A nurse is caring for a primigravida who asks about the function of the placenta.The nurse responds correctly when explaining which of the following are functions of the placenta?
Cushions fetus from maternal movement.
Provides thermoregulation.
Metabolic and gas exchange.
Provides a sterile environment.
The Correct Answer is C
Choice A rationale
The placenta does not cushion the fetus from maternal movement. Instead, the amniotic fluid within the amniotic sac provides cushioning and protection to the fetus from external forces and maternal movements.
Choice B rationale
The placenta does not provide thermoregulation. Thermoregulation is primarily managed by the mother’s body. The placenta’s main functions are related to nutrient and gas exchange, hormone production, and waste removal.
Choice C rationale
The placenta is responsible for metabolic and gas exchange. It provides oxygen and nutrients to the fetus while removing waste products from the fetal blood. This exchange occurs through the placental barrier, which separates maternal and fetal blood.
Choice D rationale
The placenta does not provide a sterile environment. The amniotic sac and its fluid help maintain a sterile environment for the fetus. The placenta’s role is more focused on nutrient and gas exchange, hormone production, and waste removal.

Correct Answer is C
Explanation
Choice A rationale
This choice indicates G3-T1-P0-A1-L2. Gravida (G) is the total number of pregnancies, which is correct as 3. Term (T) is the number of pregnancies carried to term (37 weeks or more), which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 0. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 1. Living (L) is the number of living children, which is 2. However, this choice incorrectly counts the preterm delivery as an abortion.
Choice B rationale
This choice indicates G3-T2-P0-A0-L2. Gravida (G) is correct as 3. Term (T) is the number of pregnancies carried to term, which is 2. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 0. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice incorrectly counts the preterm delivery as a term delivery.
Choice C rationale
This choice indicates G3-T1-P1-A0-L2. Gravida (G) is correct as 3. Term (T) is the number of pregnancies carried to term, which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 1. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice correctly accounts for the term and preterm deliveries.
Choice D rationale
This choice indicates G2-T1-P1-A0-L2. Gravida (G) is incorrect as it should be 3. Term (T) is the number of pregnancies carried to term, which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 1. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice incorrectly counts the total number of pregnancies.
Correct Answer is C
Explanation
Choice A rationale
Heartburn and nausea are common symptoms during pregnancy and are not typically considered warning signs that require immediate medical attention.
Choice B rationale
Amenorrhea, or the absence of menstruation, is a normal sign of pregnancy and does not indicate a complication that needs immediate reporting.
Choice C rationale
Abdominal cramping can be a sign of a serious condition such as ectopic pregnancy or miscarriage, and it is important for the client to report this symptom immediately.
Choice D rationale
Urinary frequency is a common symptom during pregnancy due to hormonal changes and the growing uterus pressing on the bladder. It is not typically a warning sign that requires immediate medical attention.
