinic visit.

Explanation
Calculation:
Desired dose: 0.25 mg
