A pediatric client is hospitalized with a severe case of impetigo contagiosa. Which antibiotic does the nurse anticipate the healthcare provider will order for this client?
1. Dicloxacillin (Pathocil)
2. Rifampin (Rifadin)
3. Sulfamethoxazole and trimethoprim (Bactrim)
4. Metronidazole (Flagyl)
Correct Answer: 1
Rationale: A systemic antibiotic will be given for severe impetigo because it is a bacterial infection. Dicloxacillin is used in treatment of skin and soft-tissue infections. It is specific for treating staphylococcal infections. Rifampin is an antitubercular agent, sulfamethoxazole and trimethoprim are used as a prophylaxis against Pneumocystis carinii pneumonia (PCP), and metronidazole is used to treat anaerobic and protozoic infections.
