The nurse who is assessing a G2 P1 client palpates the fundal height at the location noted on the picture below (near the umbilicus). The nurse concludes that the fetus is equal to which of the following gestational ages?
16 weeks.
20 weeks.
24 weeks.
28 weeks.
The Correct Answer is B
Choice A rationale
At 16 weeks, the fundal height is typically below the umbilicus. This location is more indicative of a fetus at around 20 weeks.
Choice B rationale
At 20 weeks, the fundal height is usually at the level of the umbilicus, indicating this is the correct gestational age.
Choice C rationale
At 24 weeks, the fundal height is usually above the umbilicus, suggesting a more advanced gestation than the picture indicates.
Choice D rationale
At 28 weeks, the fundal height is significantly above the umbilicus, making this option incorrect for the given scenario.

Correct Answer is C
Explanation
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 ["3.9"]
Explanation
Step 1 is 3900 grams ÷ 1000 = 3.9 kg
Step 2 is 25 mg/kg × 3.9 kg = 97.5 mg
Step 3 is 97.5 mg ÷ (125 mg/5 mL) = 3.9 mL
The newborn will receive 3.9 mL in 24 hours.
