Final answer:
To treat a minor burn, the nursing assistant should use cool, clean water, not grease, butter, or ice water, and avoid applying creams or ointments like Silvadene unless directed by a healthcare provider.
Step-by-step explanation:
To treat a minor burn, the nursing assistant should use cool, clean water. It is important to avoid using substances like grease or butter, as these can trap heat and cause further damage to the tissue. Likewise, using ice water can be too harsh and cause additional damage to the burned area. While silver-based products, such as Silvadene cream, are commonly used in medical settings to prevent infection in burn wounds, initial first aid at home for minor burns should not include any creams or ointments unless instructed by a healthcare provider. Instead, lukewarm water should be used to gently rinse the affected area.
