Question 1

The biophysical profile of a 32-week gestation fetus demonstrates the fetus has a decrease in fetal heart rate reactivity. Which is likely to follow if the loss of oxygenation continues?&#10;A) Loss of fetal tone.&#10;B) Loss of fetal movement.&#10;C) Loss of fetal cardiac activity.&#10;D) Loss of fetal breathing movements

Accepted Answer

Loss of fetal breathing movements is likely to follow a decrease in fetal heart rate reactivity if the loss of oxygenation continues, as it is an early sign of fetal compromise.

Question 2

The biophysical profile is being completed and the fetal heart reactivity in 20 minutes is evaluated to be non-reactive. The mother is not known to have taken any medication that would impact the fetal reactivity. Which of the following is the best response to the findings?

A) Assess for reactivity for an additional 20 minutes.
B) Schedule the woman for a nonstress test another day.
C) Document the nonreactive stress test in the medical record.
D) Continue with the remaining biophysical profile measurements.

A

Accepted Answer

If the fetal heart reactivity is non-reactive in the initial 20 minutes, it is appropriate to extend the assessment for an additional 20 minutes to allow more time for potential reactivity before concluding the test.

Question 3

The practitioner is preparing to measure amniotic volume. Which method, if used, is the most accurate when assessing for oligohydramnios?&#10;A) Choose the first pocket of amniotic fluid found and measure it.&#10;B) Locate multiple amniotic fluid pockets and use the average of the measurements.&#10;C) Find the deepest vertical pocket of amniotic fluid and measure it.&#10;D) Determine the volume of four separate pockets and use the sum of the measures.

Accepted Answer

The deepest vertical pocket of amniotic fluid is the most accurate measurement for oligohydramnios.

Question 4

What is the most significant risk if oligohydramnios continues to be over-diagnosed by practitioners using ultrasound?&#10;A) Maternal bed rest may be prescribed to more women to prevent preterm birth.&#10;B) Intravenous (IV) fluids may be given unnecessarily to the mother as treatment.&#10;C) The fetus may suffer from effects of additional ultrasound testing and maternal stress.&#10;D) More births may be unnecessarily induced based on the concern for the fetal well-being.

Accepted Answer

Over-diagnosis of oligohydramnios can lead to unnecessary interventions, such as inducing labor, due to concerns about fetal well-being, which may not be warranted.

Question 5

Which is the maximum time that should be spent evaluating the biophysical profile parameters using ultrasound?&#10;A) 20 minutes&#10;B) 30 minutes&#10;C) 40 minutes&#10;D) 50 minutes

Accepted Answer

The answer of Which is the maximum time that should...

Question 6

The biophysical profile (BPP) score is 9 based on the Manning's score. Which is the best interpretation of this information?&#10;A) The fetus is in danger and should be delivered.&#10;B) The fetal score suggests asphyxia and the test should be repeated.&#10;C) The fetus may be experiencing asphyxia and needs further testing.&#10;D) The fetal score is within normal limits and no further action is needed.

Accepted Answer

A BPP score of 9 is considered normal, indicating that the fetus is not in distress and no immediate action is needed.

Question 7

The practitioner is preparing to complete a biophysical profile (BPP) examination. Which position is the most appropriate for the woman?&#10;A) Supine with some lateral tilt.&#10;B) Side-lying with both knees flexed.&#10;C) Side-lying with one leg brought forward.&#10;D) Supine with head elevated on two pillows.

Accepted Answer

The supine position with some lateral tilt is most appropriate for a biophysical profile examination as it allows for optimal ultrasound imaging while preventing supine hypotensive syndrome by avoiding full compression of the inferior vena cava.

Question 8

The practitioner needs to view the fetal breathing movements. Which is the best placement of the ultrasound transducer to get the assessment?&#10;A) Over the fetal diaphragm.&#10;B) Over the woman's umbilicus.&#10;C) Over the mother's urinary bladder.&#10;D) Over the fetal cord insertion location.

Accepted Answer

The fetal diaphragm is the best location to observe fetal breathing movements as it directly involves the movement of the diaphragm during breathing.

Question 9

The practitioner doing a fetal movement assessment notes the fetus has flexed and extended each leg separately and rolled its trunk once during the assessment. Which is the best interpretation of this information?

A) The practitioner can give the fetus a full score for fetal movement.
B) The practitioner can only provide a partial score for fetal movement.
C) The practitioner has not seen enough information to provide a score.
D) The practitioner has to wait another 20 minutes to complete the scoring.

Accepted Answer

The fetus has demonstrated a range of movements, including flexion, extension, and trunk rolling, which typically satisfies the criteria for a full score in fetal movement assessments.

Question 10

The practitioner is performing a biophysical profile examination. Which is associated with a fetal breathing score of 2?&#10;A) Two instances of breathing for 20 seconds in a 60-minute time-period.&#10;B) One instance of breathing for 40 seconds in a 30-minute time-period.&#10;C) One instance of breathing for 60 seconds in a 30-minute time-period.&#10;D) Two instances of breathing for 50 seconds in a 60-minute time-period.

Accepted Answer

A fetal breathing score of 2 in a biophysical profile is typically given when there is at least one episode of fetal breathing lasting at least 30 seconds within a 30-minute observation period.
