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 A
Explanation
Choice A rationale
A newborn who is 26 hours post-delivery and has had no urine output needs immediate attention. Lack of urine output for over 24 hours may indicate dehydration or renal issues. Immediate medical evaluation is required to identify underlying conditions and prevent complications such as acute kidney injury or sepsis.
Choice B rationale
Acrocyanosis, characterized by blueish discoloration of the extremities, is common in newborns during the first 24-48 hours of life and usually resolves on its own. It occurs due to immature blood circulation and is generally not a cause for concern.
Choice C rationale
Failure to pass meconium within the first 24 hours can be a sign of conditions like Hirschsprung's disease or cystic fibrosis, but it is not as immediately concerning as anuria (no urine output). Monitoring and further evaluation are necessary, but it does not require urgent provider notification.
Choice D rationale
A blood glucose level of 50 mg/dL in a newborn is within the lower limit of normal. While it's important to monitor, it does not necessitate immediate provider notification unless it continues to drop or other symptoms arise.
