Conception and Fetal Development NCLEX Questions Questions
Question 1 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 2 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.
Question 3 of 5
A nurse is conducting prenatal education classes for a group of expectant parents. Which information should the nurse include in her discussion of the purpose of amniotic fluid? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Cushions the fetus. Amniotic fluid acts as a cushion that protects the fetus from physical trauma and provides a stable environment for fetal growth. It helps prevent compression injuries and maintains a constant temperature. The other choices are incorrect because: B) Protects the skin of the fetus: While amniotic fluid does provide some protection, its main purpose is cushioning. C) Provides nourishment for the fetus: The placenta is responsible for providing nourishment to the fetus, not amniotic fluid. D) Allows for buoyancy for fetal movement: While amniotic fluid does allow for buoyancy, its primary function is to cushion the fetus.
Question 4 of 5
Genomic medicine is an emerging medical discipline that involves using genomic information about an individual as part of the individual’s clinical care. Which example does the nurse associate with genomic medicine?
Correct Answer: A
Rationale: Rationale: A is correct as genomic medicine involves using genetic information for clinical care, such as screening neonates for genetic diseases. This helps in early detection and treatment. B is incorrect as drug development is not the main focus of genomic medicine. C is incorrect as trial studies focus on drug effects, not genetic information. D is incorrect as tracing genetic mutations is related to genetics research, not clinical care in genomic medicine.
Question 5 of 5
A patient at 37 weeks gestation arrives at the labor and delivery unit and reports a rupture of her membranes. Which factor causes the nurse to anticipate the HCP will prescribe a medical method of labor induction?
Correct Answer: A
Rationale: The correct answer is A: The fetus is viable and the barrier for a sterile uterine environment is breached. At 37 weeks gestation, the fetus is considered full-term and capable of surviving outside the womb. Rupture of membranes increases the risk of infection as it exposes the fetus to the vaginal flora. Therefore, a medical method of labor induction may be prescribed to prevent complications such as intrauterine infection. Choices B, C, and D are incorrect: B: The fetus "drying out" and causing a dry birth is not a valid reason for labor induction. C: Bedrest until contractions begin is not a standard approach for managing ruptured membranes. D: While infection risk is a concern with ruptured membranes, the primary reason for induction is to prevent harm to the fetus due to the breach in the sterile uterine environment, not just maternal infection.
