Conception and Fetal Development NCLEX Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse works in a urologist’s office. A male patient is scheduled for routine fertility testing. For which test does the nurse refrain from making preparation?
Correct Answer: C
Rationale: The correct answer is C: Sexual functioning. The nurse should refrain from making preparation for sexual functioning testing because this is not typically part of routine fertility testing. The focus of routine fertility testing for a male patient in a urologist's office would be on assessing sperm health and quality, which includes tests like semen analysis (choice D). STI screening (choice A) may be necessary to rule out any infections that could affect fertility, and hormonal levels (choice B) are important to assess the endocrine system's role in fertility. However, sexual functioning testing is not directly related to assessing fertility issues in this context.
Question 5 of 5
What karyotype would the nurse anticipate for a patient with Klinefelter’s syndrome?
Correct Answer: B
Rationale: The correct answer is B: XXY. In Klinefelter's syndrome, individuals have an extra X chromosome, resulting in a karyotype of 47,XXY. This leads to physical and cognitive characteristics associated with the syndrome. Choice A (XO) represents Turner syndrome, which involves a missing X chromosome. Choices C (XYY) and D (XXX) are not associated with Klinefelter's syndrome as they involve extra Y and X chromosomes respectively, leading to different syndromes altogether.
