Answer to Question 1

C
Antimicrobial agents do not cause phagocytosis of bacterial cells. They do disrupt and weaken the bacterial cell wall; because human cells do not have cell walls, antimicrobial agents are not toxic to human cells. Some agents block the conversion of PABA to folic acid; humans do not synthesize folic acid and are not harmed by this process.

Answer to Question 2

A
Patients receiving testosterone may experience edema secondary to sodium and water retention. Treatment involves discontinuing the drug and giving diuretics if needed. Masculinization of both females and males may occur and boys may experience growth of pubic hair, which is an expected effect. Patients may develop a sensitivity rash at the site of transdermal application. Acne is an expected effect.
