A nurse is educating a pregnant client about the Alpha-fetoprotein Test (AFP).

What should the nurse include as a reason why AFP results are reported as multiples of the median (MoM)?

To compare the measured level of AFP to the expected level for a given gestational age.

To differentiate between neural tube defects and chromosomal abnormalities.

To assess the risk of fetal demise or multiple gestation.

To account for factors such as maternal weight and race.

Answer and Explanation

The Correct Answer is A

This is because AFP levels vary according to the gestational age of the fetus, and reporting them as multiples of the median (MoM) allows for a standardized comparison.

Choice B is wrong because AFP results do not differentiate between neural tube defects and chromosomal abnormalities.

They only indicate an increased risk for these conditions, which need further testing to confirm.

Choice C is wrong because AFP results do not assess the risk of fetal demise or multiple gestation.

They only measure the amount of AFP in the maternal blood, which can be affected by various factors such as maternal weight, race, diabetes, and fetal anomalies.

Choice D is wrong because AFP results are reported as MoM regardless of factors such as maternal weight and race.

These factors are taken into account when calculating the MoM value, which adjusts for the expected variation in AFP levels among different populations.

Normal ranges for AFP MoM vary depending on the laboratory and the method used, but generally they are between 0.5 and 2.52.

Values above or below this range may indicate an increased risk for certain fetal conditions or complications.

Correct Answer is B

Explanation

The correct answer is choice B. The nurse should inform her that results are typically available within 7 days.

This is known as the rapid CVS result.

A more detailed set of CVS results will be available within 2 weeks.

Choice A is wrong because 24 hours is too short for the laboratory to test the sample of cells from the placenta.

Choice C is wrong because 10-14 days is the timeframe for the more detailed set of CVS results, not the rapid CVS result.

Choice D is wrong because 30 days is too long for the results to be available.

The woman would need to know the results sooner to make informed decisions about her pregnancy.

A. Cord compression B. Fetal hypoxia C. Normal placental function D. Adequate fetal oxygenation

Correct Answer is A

Explanation

This finding indicates that the umbilical cord is being compressed, which can reduce the blood flow and oxygen supply to the fetus.

Variable decelerations are abrupt decreases in the fetal heart rate (FHR) that vary in shape, duration, and degree of fall below the baseline.

They are seen as W- or U-shaped waves on the monitor.

Choice B is wrong because fetal hypoxia is not indicated by variable decelerations, but by late decelerations, which are gradual decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends.

Late decelerations are associated with uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.

Choice C is wrong because normal placental function is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability (6 to 25 beats per minute) and accelerations (increases in the FHR above the baseline).

Normal placental function ensures adequate fetal oxygenation and well-being.

Choice D is wrong because adequate fetal oxygenation is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability and accelerations.

Adequate fetal oxygenation means that the fetus is not experiencing hypoxia or distress.

Normal ranges for FHR are 110 to 160 beats per minute at term and 120 to 160 beats per minute before term.

Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting less than 90 seconds each.
