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","B","C"]
Explanation
Choice A rationale: Administer IV fluids with electrolytes: This is crucial to rehydrate the client and correct electrolyte imbalances caused by excessive vomiting, a common complication of hyperemesis gravidarum.
Choice B rationale: Offer small, frequent meals high in protein: Small, frequent meals can help manage nausea and vomiting by preventing the stomach from becoming empty, while high-protein foods can provide necessary nutrients and energy.
Choice C rationale: Administer antiemetics as prescribed: Antiemetics can help control nausea and vomiting, improving the client's ability to tolerate oral intake and maintain hydration and nutrition.
Choice D rationale: Encourage the client to increase oral fluid intake immediately: While increasing oral fluid intake is beneficial, it may not be immediately feasible due to the severity of nausea and vomiting in hyperemesis gravidarum. Hence, initial IV fluid therapy is prioritized.
Choice E rationale: Perform continuous fetal monitoring: Continuous fetal monitoring is not typically necessary in the early stages of pregnancy, especially at 11 weeks of gestation. The primary focus should be on stabilizing the mother's condition to support overall pregnancy health.
Correct Answer is A
Explanation
Choice A rationale
At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.
Choice B rationale
Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.
Choice C rationale
Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.
Choice D rationale
The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.
