A nurse is providing education to a client during her first prenatal visit.
Which of the following should the nurse include in the teaching to decrease the risk of preterm labor?

Choice A rationale

Follicle Stimulating Hormone (FSH) is involved in the maturation of ovarian follicles and the menstrual cycle. While it is crucial for fertility, it is not directly responsible for maintaining pregnancy once implantation occurs.

Choice B rationale

Progesterone is essential for maintaining pregnancy. It prepares the endometrium for implantation and supports the early stages of pregnancy by preventing uterine contractions that could dislodge the embryo.

Choice C rationale

Human chorionic gonadotropin (HCG) supports the corpus luteum in early pregnancy, ensuring the continued production of progesterone and estrogen. However, implantation failure is less likely due to a lack of HCG.

Choice D rationale

Prolactin plays a role in lactation and has some influence on reproductive health, but it is not primarily responsible for implantation. A lack of prolactin is less likely to be the cause of failed implantation. .

Choice A rationale

While a history of rheumatic heart disease is significant, it does not directly correlate with the need for priority teaching on Quad screening. This condition requires careful cardiac monitoring and management during pregnancy.

Choice B rationale

A history of preterm labor is important and may require additional monitoring and interventions, but it is not a direct indication for priority teaching on Quad screening, which assesses risk for certain fetal conditions.

Choice C rationale

Exposure to HIV requires careful management and monitoring to reduce the risk of mother-to-child transmission. However, it is not specifically linked to the need for Quad screening, which is focused on detecting chromosomal abnormalities.

Choice D rationale

A history of having a child with spina bifida places this client at higher risk for having another child with neural tube defects or chromosomal abnormalities. Therefore, priority teaching on Quad screening, which includes markers for such conditions, is essential. .
