Final answer:
The nurse should advise b. offering a clean, cool teething ring for the baby to chew on. Avoid giving aspirin for relief during teething.
Step-by-step explanation:
The nurse should make the statement B, which is to offer a clean, cool teething ring for the baby to chew on. Teething can cause discomfort for babies, as the gums may become red, swollen, and painful. Providing a teething ring can help alleviate the discomfort by providing a safe and appropriate object for the baby to chew on.
It is important to note that statement D, which suggests giving the baby aspirin for relief during teething, is incorrect. Aspirin should not be given to infants or young children due to the risk of Reye's syndrome, a rare but serious condition.
