ANSWERS BANK WITH VERIFIED
CLINICAL RATIONALES// GRADED A+
1. What is the normal baseline range for the fetal heart rate (FHR)?
A) 100-150 bpm
B) 110-160 bpm
C) 120-170 bpm
D) 130-180 bpm
Answer: B) 110-160 bpm
Rationale: A normal FHR baseline is defined as 110-160 beats per minute (bpm). This
is the established normal range for a term fetus.
2. Which type of FHR variability is generally considered the most indicative of
fetal well-being?
A) Absent
B) Minimal
C) Moderate
D) Marked
Answer: C) Moderate
Rationale: Moderate variability (6-25 bpm amplitude) reflects an intact, well-
oxygenated fetal autonomic nervous system and is a reassuring sign. Absent or
minimal variability can be associated with fetal hypoxia, acidosis, or CNS depression.
3. A Category I FHR tracing must have which type of variability?
A) Absent
B) Minimal
C) Moderate
D) Marked
,Answer: C) Moderate
Rationale: Category I (normal) tracings require moderate variability (6-25 bpm).
Absent or minimal variability, even with other normal features, typically places the
tracing in Category II (indeterminate) or III (abnormal).
4. What is the most reliable indicator of fetal well-being during labor?
A) Maternal blood pressure
B) Fetal heart rate variability
C) Fetal movement counts
D) Amniotic fluid index
Answer: B) Fetal heart rate variability
Rationale: Variability is the single most important predictor of fetal acid-base status
and well-being during labor. It directly reflects the functional integrity of the fetal
central nervous system and oxygenation.
5. An acceleration is defined as an increase in FHR that is:
A) >15 bpm lasting ≥15 seconds in a term fetus
B) >10 bpm lasting ≥10 seconds in any fetus
C) >30 bpm lasting ≥30 seconds in a preterm fetus
D) Any visible increase, regardless of duration
Answer: A) >15 bpm lasting ≥15 seconds in a term fetus
Rationale: In a term fetus, an acceleration is defined as a visually apparent, abrupt
increase in FHR of at least 15 bpm above baseline, lasting at least 15 seconds and
less than 2 minutes.
6. A non-reactive NST after 40 minutes should be followed by:
A) Home fetal movement counts
B) A Biophysical Profile (BPP) or Contraction Stress Test (CST)
C) Repeat NST next week
D) Immediate delivery
Answer: B) A Biophysical Profile (BPP) or Contraction Stress Test (CST)
Rationale: A non-reactive NST (lacking at least 2 accelerations in 20 minutes)
,requires further evaluation. The standard next step is a BPP or CST to assess fetal
oxygenation and well-being more comprehensively.
7. Which condition is most likely to cause absent or minimal FHR variability in a
term fetus?
A) Fetal sleep cycle
B) Maternal fever
C) Fetal acidosis or CNS depression
D) Uterine contractions
Answer: C) Fetal acidosis or CNS depression
Rationale: While a fetal sleep cycle can cause minimal variability, it typically resolves
within 30-40 minutes. Prolonged absent or minimal variability (over 60 minutes) is a
concerning sign that may indicate fetal acidemia, neurologic injury, or the effects of
CNS depressant drugs (e.g., magnesium sulfate, narcotics).
8. What is the primary cause of late decelerations?
A) Fetal head compression
B) Umbilical cord compression
C) Uteroplacental insufficiency
D) Maternal hyperventilation
Answer: C) Uteroplacental insufficiency
Rationale: Late decelerations are caused by uteroplacental insufficiency (decreased
oxygen transfer from the intervillous space to the fetus). This can be due to maternal
hypotension, placental abruption, post-term pregnancy, or preeclampsia. They are a
non-reassuring sign reflecting fetal hypoxemia.
9. What is the cause of variable decelerations?
A) Uteroplacental insufficiency
B) Fetal head compression
C) Umbilical cord compression
D) Fetal movement
, Answer: C) Umbilical cord compression
Rationale: Variable decelerations are caused by umbilical cord compression. They
are abrupt in onset and variable in shape, timing, and duration relative to the
contraction. They are mediated primarily by baroreceptors in response to changes in
fetal blood pressure.
10. A deceleration drops from 140 bpm to 80 bpm over 30 seconds, lasts 45
seconds, and returns to baseline quickly. This is most likely a(n):
A) Early deceleration
B) Late deceleration
C) Variable deceleration
D) Prolonged deceleration
Answer: C) Variable deceleration
Rationale: The description—an abrupt drop in FHR with a rapid return to baseline—
is classic for a variable deceleration caused by cord compression. The "U," "V," or "W"
shape is characteristic.
11. A deceleration lasting 8 minutes requires which intervention first?
A) Immediate cesarean section
B) Continued observation only
C) Evaluation for cause
D) Increase oxytocin
Answer: C) Evaluation for cause
Rationale: Prolonged decelerations (lasting ≥2 minutes but <10 minutes) require
immediate assessment and intervention. The nurse should evaluate for potential
causes such as maternal hypotension, uterine rupture, or cord prolapse while
implementing corrective measures.
12. What is the legal responsibility of the nurse in assessing FHR patterns?
A) To diagnose fetal conditions
B) To correctly identify abnormal FHR patterns and notify the healthcare provider
C) To wait for the provider's interpretation before acting
D) To always perform a vaginal exam first
