A client asks her nurse, "My doctor told me that he is concerned with the age of my placenta because I am overdue. What does that mean?" The best response by the nurse is:

Your placenta ages and changes as your pregnancy progresses, and it is given a score that indicates a number of calcium deposits it has. The more calcium deposits, the higher the grade, or number, that is assigned to the placenta. It also means that less blood and oxygen can be delivered to your baby.

Don't worry about it. Everything is fine.

This means that we will need to perform an amniocentesis to detect if you have any placental damage.

Your placenta isn't working properly, and your baby is in danger.
