Step-by-step explanation:
The best treatment for a patient with superficial blisters from a burn is to treat with silver sulfadiazine. Silver sulfadiazine cream is commonly used in burn wound care to prevent infection. It has antimicrobial properties and can help reduce pain and promote healing. Other options such as using water with mild soap, cleansing gently with hydrogen peroxide, or draining serous fluid and applying topical antibiotic may not be as effective or appropriate in this case. Given the patient's pregnancy, it is important to consult a healthcare professional for proper guidance and to ensure the treatment is safe for both the patient and the baby.
