A. "A client should avoid consuming undercooked meat while pregnant." Toxoplasmosis, one of the TORCH infections, can be contracted by eating undercooked or raw meat. Avoiding undercooked meat helps prevent this infection, which can cause severe complications for the fetus.

B. "Obtain an immunization against rubella early in pregnancy." Rubella vaccine (part of MMR) is a live virus vaccine and is contraindicated during pregnancy due to the risk of harm to the fetus. Rubella vaccination should be administered before conception or postpartum.

C. "Seek prophylactic treatment if cytomegalovirus is detected during pregnancy." Currently, there is no prophylactic treatment for cytomegalovirus (CMV) during pregnancy. Prevention focuses on hygiene practices, such as frequent handwashing, especially after handling bodily fluids, to reduce the risk of transmission.

D. "A client should avoid crowded places during pregnancy." While avoiding crowded places may reduce exposure to certain infections, it is not a specific strategy for preventing TORCH infections. Other preventative measures, like avoiding raw meat and practicing good hygiene, are more effective.

B. Pelvic pain: Ectopic pregnancy typically presents with pelvic pain, which may be sharp and localized due to the implantation of the embryo outside the uterus, commonly in the fallopian tube.

C. Uterine enlargement greater than expected for gestational age: In an ectopic pregnancy, the uterus may not enlarge as expected because the embryo is implanted outside the uterus.

D. Copious vaginal bleeding: Vaginal bleeding can occur, but it is usually minimal rather than copious. Severe bleeding may occur if the ectopic pregnancy ruptures.
