HESI Focus on Maternity Exam
1. A newborn with a respiratory rate of 40 breaths per minute at one minute after birth is demonstrating cyanosis of the hands and feet. What action should a nurse take?
- A. Assess bowel sounds.
- B. Continue to monitor.
- C. Assist with intubation.
- D. Rub the infant's back.
Correct answer: B
Rationale: Cyanosis of the hands and feet, known as acrocyanosis, is common in newborns shortly after birth and usually resolves on its own. It is not indicative of a need for immediate intervention. Therefore, the appropriate action is to continue monitoring the newborn's condition. Assessing bowel sounds (Choice A) is not relevant to the presenting issue of cyanosis and respiratory rate. Assisting with intubation (Choice C) is an invasive procedure that is not warranted based on the information provided. Rubbing the infant's back (Choice D) is not necessary for acrocyanosis and could potentially disturb the newborn.
2. What is the process in which the double helix of deoxyribonucleic acid (DNA) duplicates?
- A. Amniocentesis
- B. Mitosis
- C. Meiosis
- D. Mutation
Correct answer: B
Rationale: Mitosis is the correct answer because it is the process of cell division in which a cell duplicates its DNA and divides into two identical daughter cells. During mitosis, the DNA is replicated, and each daughter cell receives an identical copy of the genetic material. Amniocentesis is a medical procedure to collect amniotic fluid for prenatal genetic testing and is not related to DNA duplication. Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell, leading to genetic diversity. Mutation is a permanent alteration in the DNA sequence that can lead to genetic variations but is not the process of DNA duplication.
3. Which FHR finding is the most concerning to the nurse providing care to a laboring client?
- A. Accelerations with fetal movement.
- B. Early decelerations.
- C. Average FHR of 126 beats per minute.
- D. Late decelerations.
Correct answer: D
Rationale: Late decelerations are caused by uteroplacental insufficiency, resulting in fetal hypoxemia. They are considered ominous if persistent, indicating compromised oxygen supply to the fetus. Accelerations with fetal movement (Choice A) are reassuring signs of fetal well-being. Early decelerations (Choice B) are typically benign, associated with head compression during contractions. An average FHR of 126 beats per minute (Choice C) falls within the normal range for fetal heart rate and is not concerning. Therefore, the most concerning FHR finding in a laboring client is late decelerations (Choice D).
4. A client at 38 weeks of gestation has a prescription for intravaginal misoprostol. Which of the following statements should the nurse make?
- A. “You will need to stay in a side-lying position for 30 minutes after each dose.”
- B. “You will receive an IV infusion of oxytocin 1 hour after your last dose.”
- C. “You will receive a magnesium supplement immediately following therapy.”
- D. “You will need to have a full bladder before the therapy begins.”
Correct answer: A
Rationale: The correct answer is A. Instructing the client to stay in a side-lying position after receiving misoprostol intravaginally is essential. This position helps keep the medication in place, allowing for better absorption. Choice B is incorrect because oxytocin administration is not typically indicated after misoprostol use. Choice C is incorrect as magnesium supplementation is not part of the standard protocol for misoprostol administration. Choice D is incorrect as having a full bladder is not necessary before initiating misoprostol therapy.
5. A nurse is caring for an infant who has signs of neonatal abstinence syndrome. Which of the following actions should the nurse take?
- A. Provide a calm environment
- B. Monitor blood glucose levels every hour
- C. Initiate seizure precautions
- D. Place the infant on their back with legs extended
Correct answer: C
Rationale: Initiating seizure precautions is crucial when caring for an infant with neonatal abstinence syndrome due to the increased risk of seizures. Providing a calm environment (Choice A) is important to reduce stimulation as these infants may be irritable. Monitoring blood glucose levels (Choice B) is not typically a priority in neonatal abstinence syndrome unless specific signs or symptoms suggest the need for this assessment. Placing the infant on their back with legs extended (Choice D) does not directly address the potential complications associated with neonatal abstinence syndrome, such as seizures.
