Step-by-step explanation:
The physician is most likely to prescribe ceftriaxone IM plus doxycycline for seven days, PO to a client diagnosed with gonorrhea. According to the Centers for Disease Control and Prevention (CDC), cephalosporins, like ceftriaxone, are often a first choice for treating gonorrhea due to antibiotic resistance. Additionally, co-infection with C. trachomatis is common, and the CDC recommends treating with a combination regimen of ceftriaxone and azithromycin.
