A nurse is caring for a client with irregular uterine contractions that are mild to palpation.
FHR is 130/min with moderate variability and accelerations noted.
The client has been ambulating in the hallway, took a warm shower, and is now resting in bed.
The client rates pain of contractions at 3 on a 0 to 10 scale.
What potential condition does the nurse suspect?

Umbilical cord compression.

Dysfunctional labor.

Chorioamnionitis.

Iron deficiency anemia.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Umbilical cord compression typically results in variable decelerations in the fetal heart rate, not moderate variability or regular accelerations. It can lead to changes in fetal heart rate patterns, but not regular mild contractions.

Choice B rationale

Dysfunctional labor refers to an abnormal labor pattern, including irregular uterine contractions. The described symptoms fit this condition, as they can cause mild pain and be managed by ambulation, showers, and rest.

Choice C rationale

Chorioamnionitis is an infection of the fetal membranes and amniotic fluid, leading to fever, uterine tenderness, and foul-smelling amniotic fluid, not mild contractions and moderate variability in FHR.

Choice D rationale

Iron deficiency anemia in pregnancy can cause fatigue, pallor, and shortness of breath but does not affect uterine contractions or fetal heart rate.

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.

A. Placenta formation. B. Fertilization. C. Organogenesis. D. Implantation.

Correct Answer is C

Explanation

Choice A rationale

Placenta formation begins shortly after implantation, but it continues to develop throughout the first trimester and into the early second trimester, making it less precise to attribute the first 8 weeks solely to this process.

Choice B rationale

Fertilization occurs within the first week after ovulation, marking the beginning of pregnancy, but it is a singular event that happens prior to the developmental processes vulnerable to teratogens.

Choice C rationale

Organogenesis is the critical period during which the major organs and structures of the fetus form, typically occurring between the third and eighth weeks of gestation. This is the time when the fetus is most susceptible to the effects of teratogens, which can cause congenital anomalies.

Choice D rationale

Implantation occurs approximately 6-10 days after fertilization, embedding the blastocyst into the uterine lining. While crucial, it is not the primary period when teratogenic effects are most significant, as this happens during organogenesis.
