A nurse is assessing a newborn who was born at 42 weeks of gestation.
Which of the following findings should the nurse expect?

A.

Copious vernix.

B.

Dry, cracked skin.

C.

Increased subcutaneous fat.

D.

Scant scalp hair.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Copious vernix is typically found on preterm newborns, not those born post-term.

 

Choice B rationale

Dry, cracked skin is a common finding in post-term newborns due to prolonged exposure to amniotic fluid.

 

Choice C rationale

Decreased subcutaneous fat is more likely in preterm newborns, while post-term newborns might lose some fat due to nutrient depletion.

 

Choice D rationale

Scant scalp hair is more common in preterm infants, whereas post-term infants usually have more developed hair. .

Correct Answer is A

Explanation

Choice A rationale

Uteroplacental insufficiency leads to late decelerations, which are characterized by a gradual decrease in fetal heart rate after the peak of a contraction. This indicates compromised blood flow between the uterus and placenta, affecting the fetus.

Choice B rationale

Umbilical cord compression usually causes variable decelerations, not late decelerations.

Choice C rationale

Maternal bradycardia does not cause changes in fetal heart rate patterns like late decelerations.

Choice D rationale

Fetal head compression causes early decelerations, which coincide with contractions, not late decelerations.

Correct Answer is B

Explanation

Choice A rationale

The fetal heartbeat cannot typically be heard via Doppler as early as 4 weeks of pregnancy. At this stage, the heart is still developing, and it is too soon for external detection with a Doppler device.

Choice B rationale

The fetal heartbeat is generally detectable by an external Doppler device around 10-12 weeks of pregnancy. This is the period when the heartbeat is strong enough to be picked up by the device.

Choice C rationale

Feeling the baby move, known as "quickening," typically occurs around 18-24 weeks of pregnancy, not 6 weeks. This sensation is different from hearing the heartbeat.

Choice D rationale

While the heart begins to form around week 5, it is not detectable by Doppler at 6 weeks. The technology does not have the sensitivity to detect such an early heartbeat externally.
