A nurse is bathing a toddler and notices that she has several bruises. Which of the following actions should the nurse take first?

The correct answer is A: Notify the provider. The nurse should first notify the healthcare provider because it is crucial to address the child's safety and well-being promptly. The provider can assess the bruises, determine if further investigation or intervention is necessary, and ensure the child's safety. Asking the toddler or parents directly may not yield accurate information or could put the child at risk if abuse is involved. Contacting social services should be done only if there is evidence or suspicion of child abuse after consulting with the provider.
