HESI Focus on Maternity Exam Questions
Question 1 of 5
What is the highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy?
Correct Answer: A
Rationale: The highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy is to assess the fetal heart rate (FHR) and maternal vital signs. This assessment is crucial in determining the extent of blood loss and its impact on both the mother and the fetus. Ensuring the well-being of both the mother and the fetus is the top priority in this situation. While obtaining hemoglobin and hematocrit levels is important, it can be done after the initial assessment. Placing clean disposable pads is necessary for managing any drainage but does not take precedence over assessing vital signs. Monitoring uterine contractions is important but is not the highest priority when compared to assessing the FHR and maternal vital signs.
Question 2 of 5
A charge nurse is teaching a group of staff nurses about fetal monitoring during labor. Which of the following findings should the charge nurse instruct the staff members to report to the provider?
Correct Answer: A
Rationale: The correct answer is A. Contraction durations of 95 to 100 seconds are prolonged, indicating uterine hyperstimulation, which can lead to fetal distress and requires immediate intervention. Reporting this finding to the provider is crucial to ensure timely management and prevent adverse outcomes.
Choice B, contraction frequency of 2 to 3 minutes apart, is within the normal range and does not raise immediate concerns.
Choice C, absent early deceleration of fetal heart rate, is a reassuring finding suggesting fetal well-being.
Choice D, a fetal heart rate of 140/min, is also normal for a fetus and does not typically require immediate reporting unless it deviates significantly from the baseline or is accompanied by other concerning signs.
Question 3 of 5
A client who delivered a healthy newborn an hour ago asked the nurse when she can go home. Which information is most important for the nurse to provide the client?
Correct Answer: D
Rationale: The most critical information for the nurse to provide the client is ensuring that there is no significant vaginal bleeding before discharge. This is vital to prevent complications such as postpartum hemorrhage. Options A, B, and C are important aspects of postpartum care, but assessing and managing vaginal bleeding takes precedence due to its potential seriousness.
Question 4 of 5
Dizygotic (DZ) twins share _________ percent of their genes.
Correct Answer: C
Rationale: Dizygotic (DZ) twins share approximately 50% of their genes. This is because dizygotic twins, also known as fraternal twins, originate from two separate fertilized eggs and share similar genetic similarity to regular siblings.
Choice A (100%) is incorrect because if twins shared 100% of their genes, they would be identical twins (monozygotic).
Choice B (75%) is incorrect as it is not the typical genetic similarity seen in dizygotic twins.
Choice D (25%) is incorrect as it represents a significantly lower genetic similarity than what is observed in dizygotic twins.
Question 5 of 5
Twenty-year-old Jack is extremely tall and has very thick facial hair. Most of his male secondary sex characteristics are also more pronounced than men of his age. In this scenario, Jack is most likely:
Correct Answer: A
Rationale: The correct answer is A: an XYY male. Individuals with XYY syndrome often exhibit increased height and more pronounced secondary male characteristics, such as thick facial hair.
Choice B, Klinefelter syndrome (XXY), typically presents with less prominent male secondary sex characteristics due to the presence of an extra X chromosome.
Choice C, XXY male, refers to Klinefelter syndrome, which does not align with the description of Jack having more pronounced male secondary sex characteristics.
Choice D, Down syndrome, is caused by a trisomy of chromosome 21 and is not associated with the physical characteristics described in the scenario.
