A nurse is caring for a client who is at 41 weeks of gestation and has a positive contraction stress test. For which of the following diagnostic tests should the nurse prepare the client?
Percutaneous umbilical blood sampling
Amnioinfusion
Biophysical profile (BPP)
Chorionic villus sampling (CVS)
The Correct Answer is C
Choice A Reason:
Percutaneous umbilical blood sampling (PUBS) is not appropriate. This invasive procedure involves sampling blood from the umbilical cord and is not typically used in the context of a positive contraction stress test.
Choice B Reason:
Amnioinfusion is not appropriate. Amnioinfusion is a procedure in which sterile fluid is infused into the amniotic cavity to alleviate conditions such as oligohydramnios. It is not a primary diagnostic test for assessing fetal well-being.
Choice C Reason:
Biophysical profile (BPP) is appropriate. The biophysical profile is a diagnostic test that assesses the well-being of the fetus by evaluating various parameters, including fetal heart rate, fetal breathing movements, fetal movements, fetal tone, and the amniotic fluid volume. This test provides additional information to assess fetal well-being and can help guide decisions about the timing and mode of delivery.
Choice D Reason:
Chorionic villus sampling (CVS) is inappropriate. CVS is a prenatal test used for diagnosing certain genetic conditions but is not indicated in the context of a positive contraction stress test.

Correct Answer is A
Explanation
The correct answer is A. Cervical dilation.
A. Cervical dilation is a definitive sign of labor.
Cervical dilation is the opening of the cervix, and it is a key indicator of the active phase of labor. Measurement of cervical dilation is an essential component of assessing the progress of labor.
B. Brownish vaginal discharge may indicate various things, including the presence of old blood or mucus. While it could be a sign of impending labor, it is not a definitive confirmation of active labor.
C. Amniotic fluid in the vaginal vault could suggest rupture of membranes, but it alone does not confirm the active phase of labor.
D. Pain above the umbilicus is not a specific or conclusive sign of labor. Labor pain typically originates in the lower abdomen and pelvis.
Correct Answer is B
Explanation
The correct answer is B. Just above the symphysis pubis.
A. Just above the umbilicus: At the end of the first trimester, the uterus is still within the pelvic cavity, and fetal heart tones are typically not detectable above the umbilicus at this stage.
B. Just above the symphysis pubis: This is the correct placement for assessing fetal heart tones during the first trimester. The fetal heart is usually located low in the pelvis during early pregnancy, making it most easily heard just above the pubic bone.
C. The right lower quadrant: Fetal heart tones are typically assessed in the midline of the abdomen, and focusing on the lower quadrants may not be the optimal location, especially in the first trimester.
D. The left lower quadrant: Similar to the right lower quadrant, focusing on the lower quadrants may not be the most appropriate location for assessing fetal heart tones during the first trimester.
