Final answer:
The safety concerns that should be addressed privately during the party include the parent not noticing the toddler running out into the street, the placement of the toddler's car seat, and allowing the toddler to climb on the counter near a stove.
Step-by-step explanation:
The safety concerns that should be addressed privately when appropriate during the party are:
- The parent is busy entertaining guests and did not notice the toddler running out in the neighborhood street to get a toy.
- The nurse/mother notes that the toddler's car seat is located in the passenger front seat.
- The parents allow the toddler to climb up on the counter and watch as food is stirred on the stove.
These observations raise safety concerns for the child's well-being and should be addressed privately so that the mother can discuss them with the parents and make the necessary changes to ensure the child's safety.
