A father asks the nurse how the baby can exist in fluid for so long without resulting in some harmful effects on the skin.
The nurse's best reply would be:
A soft lanugo hair protects the skin from exposure to the amniotic fluid.
We will apply cream to the baby's skin after delivery to make it smooth and soft.
The baby's skin is covered with a protective fatty substance called vernix caseosa.
There is a thick layer of subcutaneous fat on the baby so the water doesn't harm the skin.
The Correct Answer is C
Choice A rationale
Lanugo is a fine hair that covers the fetus but does not primarily protect the skin from amniotic fluid exposure. It mainly helps in thermoregulation and the adherence of the vernix caseosa.
Choice B rationale
While skin care after birth is important, applying cream post-delivery does not explain why the skin is protected during gestation.
Choice C rationale
Vernix caseosa is a protective, cheese-like coating that covers the fetus's skin. It provides a barrier against the amniotic fluid, preventing maceration of the skin during the pregnancy.
Choice D rationale
Although subcutaneous fat develops in the fetus, it is not responsible for protecting the skin from amniotic fluid. The primary protective mechanism is the vernix caseosa.

Correct Answer is A
Explanation
Choice A rationale
Ambivalent feelings are common in early pregnancy due to hormonal changes and the significant life adjustments that accompany pregnancy. It is normal for pregnant women to experience mixed emotions as they adapt to the reality of impending parenthood.
Choice B rationale
Suggesting the client speak to her mother about these feelings may not be appropriate as it could dismiss the client's current feelings and needs. While family support is valuable, the nurse should first address the client's concerns directly.
Choice C rationale
Referring the client to a counselor may be necessary in some cases, but it is essential to first normalize the client's feelings. It helps in providing immediate reassurance and understanding before suggesting further intervention.
Choice D rationale
Telling the client "Don't worry, you will be fine once the baby is born" is dismissive and minimizes her current concerns. It is important to validate her feelings and provide supportive responses to help her cope with her emotions.
Correct Answer is D
Explanation
Choice A rationale
The fetal heartbeat can be heard with a Doppler at the fourth week of gestation is incorrect. At this early stage, the embryonic heart has only just begun to form, and its activity cannot be detected by Doppler.
Choice B rationale
The fetal heartbeat can be heard with a Doppler at the sixth week of gestation is incorrect. Although the heart begins to beat around this time, it is usually too faint to be detected by Doppler.
Choice C rationale
The fetal heartbeat can be heard with a Doppler at the seventh week of gestation is incorrect. It remains challenging to detect the fetal heartbeat this early with standard Doppler equipment.
Choice D rationale
The fetal heartbeat can be heard with a Doppler at the twelfth week of gestation is correct. By the end of the first trimester, the fetal heart is sufficiently developed and strong enough to be detected using Doppler ultrasound, allowing healthcare providers to monitor fetal well-being.
