A nurse is reinforcing teaching about reliable sources of Vitamin B12 with a client who is pregnant. Which of the following foods should the nurse recommend in the teaching?

Choice A rationale: RhoGAM is not given solely based on blood loss. It is administered to prevent Rh isoimmunization, which is unrelated to the amount of blood loss.
Choice B rationale: If the client has previously given birth to an Rh-negative infant, she is already sensitized and would not require RhoGAM for this current ectopic pregnancy.
Choice C rationale: Rho(D) Immune globulin (RhoGAM) is given to Rh-negative individuals to prevent the development of Rh isoimmunization, which could occur if the client is exposed to Rh-positive blood. In the case of an ectopic pregnancy, there may be a possibility of fetal blood mixing with the mother's bloodstream, which could lead to sensitization in an Rh-negative individual.
Choice D rationale: The desire to conceive again does not dictate the need for RhoGAM. It is solely based on the client's Rh factor status and the potential for sensitization during the ectopic pregnancy.

Choice A rationale: Cephalopelvic disproportion is a condition where the baby's head is too large or the mother's pelvis is too small for a vaginal delivery. Amniocentesis does not provide information about this condition.
Choice B rationale: Amniocentesis can be used to detect neural tube defects such as spina bifida and anencephaly.
Choice C rationale: Rh incompatibility occurs when the mother is Rh-negative, and the fetus is Rh-positive. This can lead to hemolytic disease of the newborn (HDN) if untreated. While Rh incompatibility can be detected through blood tests (maternal blood), amniocentesis is typically not used to diagnose this condition.
Choice D rationale: Amniocentesis can be used to determine the fetal gender by analyzing the DNA in the amniotic fluid. This is not the primary purpose of amniocentesis, but it can certainly identify the gender, especially in cases where this information is needed for medical reasons, such as gender-linked genetic disorders.
Choice E rationale: Amniocentesis is commonly used to screen for chromosomal abnormalities such as Down syndrome (trisomy 21) and other genetic conditions.
