A client who is 4-days postpartum calls the clinic and reports to the nurse that her nipples are so sore that she does not know if she can continue to breastfeed her infant. Which instruction is best for the nurse to provide?

Apply hot packs just before each feeding.

Allow the nipples to rest by supplementing with formula every other feeding.

Wash the nipples with soap to prevent infection from occurring.

Let the nipples air dry thoroughly after each feeding.
