During preconception counseling, the nurse explains that during the first 8 weeks the fetus is most vulnerable to the effects of teratogens.
What is occurring during the first 8 weeks of gestation?
Placenta formation.
Fertilization.
Organogenesis.
Implantation.
The Correct Answer is C
Choice A rationale
Placenta formation begins shortly after implantation, but it continues to develop throughout the first trimester and into the early second trimester, making it less precise to attribute the
first 8 weeks solely to this process.
Choice B rationale
Fertilization occurs within the first week after ovulation, marking the beginning of pregnancy, but it is a singular event that happens prior to the developmental processes vulnerable to teratogens.
Choice C rationale
Organogenesis is the critical period during which the major organs and structures of the fetus form, typically occurring between the third and eighth weeks of gestation. This is the
time when the fetus is most susceptible to the effects of teratogens, which can cause congenital anomalies.
Choice D rationale
Implantation occurs approximately 6-10 days after fertilization, embedding the blastocyst into the uterine lining. While crucial, it is not the primary period when teratogenic effects are
most significant, as this happens during organogenesis.

Correct Answer is C
Explanation
Choice A rationale
Decreased deep tendon reflexes are not typically associated with preeclampsia. In fact, hyperreflexia or increased deep tendon reflexes might be observed due to central nervous
system irritability in preeclampsia.
Choice B rationale
Uterine contractions are related to labor and not a specific indicator of preeclampsia. While they might occur simultaneously, they are not diagnostic of preeclampsia.
Choice C rationale
Proteinuria, the presence of excess protein in the urine, is a key diagnostic criterion for preeclampsia. It indicates kidney involvement and is used along with elevated blood pressure to diagnose this condition.
Choice D rationale
Increased blood glucose levels are associated with gestational diabetes rather than preeclampsia. Elevated blood pressure and proteinuria are the hallmarks of preeclampsia.
Correct Answer is B
Explanation
Choice A rationale
Monitoring the newborn's blood pressure does not directly address symptoms like diaphoresis, jitteriness, and lethargy. These symptoms indicate an immediate need to check blood glucose levels for hypoglycemia.
Choice B rationale
Obtaining blood glucose by heel stick is the correct step because diaphoresis, jitteriness, and lethargy in a newborn are classic signs of hypoglycemia. Timely detection and correction of blood glucose levels are critical.
Choice C rationale
Placing the newborn in a radiant warmer might help maintain body temperature but does not address the root cause of the symptoms, which is likely hypoglycemia.
Choice D rationale
Initiating phototherapy is used to treat jaundice (high bilirubin levels) and is not indicated for managing symptoms of hypoglycemia like diaphoresis, jitteriness, and lethargy.
