After teaching a pregnant woman about the hormones produced by the placenta, the nurse determines that the teaching was successful when the woman identifies which hormone produced as being the basis for pregnancy tests?
Human placental lactogen (hPL).
Estrogen (estriol).
Progesterone (progestin).
Human chorionic gonadotropin (hCG).
The Correct Answer is D
A. Human placental lactogen (hPL) is a hormone produced by the placenta that helps regulate the metabolism of the mother and fetus, but it is not used as the basis for pregnancy tests. It plays a role in modulating the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus.
B. Estrogen (estriol) is another hormone produced by the placenta, which is important for maintaining pregnancy and preparing the body for childbirth. However, it is not the hormone detected by pregnancy tests. Estriol levels increase significantly during pregnancy but are not used as a marker for pregnancy tests.
C. Progesterone (progestin) is crucial for maintaining the uterine lining and supporting early pregnancy. While it is essential for a successful pregnancy, it is not the hormone that pregnancy tests detect. Progesterone helps prevent uterine contractions and supports the endometrium.
D. Human chorionic gonadotropin (hCG) is the hormone detected by pregnancy tests. It is produced by the placenta shortly after the embryo attaches to the uterine lining. The presence of hCG in the blood or urine is a reliable indicator of pregnancy, which is why it is the basis for pregnancy tests.

Correct Answer is C
Explanation
Choice A reason:
Occasional uterine cramping when the infant nurses is a normal phenomenon that occurs as the uterus contracts and returns to its pre-pregnancy size. This is not a sign of infection or complication and does not need to be reported.
Choice B reason:
Descent of the fundus one fingerbreadth each day is also a normal finding that indicates the uterus is involuting properly. The fundus is the top of the uterus that can be felt through the abdomen. It should be at the level of the umbilicus immediately after delivery and then descend about one fingerbreadth (or 1 cm) each day until it reaches the pelvic brim by 10 days postpartum.
Choice C reason:
Reappearance of red lochia after it changes to serous is an abnormal sign that may indicate uterine atony, subinvolution, or retained placental fragments. Lochia is the vaginal discharge that occurs after childbirth, consisting of blood, mucus, and tissue. It usually changes from red to pink to brown to yellow-white over a period of several weeks. If it becomes red again, it may mean that there is bleeding from the uterus or infection in the endometrium. This should be reported to a health care provider as soon as possible.
Choice D reason:
Oral temperature that is 37.2 C (99 F) in the morning is within the normal range and does not indicate fever or infection. A slight elevation in temperature may occur due to dehydration, breast engorgement, or hormonal changes. This does not need to be reported unless it exceeds 38 C (100.4 F) or persists for more than 24 hours.
Correct Answer is C
Explanation
Choice A reason:
This is incorrect because WIC does not provide immunizations for high-risk infants and children. Immunizations are provided by other health care services, which WIC may refer participants to.
Choice B reason:
This is incorrect because WIC does not screen for infants with developmental disorders. WIC provides nutrition education and referrals to other health and social services but does not diagnose or treat any medical conditions.
Choice C reason:
This is correct because WIC provides supplemental food supplies to low-income pregnant or breastfeeding women, as well as infants and children up to age 5 who are at nutritional risk. The food packages are designed to meet the special nutritional needs of the participants and include items such as fruits, vegetables, milk, cheese, cereal, bread, juice, peanut butter, eggs, and infant formula.
Choice D reason:
This is incorrect because WIC does not provide well-child examinations for infants and children living at the poverty level. WIC may refer participants to other health care services that provide such examinations but do not conduct them themselves.
