HESI Focus on Maternity Exam
1. Which statement by the client will assist the healthcare provider in determining whether she is in true labor as opposed to false labor?
- A. I passed some thick, pink mucus when I urinated this morning.
- B. My bag of waters just broke.
- C. The contractions in my uterus are getting stronger and closer together.
- D. My baby dropped, and I have to urinate more frequently now.
Correct answer: C
Rationale: The correct answer is C. Regular, strong contractions with the presence of cervical change indicate that the woman is experiencing true labor. Choice A indicates the passing of the mucus plug, which is a sign of early labor but not definitive for true labor. Choice B, the breaking of the bag of waters, is a sign of labor but does not confirm whether it is true or false labor. Choice D, the baby dropping and increased urination frequency, suggests lightening, a sign that labor may be approaching, but it does not confirm true labor.
2. A woman who is 38 weeks gestation is receiving magnesium sulfate for severe preeclampsia. Which assessment finding warrants immediate intervention by the nurse?
- A. Dizziness while standing
- B. Sinus tachycardia
- C. Lower back pain
- D. Absent patellar reflexes
Correct answer: D
Rationale: The correct answer is D: Absent patellar reflexes. Absent patellar reflexes can indicate magnesium toxicity, a serious condition that requires immediate intervention to prevent respiratory depression or cardiac arrest. Dizziness while standing (choice A) is common in pregnancy but does not specifically indicate magnesium toxicity. Sinus tachycardia (choice B) can be a normal response to magnesium sulfate but does not indicate toxicity. Lower back pain (choice C) is common in pregnancy and not specifically associated with magnesium toxicity.
3. Examination reveals that the laboring client's cervix is dilated to 2 centimeters, 70% effaced with the presenting part at -2 station. The client tells the nurse, 'I need my epidural now, this hurts.' The nurse's response to the client is based on which information?
- A. The client will need to be catheterized before the epidural can be administered.
- B. Administering an epidural at this point would slow down the labor process.
- C. The client should be dilated to at least 8 centimeters before receiving an epidural.
- D. The baby needs to be at a zero station before an epidural can be administered.
Correct answer: B
Rationale: Administering an epidural too early in labor, especially at 2 cm dilation, can slow down the progress of labor. It is usually recommended to wait until labor is more established. Choice A is incorrect because catheterization is not a prerequisite for epidural administration. Choice C is incorrect as waiting until 8 cm dilation is not a standard requirement for epidural administration. Choice D is incorrect because the baby's station being at zero is not a strict criterion for epidural administration.
4. In the prenatal record, the nurse should record for the pregnant client who has a 3-year-old child at home, a term birth, a miscarriage at 10 weeks’ gestation, and a set of twins who died within 24 hours:
- A. Gravida 2, para 1.
- B. Gravida 3, para 3.
- C. Gravida 4, para 2.
- D. Gravida 5, para 4.
Correct answer: C
Rationale: The correct answer is C: 'Gravida 4, para 2.' Gravida refers to the total number of pregnancies, including the current one. In this case, the client has been pregnant a total of 4 times, so gravida is 4. Para is the number of pregnancies that have reached viability, which is 2 in this case. The client has had a term birth and a set of twins who died within 24 hours, totaling 2 pregnancies that reached viability. Choices A, B, and D are incorrect because they do not accurately reflect the client's obstetric history based on the information provided.
5. Following a traumatic delivery, an infant receives an initial Apgar score of 3. Which intervention is most important for the nurse to implement?
- A. Page the pediatrician STAT
- B. Continue resuscitative efforts
- C. Repeat the Apgar assessment in 5 minutes
- D. Inform the parents of the infant's condition
Correct answer: B
Rationale: In a situation where an infant receives a low Apgar score of 3 following a traumatic delivery, the most crucial intervention for the nurse to implement is to continue resuscitative efforts. A low Apgar score indicates that the newborn is in distress and requires immediate medical attention to support breathing, heart rate, muscle tone, reflex irritability, and color. Continuing resuscitative efforts is essential to provide life-saving interventions promptly. Paging the pediatrician may cause a delay in crucial interventions, repeating the Apgar assessment in 5 minutes is not appropriate as immediate action is needed to stabilize the infant, and informing parents should not take precedence over providing immediate medical care to the newborn.
