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 B
Explanation
Choice A rationale
Oligohydramnios refers to a condition where there is too little amniotic fluid. An amniotic fluid volume of 1900 mL is above the normal range, indicating that oligohydramnios is not present.
Choice B rationale
Polyhydramnios is the condition of having too much amniotic fluid. The normal range for amniotic fluid volume at 34 weeks gestation is between 800 and 1000 mL. An estimated volume of 1900 mL indicates polyhydramnios, which can be associated with various maternal and fetal conditions.
Choice C rationale
A follow-up glucose test is not directly indicated by the finding of polyhydramnios. While polyhydramnios can be associated with gestational diabetes, the decision to perform a glucose test would depend on other clinical factors and the patient’s history.
Choice D rationale
An amniotic fluid volume of 1900 mL is above the normal range for 34 weeks gestation, so it is not considered normal for gestational age. This finding indicates polyhydramnios rather than a normal fluid level.
Correct Answer is B
Explanation
Choice A rationale
Not providing resources immediately may leave the patient feeling unsupported and isolated. It is important to offer resources and support to help the patient cope with the emotional and psychological impact of terminating a pregnancy due to a genetic abnormality.
Choice B rationale
Discussing the stages of grief is an appropriate nursing action. It helps the patient understand that their feelings are normal and provides a framework for processing their emotions. This support can be crucial in helping the patient navigate their grief and begin the healing process.
Choice C rationale
Encouraging the patient to rethink their decision is not appropriate. The decision to terminate a pregnancy due to a genetic abnormality is often difficult and deeply personal. It is important to respect the patient’s decision and provide support rather than questioning their choice.
Choice D rationale
Encouraging the couple not to share their emotions with each other can be harmful. Open communication between partners is essential for mutual support and understanding during such a challenging time. Encouraging them to share their feelings can strengthen their relationship and help them cope with the loss together.
