HESI Focus on Maternity Exam
1. The healthcare provider is planning care for a client at 30 weeks gestation who is experiencing preterm labor. Which medication is most important in preventing this fetus from developing respiratory distress syndrome?
- A. Ampicillin 1 gram IV push every 8 hours
- B. Betamethasone 12 mg deep IM
- C. Terbutaline 0.25 mg subcutaneously every 15 minutes for 3 doses
- D. Butorphanol tartrate 1 mg IV push every 2 hours as needed
Correct answer: B
Rationale: Betamethasone is a corticosteroid given to stimulate fetal lung maturity and reduce the risk of respiratory distress syndrome in preterm infants. Ampicillin (Choice A) is an antibiotic and does not prevent respiratory distress syndrome. Terbutaline (Choice C) is a tocolytic used to inhibit contractions and does not directly prevent respiratory distress syndrome. Butorphanol tartrate (Choice D) is an opioid analgesic and does not have a role in preventing respiratory distress syndrome in preterm infants.
2. The mother of a breastfeeding 24-hour old infant is very concerned about the techniques involved in breastfeeding. She calls the nurse with each feeding to seek reassurance that she is doing it right. She tells the nurse, "Now my daughter is not getting enough to eat." Which response would be best for the nurse to make?
- A. Feed your baby hourly until you feel confident that your child is receiving enough milk.
- B. Don't worry, soon your milk will come in, and you will feel how full your breasts are.
- C. Since you are so concerned, you should probably supplement breastfeeding with formula.
- D. If your baby's urine is straw-colored, she's getting enough milk.
Correct answer: D
Rationale: Reassuring the mother that the baby's urine color can be an indicator of adequate hydration can help her feel more confident in her breastfeeding.
3. A newborn is 1 hour old with a respiratory rate of 50/min, a heart rate of 130/min, and an axillary temperature of 36.1°C (97°F). Which of the following actions should be taken?
- A. Give the newborn a warm bath.
- B. Apply a cap to the newborn's head.
- C. Reposition the newborn.
- D. Obtain an oxygen saturation level.
Correct answer: B
Rationale: Applying a cap to the newborn's head is the correct action in this scenario. Newborns are at risk of heat loss due to their high surface area to volume ratio, and maintaining their body temperature is crucial to prevent hypothermia. Giving a warm bath can further increase heat loss and is not recommended. Repositioning the newborn may not address the primary concern of temperature regulation. While monitoring oxygen saturation is important, addressing thermal regulation takes precedence in this situation.
4. The nurse is planning discharge teaching for four mothers. Which postpartum client is at highest risk for psychological difficulties during the postpartum period?
- A. A primiparous woman who has recently migrated to the US with her spouse
- B. A multiparous client who lives with her husband and his family members
- C. A multiparous female with a large family living in a community
- D. A primiparous adolescent living at home with her parents and significant other
Correct answer: A
Rationale: A primiparous woman who has recently migrated to the US with her spouse is at the highest risk for psychological difficulties during the postpartum period. Recent migration and adjustment to a new environment can increase the risk of postpartum depression, especially when combined with the challenges of being a new mother. Choice B, a multiparous client living with her husband and his family, may have social support from family members, which can be protective against psychological difficulties. Choice C, a multiparous female with a large family living in a community, also indicates potential social support. Choice D, a primiparous adolescent living at home with her parents and significant other, may have a support system in place with her family and significant other.
5. Chromosomes contain thousands of segments called:
- A. nuclei.
- B. nodes.
- C. capillaries.
- D. genes.
Correct answer: D
Rationale: Chromosomes are structures composed of DNA and genes. Genes are the functional segments within chromosomes that encode specific traits and characteristics. The other choices ('nuclei,' 'nodes,' 'capillaries') do not accurately describe the segments found within chromosomes and are unrelated to their structure or function.
