The nurse reviews a client’s antepartum nonstress test results as reactive. The nurse interprets this finding as:
Two or more fetal heart rate accelerations within a 20-minute period.
No late decelerations of the fetal heart rate.
Late decelerations are present with a minimum of 50% of the contractions.
Fetal heart rate accelerations less than 15 beats per minute or lasting less than 15 seconds.
The Correct Answer is A
Choice A rationale
A reactive nonstress test is defined as having two or more fetal heart rate accelerations of at least 15 beats per minute lasting 15 seconds or more within a 20-minute period.
Choice B rationale
No late decelerations of the fetal heart rate do not define a reactive nonstress test, which focuses on fetal heart rate accelerations as indicators of fetal well-being.
Choice C rationale
The presence of late decelerations in more than 50% of contractions indicates uteroplacental insufficiency and fetal distress, not a reactive nonstress test which requires accelerations.
Choice D rationale
Fetal heart rate accelerations less than 15 beats per minute or lasting less than 15 seconds do not meet the criteria for a reactive nonstress test, which requires accelerations of 15 beats per minute lasting 15 seconds or more.

Correct Answer is A,B,C,D
Explanation
The correct sequence of maternal changes from first to last is:
- Amenorrhea (A) – This is usually the first sign of pregnancy, occurring due to increased progesterone levels and the absence of a menstrual period.
- Goodell’s sign (B) – This refers to the softening of the cervix, which typically occurs around 6-8 weeks of pregnancy due to increased vascularization.
- Quickening (C) – This is the first perception of fetal movement by the mother, usually felt between 16-20 weeks of pregnancy.
- Lightening (D) – This occurs late in pregnancy (around 37-40 weeks) when the fetus descends into the pelvis in preparation for birth.
So, the correct order is:
A → B → C → D.
Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A rationale
Calculating the estimated date of birth involves determining the gestational age. Gestational age is crucial for monitoring fetal development and timing prenatal care.
Choice B rationale
Obtaining the client’s personal and family medical history helps identify genetic risks, potential complications, and health conditions that may affect pregnancy and delivery.
Choice C rationale
Obtaining information about prior pregnancies provides insight into potential risks and outcomes. Previous pregnancy complications can indicate risks for the current pregnancy.
Choice D rationale
Checking the client’s urine with a reagent strip screens for urinary tract infections, protein, and glucose levels. UTIs can cause complications, while protein and glucose levels help monitor maternal health.
Choice E rationale
Scheduling the client for prenatal laboratory testing, such as blood work and ultrasounds, helps assess maternal and fetal health. Tests like blood type, Rh factor, and infectious diseases are essential for prenatal care.
Choice F rationale
Discussing chorionic villus sampling is not necessary at 18 weeks of gestation. CVS is typically performed between 10-13 weeks for early genetic testing.
