Rh incompatibility can occur if the client is Rh-negative and the:
a. fetus is Rh-negative.
b. fetus is Rh-positive.
c. father is Rh-positive.
d. father and fetus are both Rh-negative.
ANS: B
For Rh incompatibility to occur, the mother must be Rh-negative and her fetus Rh-positive. If the fetus is Rh-negative, the blood types are compatible and no problems should occur. The father's Rh factor is a concern only as it relates to the possible Rh factor of the fetus. If the fetus is Rh-negative, the blood type with the mother is compatible. The father's blood type does not enter into the problem.
