1. Why is a client with gestational diabetes being scheduled for an amniocentesis when the fetus has an estimated weight of eight pounds (3629 grams) at 36 weeks gestation? What information is the amniocentesis seeking to obtain?
- A. Presence of a neural tube defect.
- B. Chromosomal abnormalities.
- C. Gender of the fetus.
- D. Fetal lung maturity.
Correct answer: D
Rationale: An amniocentesis in this scenario is most likely being performed to assess fetal lung maturity. This is necessary when considering early delivery due to macrosomia (large fetal size), which is a common concern in gestational diabetes. Evaluating fetal lung maturity is crucial to determine if the fetus's lungs are developed enough to support breathing independently outside the womb. The presence of a neural tube defect and chromosomal abnormalities are not typically assessed through amniocentesis in this situation, and determining the gender of the fetus is not the primary purpose of the procedure here.
2. A client who is receiving prenatal care is at her 24-week appointment. Which of the following laboratory tests should the nurse plan to conduct?
- A. Group B strep culture
- B. 1-hour glucose tolerance test
- C. Rubella titer
- D. Blood type and Rh
Correct answer: B
Rationale: The correct answer is B: 1-hour glucose tolerance test. At around 24-28 weeks of gestation, a pregnant individual is typically screened for gestational diabetes. The 1-hour glucose tolerance test helps in identifying elevated blood sugar levels during pregnancy. Choice A, Group B strep culture, is not typically performed at the 24-week appointment but later in the third trimester to screen for Group B streptococcus colonization. Choice C, Rubella titer, is usually checked early in pregnancy to determine immunity to rubella. Choice D, Blood type and Rh, is important for determining the client's blood type and Rh status, but it is usually done earlier in pregnancy and not specifically at the 24-week appointment.
3. A newborn nursery protocol includes a prescription for ophthalmic erythromycin 5% ointment to both eyes upon a newborn's admission. What action should the nurse take to ensure adequate installation of the ointment?
- A. Instill a thin ribbon into each lower conjunctival sac
- B. Occlude the inner canthus after retracting the eyelids
- C. Mummy wrap the infant before instilling the ointment
- D. Stabilize the instilling hand on the neonate's head
Correct answer: A
Rationale: To ensure adequate installation of the ophthalmic erythromycin 5% ointment in a newborn, the nurse should instill a thin ribbon into each lower conjunctival sac. This method helps to ensure proper distribution and effectiveness of the medication to prevent neonatal conjunctivitis. Choices B, C, and D are incorrect. Occluding the inner canthus after retracting the eyelids, mummy wrapping the infant, or stabilizing the instilling hand on the neonate's head are not appropriate actions for ensuring the proper installation of the ointment.
4. The nurse is caring for a multiparous client who is 8 centimeters dilated, 100% effaced, and the fetal head is at 0 station. The client is shivering and states extreme discomfort with the urge to bear down. Which intervention should the nurse implement?
- A. Administer IV pain medication
- B. Perform a vaginal exam
- C. Reposition to side-lying
- D. Encourage pushing with each contraction
Correct answer: C
Rationale: Repositioning the client to a side-lying position is the most appropriate intervention in this scenario. This position can help relieve pressure on the cervix and reduce the urge to push prematurely, allowing the cervix to continue dilating. Administering IV pain medication may not address the underlying cause of the discomfort, and pushing prematurely can lead to cervical trauma. Performing a vaginal exam is not necessary at this point as the client is already 8 centimeters dilated, and the fetal head is at 0 station.
5. What determines a child’s sex?
- A. Presence of teratogens at the time of conception.
- B. Sex chromosome received from the mother.
- C. Presence of teratogens at the time of ovulation.
- D. Sex chromosome received from the father.
Correct answer: D
Rationale: The correct answer is the sex chromosome received from the father. The father contributes either an X or Y chromosome, which determines the child's sex. This occurs at the moment of fertilization when the sperm carrying either an X (resulting in a female) or Y (resulting in a male) chromosome fertilizes the egg. Choices A, B, and C are incorrect because the presence of teratogens at the time of conception or ovulation does not determine the child's sex. While the sex chromosome received from the mother is important, it is the father's contribution that ultimately determines the child's sex.
