Identify the birthing place providing the most comprehensive labor, birth, and immediate postpartum and newborn care.

  • A. hospital with LDRP and NICU units
  • B. in-hospital birthing center
  • C. free-standing birthing center
  • D. home birth
Correct Answer: A

Rationale: The correct answer is A: hospital with LDRP and NICU units. Hospitals with Labor-Delivery-Recovery-Postpartum (LDRP) and Neonatal Intensive Care Unit (NICU) provide the most comprehensive care for labor, birth, and immediate postpartum and newborn care. LDRP units allow women to stay in one room for the entire birthing process, ensuring continuity of care. The NICU is crucial for providing specialized care to newborns with complications. In-hospital birthing centers lack the full range of medical resources available in hospitals, free-standing birthing centers may not have immediate access to emergency care, and home births carry risks due to limited medical interventions available.

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?

  • A. Screening of neonates for inherited, treatable genetic diseases
  • B. Creating drugs specifically for the treatment of cancer
  • C. Conducting trial studies to determine how drugs effect individuals
  • D. Tracing and gaining knowledge about how genetic mutations occur
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.

Match each term with its description. Blastocyst

  • A. None
  • B. None
  • C. Part of the blastocyst that will develop into the placenta.
  • D. None
Correct Answer: C

Rationale: Blastocyst contains structures forming the placenta.

A woman asks the nurse, 'What protects my baby's umbilical cord from being squashed while the baby's inside of me?' The nurse's best response is:

  • A. Your baby's umbilical cord is surrounded by connective tissue called Wharton jelly, which prevents compression of the blood vessels and ensures continued nourishment of your baby.
  • B. Your baby's umbilical floats around in blood anyway.
  • C. You don't need to worry about things like that.
  • D. The umbilical cord is a group of blood vessels that are very well protected by the placenta.
Correct Answer: A

Rationale: Wharton jelly surrounds the umbilical cord and prevents compression of the blood vessels.

What karyotype would the nurse anticipate for a patient with Klinefelter’s syndrome?

  • A. XO
  • B. XXY
  • C. XYY
  • D. XXX
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.

What is the hormone responsible for the maintenance of the endometrium during pregnancy and the maturation of mammary gland tissue?

  • A. Estrogen
  • B. Human chorionic gonadotropin (hCG)
  • C. Prolactin
  • D. Progesterone
Correct Answer: D

Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining the endometrium during pregnancy by promoting its growth and preventing contractions. It also plays a crucial role in preparing the mammary glands for lactation. Estrogen (A) is important in the menstrual cycle but not specifically for maintaining the endometrium during pregnancy. Human chorionic gonadotropin (hCG) (B) is produced by the placenta and is primarily involved in supporting pregnancy and detecting pregnancy tests. Prolactin (C) is responsible for milk production but is not directly related to the maintenance of the endometrium or mammary gland tissue during pregnancy.
