Conception and Fetal Development NCLEX Questions Questions
Question 1 of 5
With regard to the development of the respiratory system, maternity nurses should understand that:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
An expectant father asks the nurse, “Which part of the mature sperm contains the male chromosome?” What is the correct response by the nurse?
Correct Answer: C
Rationale: The correct response is C: The head of the sperm. The head of the sperm contains the genetic material, including the male chromosome (Y chromosome). This is where the genetic information determining the sex of the offspring is located. The tail of the sperm is responsible for movement, not genetic material. X-bearing sperm would contain the female chromosome, not the male chromosome. The middle portion of the sperm does not specifically contain the genetic material related to determining the sex of the offspring.
Question 3 of 5
The upper uterus is the best place for the fertilized ovum to implant due to which anatomical adaptation?
Correct Answer: D
Rationale: The correct answer is D because the upper uterus provides the developing baby with the best nourishment due to increased blood flow and nutrient supply. This area allows for optimal growth and development of the fetus. Maternal blood flow is higher in the upper uterus, not lower (A). While the placenta attaches firmly in the upper uterus, it is not the main reason for the implantation site (B). The uterine endometrium is softer in the lower uterus, not the upper, making choice C incorrect. In summary, the upper uterus is ideal for implantation due to increased nourishment for the developing baby, making choice D the correct answer.
Question 4 of 5
An expectant mother, diagnosed with oligohydramnios, asks the nurse what this condition means for the baby. Which statement should the nurse provide for the patient?
Correct Answer: A
Rationale: The correct answer is A: Oligohydramnios can cause poor fetal lung development. Oligohydramnios refers to a condition where there is a decreased amount of amniotic fluid surrounding the fetus. This can result in compression of the fetus leading to poor lung development. Reduced amniotic fluid levels can also increase the risk of umbilical cord compression and fetal growth restriction. Option B is incorrect as oligohydramnios actually indicates a decreased production of amniotic fluid, not excessive urine excretion by the fetus. Option C is incorrect as oligohydramnios is not directly related to gastrointestinal blockage in the fetus. Option D is incorrect as oligohydramnios is primarily associated with fetal lung and renal abnormalities, not central nervous system abnormalities.
Question 5 of 5
Which physical characteristics decrease as the fetus nears term? (Select all that apply.)
Correct Answer: A
Rationale: Vernix caseosa is a protective, waxy substance on the fetus' skin that decreases as the fetus nears term due to absorption into the skin. Lanugo, fine hair that covers the fetus, persists until birth. Port wine stain, a birthmark, and brown fat, a specialized fat for newborns' warmth, do not decrease as the fetus nears term.
