A client arrives at OB triage with complaints of decreased fetal movement for the past 24 hours.
The client states, "I see the high-risk clinic because I have chronic hypertension and gestational diabetes.”. The nurse applies the external fetal monitors and identifies a fetal heart rate baseline of 120 bpm, absent variability, no accelerations, and recurrent late decelerations.

What fetal heart rate category would the nurse communicate to the provider?

A.

Category 1.

B.

Category 2.

C.

Category 3.

D.

Category 4. .

E.

Category 4. .

Answer and Explanation

The Correct Answer is C

Choice A rationale

Category 1 is a normal fetal heart rate pattern with no signs of fetal distress, which is not applicable in this case.

 

Choice B rationale

Category 2 represents an intermediate category with some concerns, but recurrent late decelerations and absent variability place this scenario in a higher risk category.

 

Choice C rationale

Category 3 indicates abnormal fetal heart rate patterns, including absent variability with recurrent late decelerations, which is associated with potential fetal hypoxia or acidemia and requires prompt intervention.

 

Choice D rationale

There is no Category 4 in fetal heart rate monitoring.

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.

Correct Answer is D

Explanation

Choice A rationale

A family history of breast cancer, particularly in a close relative like a sister, is a significant risk factor for breast cancer.

Choice B rationale

Exposure to radiation, particularly in the chest area, increases the risk of developing breast cancer.

Choice C rationale

Current use of oral contraceptives can slightly increase the risk of breast cancer, though the risk diminishes after stopping the pills.

Choice D rationale

Age less than 25 years is not a risk factor for breast cancer; risk increases with age.
