HESI Focus on Maternity Exam
1. Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):
- A. zygote.
- B. gonadotrope.
- C. embryo.
- D. chromaffin.
Correct answer: A
Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.
2. A newborn is being assessed by a nurse who was born post-term. Which of the following findings should the nurse expect?
- A. Nails extending over tips of fingers
- B. Large deposits of subcutaneous fat
- C. Pale, translucent skin
- D. Thin covering of fine hair on shoulders and back
Correct answer: A
Rationale: Post-term newborns often have longer nails that extend over the tips of their fingers due to the extended gestation period. This occurs because the baby continues to grow in utero past the typical 40 weeks of gestation. Choices B, C, and D are incorrect as large deposits of subcutaneous fat, pale translucent skin, and a thin covering of fine hair on shoulders and back are not typically associated with post-term newborns. Longer nails are a common finding in post-term newborns due to the prolonged time spent in the womb, allowing for more nail growth compared to infants born at term.
3. A client at 26 weeks gestation was informed this morning that she has an elevated alpha-fetoprotein (AFP) level. After the healthcare provider leaves the room, the client asks what she should do next. What information should the nurse provide?
- A. Reassure the client that the AFP results are likely to be a false reading.
- B. Explain that a sonogram should be scheduled for definitive results.
- C. Inform her that a repeat alpha-fetoprotein (AFP) test should be evaluated.
- D. Discuss options for intrauterine surgical correction of congenital defects.
Correct answer: B
Rationale: An elevated AFP level during pregnancy can indicate potential fetal anomalies. Further evaluation is necessary to confirm the findings and assess the need for additional interventions. Scheduling a sonogram is the appropriate next step as it can provide more definitive results and help identify any underlying issues. Choice A is incorrect because dismissing the elevated AFP level as a false reading without further investigation can lead to missing important information about the baby's health. Choice C is not the best immediate action, as scheduling a sonogram would provide more detailed information than just repeating the AFP test. Choice D is incorrect as discussing intrauterine surgical correction is premature at this stage and not typically indicated based solely on an elevated AFP level.
4. 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.
5. A multiparous woman has been in labor for 8 hours. Her membranes have just ruptured. What is the nurse’s highest priority in this situation?
- A. Prepare the woman for imminent birth.
- B. Notify the woman’s primary healthcare provider.
- C. Document the characteristics of the fluid.
- D. Assess the fetal heart rate (FHR) and pattern.
Correct answer: D
Rationale: The correct answer is to assess the fetal heart rate (FHR) and pattern (Choice D). When a multiparous woman's membranes rupture after 8 hours of labor, the nurse's priority is to assess the fetal well-being. Rupture of membranes can lead to potential complications such as umbilical cord prolapse. Monitoring the fetal heart rate and pattern immediately after the rupture of membranes is crucial to ensure the fetus is not in distress. This assessment helps in determining the need for immediate interventions to safeguard the fetus. Documenting the characteristics of the fluid (Choice C) may be necessary but is of lower priority compared to assessing fetal well-being. While preparing the woman for imminent birth (Choice A) is important, assessing the fetal heart rate takes precedence to ensure the fetus is not compromised. Notifying the woman's primary healthcare provider (Choice B) is also important but not the highest priority at this moment.
