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
The placenta does not provide thermoregulation; that function is managed by maternal thermoregulation and the amniotic fluid which insulates the fetus.
Choice B rationale
Amniotic fluid cushions the fetus from maternal movements, not the placenta. The placenta's role is more focused on nutrient and waste exchange.
Choice C rationale
The placenta facilitates metabolic functions and gas exchange, supplying oxygen and nutrients to the fetus while removing carbon dioxide and waste products, ensuring fetal development.
Choice D rationale
The placenta doesn't provide a sterile environment. This is accomplished by the amniotic sac and amniotic fluid. The placenta connects the fetus to maternal blood supply, ensuring necessary exchanges for fetal growth.
Correct Answer is A
Explanation
Step 1 is: October 17 + 7 days = October 24.
Step 2 is: October 24 - 3 months = July 24.
Step 3 is: July 24 + 1 year = July 24. Answer: July 24 (0724)
