The Nurse Is Discussing Vaccines with the Mother of a 4-Year-Old

The nurse is discussing vaccines with the mother of a 4-year-old child who attends a day care center that requires the diphtheria, tetanus, acellular pertussis (DTaP) vaccine.

What information will the nurse include when discussing this with the mother?

A) If she gets the vaccine, both she and her 4-year-old child will be protected.
B) If the 4-year-old child contracts pertussis, it can be passed on to her newborn.
C) The vaccine will not be given to her child while she is pregnant.
D) Vaccinating the 4-year-old will provide passive immunity for her unborn child.
