53. A nurse is caring for a client who has a suspected ectopic pregnancy at 8 weeks of gestation. An ectopic pregnancy occurs when the fertilized egg implants outside the uterus, most commonly in the fallopian tube. One of the hallmark symptoms of an ectopic pregnancy is unilateral, cramp-like abdominal pain depending on the location of the pregnancy.
A. Uterine enlargement greater than expected for gestational age is not expected in an ectopic pregnancy because the fertilized egg implants outside the uterus, so there is no uterine enlargement.
C. Severe nausea and vomiting are more commonly associated with conditions such as hyperemesis gravidarum or early pregnancy symptoms but are not specific to ectopic pregnancy.
D. A large amount of vaginal bleeding may occur in some cases of ectopic pregnancy, but it is not a consistent or defining characteristic.
