The nurse is providing discharge instructions to a female client who delivered a healthy, full-term infant. What information should the nurse provide about taking medications while breast feeding?

The mother should not take any medication while breast feeding in order to prevent harm to the infant

Many medications cross into the breast milk in small amounts and could cause harm to the infant

While medication can cross into the breast milk, no infants have ever been harmed because of this

It is unlikely that a large enough amount of medication will cross into the breast milk and cause harm to the infant.
