A nurse is assessing a client who has placenta previa and is receiving fetal monitoring.
Which of the following clinical findings should the nurse expect?
Variable decelerations.
Painless vaginal bleeding.
Rigid abdomen.
Uterine tachysystole.
The Correct Answer is B
Choice A rationale
Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause
variable decelerations on fetal monitoring.
Choice B rationale
Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates
or effaces.
Choice C rationale
A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in
placenta previa.
Choice D rationale
Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use
or other uterine stimulants.

Correct Answer is B
Explanation
Choice A rationale
Elevated BUN levels (25 mg/dL) can indicate kidney dysfunction, dehydration, or high protein intake. However, it’s not directly related to a prenatal complication, though it still
requires monitoring.
Choice B rationale
Hemoglobin (Hgb) of 10.2 mg/dL is below the normal range (11 to 16 mg/dL) and can indicate anemia. During pregnancy, anemia can lead to serious complications such as preterm
birth and low birth weight, making this result significant.
Choice C rationale
A fasting blood glucose level of 70 mg/dL falls within the normal range (70 to 110 mg/dL) and does not indicate a complication. Thus, it is not concerning in the context of prenatal
complications.
Choice D rationale
Hematocrit (Hct) of 32% is slightly below the normal range (33 to 47%), which can be common in pregnancy due to increased plasma volume. While monitoring is required, it’s not as
critical as anemia.
Correct Answer is A
Explanation
Choice A rationale
Methadone is often prescribed to pregnant women with opioid use disorder and is considered safe for breastfeeding. Breastfeeding can provide additional benefits such as bonding
and transferring antibodies to the infant.
Choice B rationale
Methamphetamine use during pregnancy is linked to fetal growth restriction, preterm birth, and low birth weight, not fetal macrosomia (large body size).
Choice C rationale
Reducing environmental stimuli is essential for neonates exposed to substances in utero. Increased stimuli can overwhelm their underdeveloped nervous systems, leading to stress
and adverse outcomes.
Choice D rationale
Fetal alcohol syndrome is characterized by growth deficiencies, facial abnormalities, and central nervous system dysfunction. An increased head circumference is not a typical
feature; rather, microcephaly (small head circumference) is more common.
