Final answer:

Step-by-step explanation:
The medication most likely to be prescribed for a client with a diagnosis of gonorrhea is ceftriaxone IM plus doxycycline for 7 days PO. According to the Centers for Disease Control and Prevention (CDC), cephalosporins, like ceftriaxone, are often the first choice for treating gonorrhea due to antibiotic resistance. In addition, co-infection with C. trachomatis is common, so a combination regimen of ceftriaxone and doxycycline is recommended to treat both infections.
