A nurse is caring for a primigravida who asks about the function of the placenta.Which of the following are functions of the placenta?
Provides thermoregulation.
Cushions fetus from maternal movement.
Metabolic and gas exchange.
Provides a sterile environment.
The Correct Answer is C
Choice A rationale
The placenta does not provide thermoregulation; that function is managed by maternal thermoregulation and the amniotic fluid which insulates the fetus.
Choice B rationale
Amniotic fluid cushions the fetus from maternal movements, not the placenta. The placenta's role is more focused on nutrient and waste exchange.
Choice C rationale
The placenta facilitates metabolic functions and gas exchange, supplying oxygen and nutrients to the fetus while removing carbon dioxide and waste products, ensuring fetal development.
Choice D rationale
The placenta doesn't provide a sterile environment. This is accomplished by the amniotic sac and amniotic fluid. The placenta connects the fetus to maternal blood supply, ensuring necessary exchanges for fetal growth.

Correct Answer is B
Explanation
Choice A rationale
Umbilical cord compression typically results in variable decelerations in the fetal heart rate, not moderate variability or regular accelerations. It can lead to changes in fetal heart rate patterns, but not regular mild contractions.
Choice B rationale
Dysfunctional labor refers to an abnormal labor pattern, including irregular uterine contractions. The described symptoms fit this condition, as they can cause mild pain and be managed by ambulation, showers, and rest.
Choice C rationale
Chorioamnionitis is an infection of the fetal membranes and amniotic fluid, leading to fever, uterine tenderness, and foul-smelling amniotic fluid, not mild contractions and moderate variability in FHR.
Choice D rationale
Iron deficiency anemia in pregnancy can cause fatigue, pallor, and shortness of breath but does not affect uterine contractions or fetal heart rate.
Correct Answer is C
Explanation
Choice A rationale
G4T1 P1 A1 L2 implies the client has been pregnant 4 times, with 1 term birth, 1 preterm birth, 1 abortion, and 2 living children. This does not include the correct number of pregnancies or abortions for this client.
Choice B rationale
G5T2 P0 A2 L2 indicates 5 pregnancies, 2 term births, no preterm births, 2 abortions, and 2 living children. This does not correctly account for the preterm birth and abortion history provided.
Choice C rationale
G5T1 P1 A2 L2 is the correct answer, as it denotes 5 pregnancies (including the current one), 1 term birth, 1 preterm birth, 2 abortions, and 2 living children, aligning with the client's history.
Choice D rationale
G5T1 P1 A1 L3 indicates 5 pregnancies, 1 term birth, 1 preterm birth, 1 abortion, and 3 living children. The client has only 2 living children, so this is incorrect.
