A nurse is assisting in the care of a client who is scheduled for a cesarean birth based on
the fetal lungs having reached maturity. Which of the following findings indicates that the
fetal lungs are mature?
A. Phosphatidylglycerol (PG) absent 3%
B. Biophysical profile score of 8 18%
C. Lecithin/sphingomyelin (L/S) ratio of 2:1 68% Most selected
D. Nonstress test is reactive 9%
Answer and Explanation
Choice A:
This statement is false. PG is a phospholipid that is present in the amniotic fluid when the
fetal lungs are mature. Its absence indicates immature lungs.
Choice B:
This statement is false. A biophysical profile is a test that assesses the fetal well-being by
measuring five parameters: fetal movement, fetal tone, fetal breathing, amniotic fluid
volume, and fetal heart rate. A score of 8 out of 10 is normal, but it does not indicate lung
maturity.
Choice C:
This statement is true. L/S ratio is a test that measures the amount of two surfactants,
lecithin and sphingomyelin, in the amniotic fluid. Surfactants are substances that reduce
the surface tension of the alveoli and prevent them from collapsing. A ratio of 2:1 or
higher indicates that the fetal lungs are mature and can produce enough surfactant.
Choice D:
This statement is false. A nonstress test is a test that monitors the fetal heart rate in
response to fetal movement. A reactive test means that the fetal heart rate increases by
,at least 15 beats per minute for at least 15 seconds after a fetal movement. This indicates
that the fetus is healthy, but it does not indicate lung maturity.
A nurse is reinforcing teaching with the parents of a newborn about caring for the
umbilical cord stump. Which of the following instructions should the nurse include?
A. Give the newborn a sponge bath until the cord stump falls off. 96% Most selected
B. Wrap the cord in petroleum jelly gauze. 3%
C. Wash the cord daily with mild soap and water. 0%
D. Cover the cord with the diaper. 0%
Answer and Explanation
Choice A:
This statement is true. Giving the newborn a sponge bath until the cord stump falls off
helps to keep the cord dry and prevent infection. The cord stump usually falls off within 10
to 14 days after birth.
Choice B:
This statement is false. Wrapping the cord in petroleum jelly gauze is not recommended,
as it can trap moisture and bacteria and delay the healing process. The cord should be
exposed to air as much as possible.
Choice C:
This statement is false. Washing the cord daily with mild soap and water is not
necessary, as it can irritate the skin and increase the risk of infection. The cord should be
cleaned only when it is soiled with urine or stool, using a clean, damp cloth and then
patting it dry.
Choice D:
, This statement is false. Covering the cord with the diaper can cause friction and pressure
on the cord, which can lead to bleeding or infection. The diaper should be folded below
the cord to avoid contact.
A nurse is assisting with the admission of a client who is in preterm labor at 30 weeks of
gestation and has a new prescription for betamethasone. Which of the following
statements should the nurse make?
A. The purpose of this medication is to increase the fetal heart rate. 0%
B. The purpose of this medication is to stop preterm labor contractions. 3%
C. The purpose of this medication is to halt cervical dilation. 3%
D. The purpose of this medication is to boost fetal lung maturity. 92% Most selected
Answer and Explanation
Choice A:
This statement is false. Betamethasone is a corticosteroid that does not affect the fetal
heart rate. It is given to the mother to accelerate the development of the fetal lungs and
reduce the risk of respiratory distress syndrome and other complications.
Choice B:
This statement is false. Betamethasone is not a tocolytic agent that can stop preterm
labor contractions. It is given to the mother to improve the fetal outcomes in case of
preterm delivery.
Choice C:
This statement is false. Betamethasone does not have any effect on the cervical dilation.
It is given to the mother to enhance the production of surfactant in the fetal lungs and
prevent alveolar collapse.
