Final answer:
A pregnant woman should avoid bologna due to the risk of Listeria infection, which can be harmful to the fetus. Instead, she should focus on nutritious foods that are rich in essential vitamins and minerals, so the correct option is 1.
Step-by-step explanation:
Among the foods listed for a pregnant woman, the nurse should advise the client to avoid consuming bologna. This is because bologna is a refrigerated cold cut that can contain Listeria, a pathogen which pregnant women are more vulnerable to due to elevated progesterone levels.
Listeria infection is particularly dangerous during pregnancy as it can cross the placenta, leading to miscarriage, stillbirth, or severe neonatal infections.
It is crucial for pregnant women to consume a diet rich in nutritious foods like fruits, vegetables, whole grains, beans, and legumes, for the adequate intake of vitamins and minerals.
Important nutrients include folic acid, calcium, iron, and omega-3 fatty acids. Foods like cantaloupe, asparagus, and popcorn do not pose the same level of risk for Listeria infection and can be part of a healthful diet during pregnancy.
So, the correct option is 1.
