A client, at 6 weeks gestation, arrives at the OB clinic for her initial visit and requests to hear the fetal heartbeat.
What should the nurse include in the teaching regarding cardiac development?
The fetal heartbeat can be heard via Doppler by 4 weeks of pregnancy.
The fetal heartbeat can be heard by external Doppler around 10-12 weeks of pregnancy.
You will first feel your baby move in week 24 of pregnancy.
The heart formation begins in week 5 of pregnancy and we can hear it by Doppler at 6 weeks.
The Correct Answer is B
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 C
Explanation
Choice A rationale
Irregular menses are not a direct risk factor for cervical cancer. While they can indicate hormonal imbalances, they are not strongly linked to cervical cancer risk.
Choice B rationale
Menopausal status and hormone replacement therapy (HRT) are more closely linked to breast cancer risks rather than cervical cancer. Cervical cancer is primarily associated with HPV infection.
Choice C rationale
Multiple sexual partners increase the risk of HPV infection, which is the primary cause of cervical cancer. HPV is a sexually transmitted infection that significantly raises the likelihood of developing cervical cancer.
Choice D rationale
A family history of breast cancer is more relevant to breast cancer risk rather than cervical cancer. Cervical cancer risk is more closely linked to HPV infection and sexual behavior.
Correct Answer is ["A","B","C"]
Explanation
Choice A: Give betamethasone 12 mg IM now and repeat in 24 hr.
Rationale: Betamethasone is administered to accelerate fetal lung maturity in cases of preterm labor. Given the client's gestational age of 31 weeks, this intervention is appropriate to help reduce the risk of respiratory distress syndrome in the newborn.
Choice B: Begin loading dose of magnesium sulfate 9 g over 30 min.
Rationale: Magnesium sulfate is used for neuroprotection of the fetus in preterm labor to reduce the risk of cerebral palsy. The loading dose is typically given to achieve therapeutic levels quickly.
Choice C: Position the client in a lateral position.
Rationale: Positioning the client in a lateral position helps improve uteroplacental blood flow and can reduce the intensity of contractions, which is beneficial in managing preterm labor.
