Final answer:
The nurse should advise the guardian to offer a chilled teething ring to soothe the infant's discomfort from teething. Teething can cause gums to become swollen and painful and may disrupt sleep but doesn't typically cause a high fever or require delaying solid foods.
Step-by-step explanation:
Guidance on Infant Teething
The correct statement that the nurse should make is: B) "Offer a chilled teething ring for the baby to chew on." This is because teething can be uncomfortable for infants as their gums may become red, swollen, and painful. Providing a chilled teething ring can help soothe their gums and offer relief from the discomfort. It is important to note that teething does not typically cause a high fever, although a low-grade fever might sometimes be present. Additionally, teething might disrupt a baby's sleep patterns due to discomfort, and solid foods do not need to be delayed until teething is complete. Instead, solid foods can be introduced as per a pediatrician's recommendation, usually around this age, regardless of the teething status.
