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?

A.

The fetal heartbeat can be heard via Doppler by 4 weeks of pregnancy.

B.

The fetal heartbeat can be heard by external Doppler around 10-12 weeks of pregnancy.

C.

You will first feel your baby move in week 24 of pregnancy.

D.

The heart formation begins in week 5 of pregnancy and we can hear it by Doppler at 6 weeks.

Answer and Explanation

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

Decreased deep tendon reflexes are not typically associated with preeclampsia. In fact, hyperreflexia or increased deep tendon reflexes might be observed due to central nervous

system irritability in preeclampsia.

Choice B rationale

Uterine contractions are related to labor and not a specific indicator of preeclampsia. While they might occur simultaneously, they are not diagnostic of preeclampsia.

Choice C rationale

Proteinuria, the presence of excess protein in the urine, is a key diagnostic criterion for preeclampsia. It indicates kidney involvement and is used along with elevated blood pressure to diagnose this condition.

Choice D rationale

Increased blood glucose levels are associated with gestational diabetes rather than preeclampsia. Elevated blood pressure and proteinuria are the hallmarks of preeclampsia.

Correct Answer is A

Explanation

Choice A rationale

Administering antipyretics for maternal fever is essential as elevated maternal temperatures can increase the risk of fetal tachycardia and potentially lead to fetal distress. Reducing

fever promptly is a priority to stabilize both maternal and fetal conditions.

Choice B rationale

Preparing for an emergency cesarean section is not the immediate step for maternal fever; instead, managing the fever and assessing the need for further interventions based on the

overall clinical picture should be prioritized.

Choice C rationale

Administering glucocorticoids is indicated for promoting fetal lung maturity in preterm labor, not specifically for maternal fever management. Fever management requires antipyretics

and hydration.

Choice D rationale

Waiting 4 hours to recheck temperature delays prompt management, increasing risks for both the mother and fetus. Immediate action to reduce fever is crucial to prevent potential

complications.
