A nurse is preparing to perform an amniocentesis on a client who is at 27 weeks of gestation and has pre-term labor.
Which of the following actions should the nurse take before the procedure?
Administer tocolytic medication to stop contractions
Instruct the client to empty her bladder
Obtain informed consent from the client
Monitor fetal heart rate and activity
The Correct Answer is B
Instruct the client to empty her bladder. This is because a full bladder can interfere with the insertion of the needle and increase the risk of injury to the bladder or the uterus. Emptying the bladder also reduces discomfort during the procedure.
Choice A is wrong because administering tocolytic medication to stop contractions is not necessary before amniocentesis. Tocolytic medication can have side effects and should only be used when there is a clear indication of preterm labor.
Choice C is wrong because obtaining informed consent from the client is not a nursing action, but a medical one. The nurse can assist in providing information and answering questions, but the final consent should be obtained by the doctor who will perform the procedure.
Choice D is wrong because monitoring fetal heart rate and activity is not a specific action before amniocentesis, but a routine part of prenatal care. Fetal heart rate and activity can be affected by many factors, such as maternal position, fetal sleep cycle, or maternal blood sugar level.
Monitoring them before amniocentesis does not provide any useful information for the procedure.

Correct Answer is A
Explanation
A white blood cell count of 12,000/mm3 indicates an infection that can trigger pre-term labor.The normal range for white blood cell count in pregnancy is 5.7-15.0×10 9 /L, which is equivalent to 5,700-15,000/mm3.
A count above this range suggests an inflammatory response to an infection.
Choice B is wrong because a hemoglobin level of 11 g/dL is within the normal range for pregnancy, which is 10-14 g/dL.
Choice C is wrong because a platelet count of 250,000/mm3 is within the normal range for pregnancy, which is 150,000-400,000/mm3.
Choice D is wrong because a blood glucose level of 90 mg/dL is within the normal range for pregnancy, which is 70-110 mg/dL.
Correct Answer is B
Explanation
Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm delivery to enhance fetal lung maturity.Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing when the baby breathes.This reduces the risk of respiratory distress syndrome and other complications in preterm infants.
Choice A is wrong because betamethasone does not reduce inflammation in the uterus.
Choice C is wrong because betamethasone does not prevent infection in the amniotic fluid.
Choice D is wrong because betamethasone does not increase blood flow to the placenta.
Normal ranges for gestational age are 37 to 42 weeks.
Preterm birth is defined as delivery before 37 weeks of gestation.Antenatal corticosteroids are recommended for women between 24 and 34 weeks of gestation who are at risk of preterm delivery within 7 days, and may be considered for women at 23 weeks of gestation or between 34 and 37 weeks of gestation depending on the clinical scenario.
