1) Administration of antibiotics
2) Application of hot packs to the area
3) Incision and drainage
4) Antibiotics administration followed by I & D
Oral Surgery
Answer: 3
The treatment of choice for a patient with a localized infection and pus formation, especially if they are afebrile (without fever), is incision and drainage (I & D). This involves creating a small opening in the skin to allow the pus to drain out. While antibiotics can be used as an adjunctive therapy to prevent the spread of infection, they are not always necessary in the initial management of a localized abscess if it is managed effectively with I & D.

2. On the day of dialysis
3. One day after dialysis
4. One week after dialysis
Oral Surgery
