An adolescent was diagnosed with primary syphilis. He has no known drug allergies. The most appropriate treatment would be:
a single dose of cefoxitin (Mefoxin) IM.
a single dose of benzathine penicillin G (Bicillin LA) IM.
cefaxitin (Mefoxin) IM weekly for 3 doses.
benzathine penicillin G (Bicillin LA) IM weekly for 3 doses.
The Correct Answer is B
Rationale:
A. Cefoxitin is not effective against Treponema pallidum, the causative agent of syphilis.
B. A single intramuscular dose of benzathine penicillin G (Bicillin LA) is the recommended treatment for primary syphilis in patients without penicillin allergy. This regimen effectively eradicates the infection and prevents progression.
C. Multiple doses of cefoxitin are unnecessary and not indicated for syphilis.
D. Weekly dosing for 3 weeks of benzathine penicillin G is reserved for late latent syphilis or tertiary syphilis, not primary syphilis.

Correct Answer is B
Explanation
Rationale:
A. Latex condoms can trigger allergic reactions in individuals with latex allergy, so they should be avoided.
B. Synthetic condoms (e.g., polyurethane or polyisoprene) are safe alternatives for individuals with latex allergy and offer STI protection comparable to latex condoms when used correctly.
C. Cervical caps are not effective for preventing STIs and are primarily a contraceptive method for the female partner.
D. Foam spermicide may reduce pregnancy risk but does not reliably protect against STIs and is not a substitute for barrier protection.
Correct Answer is B
Explanation
Rationale:
A. A urethral opening on the dorsal aspect of the glans penis is consistent with epispadias, not hypospadias.
B. Hypospadias is a congenital condition in which the urethral opening is located on the ventral (underside) aspect of the penis, rather than at the tip of the glans. Early detection is important for surgical planning and preventing complications with urination or future sexual function.
C. Inability to retract the foreskin over the glans penis is phimosis and is not diagnostic of hypospadias.
D. Inability to palpate a testicle suggests cryptorchidism, which is unrelated to the urethral meatus position.
