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 ["B","D","F"]

Explanation

Choice A rationale:

Supplementing with formula is not necessary based on the given information. The baby is voiding and passing stools adequately, indicating proper feeding. Instead, feeding on demand and ensuring frequent breastfeeding will help address any concerns about the baby's weight.

Choice B rationale:

Feeding 8 to 12 times per day and on demand is recommended to ensure adequate milk supply and proper growth and development of the newborn. Frequent feeding helps to establish and maintain milk production.

Choice C rationale:

Using plastic-lined breast pads is not recommended as they can trap moisture and create an environment that promotes nipple irritation and infection. It is better to use breathable, non-plastic-lined breast pads.

Choice D rationale:

It is correct that a newborn's stools should transition from the dark greenish color meconium to a yellow color within a few days as the baby begins digesting breast milk.

Choice E rationale:

Drinking more whole milk does not directly increase a mother's milk supply. Milk supply is primarily regulated by the frequency and efficiency of breastfeeding or pumping.

Choice F rationale:

Expecting the breasts to feel full, warm, and slightly tender when the milk comes in is accurate. This usually occurs around the third or fourth day postpartum and indicates that the milk production process is underway.

Correct Answer is A

Explanation

Choice A rationale

Anaphylactoid syndrome of pregnancy (also known as amniotic fluid embolism) occurs when amniotic fluid, fetal cells, hair, or other debris enter the mother's bloodstream, triggering

a serious reaction. It can cause sudden shortness of breath, cardiovascular collapse, and other severe symptoms immediately after a rupture of membranes and is a rare but critical

obstetrical emergency.

Choice B rationale

Abruptio placentae involves the premature separation of the placenta from the uterine wall, which leads to bleeding and potential fetal and maternal distress. However, it does not

typically present with sudden cardiorespiratory collapse or shortness of breath immediately following membrane rupture.

Choice C rationale

Uterine rupture refers to a tear in the wall of the uterus, usually due to trauma, labor stress, or previous surgical scars. While it is a severe condition, it usually presents with

abdominal pain, vaginal bleeding, and fetal distress rather than sudden respiratory failure.

Choice D rationale

Disseminated intravascular coagulation (DIC) is a condition affecting blood clotting processes, often secondary to other conditions like severe preeclampsia, sepsis, or trauma. It

generally presents with bleeding and clotting issues but not sudden respiratory or cardiovascular collapse.
