A nurse is attending to a first-time pregnant woman who is at term.
She is experiencing contractions but is unsure if she is in labor.
Which of the following should the nurse identify as a labor sign?
The position of the presenting part.
Membrane rupture.
Contraction pattern.
Changes in the cervix.
The Correct Answer is D
Choice D rationale
Changes in the cervix, including effacement (thinning) and dilation (opening), are reliable signs of true labor. During true labor, contractions cause the cervix to thin and open to prepare for the passage of the baby. This is in contrast to Braxton Hicks contractions, or “false labor,” which are irregular and do not result in changes to the cervix.
Choice A rationale
The position of the presenting part can provide information about the progress of labor and the likely need for interventions, but it is not a definitive sign of labor.
Choice B rationale
Membrane rupture, or “water breaking,” can occur before or during labor. However, not all women experience a noticeable rupture of membranes, and sometimes the fluid can leak slowly, making it less noticeable.
Choice C rationale
A regular contraction pattern can be a sign of labor, but contractions can also occur in patterns during false labor. Therefore, contraction pattern alone is not a definitive sign of labor.

Correct Answer is B
Explanation
Choice A rationale
Preparing the abdominal and perineal areas is not the priority nursing action for a client who has a large amount of painless, bright red vaginal bleeding at 38 weeks of gestation. This type of bleeding is suggestive of placenta previa, a condition where the placenta covers part or all of the cervix, preventing normal delivery. While preparing the abdominal and perineal areas may be necessary in preparation for delivery, it is not the immediate priority.
Choice B rationale
Initiating IV access is the priority nursing action for a client who has a large amount of painless, bright red vaginal bleeding at 38 weeks of gestation. This type of bleeding is suggestive of placenta previa, a condition where the placenta covers part or all of the cervix, preventing normal delivery. IV access allows for rapid administration of fluids and medications, which may be necessary to stabilize the client’s condition.
Choice C rationale
Inserting an indwelling urinary catheter is not the priority nursing action for a client who has a large amount of painless, bright red vaginal bleeding at 38 weeks of gestation. While a urinary catheter may be necessary in preparation for delivery or surgery, it is not the immediate priority.
Choice D rationale
Witnessing the signature for informed consent for surgery is not the priority nursing action for a client who has a large amount of painless, bright red vaginal bleeding at 38 weeks of gestation. While obtaining informed consent may be necessary before performing certain procedures or surgeries, it is not the immediate priority.
Correct Answer is A
Explanation
Choice A rationale
The maternal serum alpha-fetoprotein (MSAFP) test is a screening test that measures the level of alpha-fetoprotein in the mother’s blood during pregnancy. It is used to assess the likelihood of certain birth defects, including neural tube defects such as spina bifida.
Choice B rationale
The MSAFP test does not assess fetal lung maturity. Other tests, such as amniocentesis, can be used to assess this.
Choice C rationale
The MSAFP test does not identify Rh incompatibility between the mother and fetus. Rh incompatibility is typically determined through blood typing and antibody screening.
Choice D rationale
While the MSAFP test can provide valuable information about the health of the fetus, it does not assess various markers of fetal well-being. It is specifically used to screen for certain birth defects.
