A nurse is reviewing laboratory results of a pregnant patient.Which result will require further assessment?
Rubella titer 1:33.
Serologic test for syphilis (STS) - non-reactive.
Blood type A-negative.
Hemoglobin 12.2 gm/dL.
The Correct Answer is A
A rubella titer of 1:33 indicates a low level of immunity to rubella, which can be dangerous for a pregnant woman and her fetus.
Rubella is a viral infection that can cause birth defects or miscarriage if contracted during pregnancy. A rubella titer of 1:10 or higher is considered protective.
Choice B is wrong because a non-reactive serologic test for syphilis (STS) means that the patient does not have syphilis, which is a bacterial infection that can also harm the fetus if untreated.
Choice C is wrong because blood type A-negative does not require further assessment unless the patient has antibodies to the Rh factor, which can cause hemolytic disease of the newborn if the fetus is Rh-positive.
This can be prevented by giving the patient Rh immunoglobulin injections during pregnancy and after delivery.
Choice D is wrong because hemoglobin 12.2 gm/dL is within the normal range for a pregnant woman, which is 11 to 14 gm/dL.
Hemoglobin is the protein in red blood cells that carries oxygen.
A low hemoglobin level can indicate anemia, which can affect the oxygen delivery to the fetus and increase the risk of preterm labor or low birth weight.

Correct Answer is D
Explanation
Braxton Hicks contractions are irregular, painless uterine contractions that occur throughout pregnancy, but are more noticeable in the third trimester.They do not indicate labor, but rather help in softening and ripening the cervix.
Choice A is wrong because the patient does not need to time the contractions unless they become regular, painful, and closer together, which are signs of true labor.
Choice B is wrong because documenting fetal activity daily is not related to Braxton Hicks contractions.Fetal activity is monitored to assess fetal well-being and detect any signs of fetal distress.
Choice C is wrong because losing the mucus plug is also not related to Braxton Hicks contractions.The mucus plug is a thick plug of mucus that seals the cervical canal during pregnancy and may be expelled before or during labor.
Correct Answer is C
Explanation
A nonstress test (NST) is a test in pregnancy that measures fetal heart rate and reaction to movement.Your pregnancy care provider performs a nonstress test to make sure the fetus is healthy and getting enough oxygen.It’s safe and painless, and gets its name because it puts no stress (nonstress) on you or the fetus.
Choice A is wrong because a nonstress test does not measure the mother’s ability to tolerate the discomfort of labor.A stress test is a different procedure that involves stimulating contractions and monitoring how the fetus responds.
Choice B is wrong because a nonstress test does not measure fetal lie, which is the position of the fetus in the uterus.
Fetal lie is usually determined by ultrasound or physical examination.
Choice D is wrong because a nonstress test does not measure maternal readiness for labor.A nonstress test typically happens after 28 weeks of pregnancy, when fetal heart rate starts reacting to movements.
Maternal readiness for labor is assessed by other factors, such as cervical dilation and effacement.
