Conception and Fetal Development NCLEX Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
