During her first prenatal visit to the clinic at 7 weeks' gestation, a 24-year-old primiparous client comments, "My blood type is A-negative, and my husband's blood type is B-positive
Will that cause problems with my pregnancy?" The nurse's best response would be: 1. "There is no danger to your baby, but there could be a few minor complications for you. Let's talk about what we can do to prevent those." 2. "We will do a blood test to see if your body is responding to the baby's blood type. If so, we will give the baby some medication to prevent harm." 3. "Because your partner is positive and you are negative, there is some risk to the baby, but because this is your first pregnancy, the risks are very small." 4. "If you were O-negative, you might have ABO incompatibility because of your partner's blood type; but since you are type A, there should be no problem."
