Final answer:
The nurse should encourage breastfeeding as it is protective for the baby, even though the mother smokes, but should also provide counseling about the risks of smoking and support to quit.
Step-by-step explanation:
The nurse's response to a mother who smokes two packs of cigarettes per day and plans to continue after discharge while breastfeeding should be based on the fact that breastfeeding is protective for the baby and should be encouraged. While it's true that smoking can have adverse effects on both the mother and baby, including an increased risk of premature birth, low-birth-weight infants, and sudden infant death syndrome (SIDS), breastfeeding provides significant health benefits to the infant. These benefits may help to mitigate some of the negative effects of the mother's smoking. Moreover, the suggestion to report the mother to child protective services or assume illicit substance abuse solely based on cigarette smoking is not appropriate without further evidence.
