HESI Maternity 55 Questions

1. After meiosis, each new cell nucleus contains _____ chromosomes.

Correct answer: C

Rationale: After meiosis, each resulting cell contains 23 chromosomes. Meiosis is a process that involves two sequential divisions resulting in four daughter cells, each with half the number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes (diploid), and after meiosis, the resulting cells (sperm or ova) have 23 chromosomes (haploid). Choice A (46 chromosomes) is incorrect because this is the number of chromosomes in a human diploid cell before meiosis. Choices B (35 chromosomes) and D (12 chromosomes) are incorrect as they do not represent the correct number of chromosomes after meiosis in human cells.

2. Which of the following statements about Rh incompatibility is true?

Correct answer: D

Rationale: Rh incompatibility occurs when the mother's antibodies attack the fetus's red blood cells, leading to serious complications, usually in subsequent pregnancies. Choice A is incorrect because Rh incompatibility often occurs in subsequent pregnancies, not necessarily the first one. Choice B is incorrect as Rh incompatibility does not render a woman infertile but can lead to complications during pregnancies. Choice C is incorrect as Rh incompatibility is not carried by a sex chromosome but involves the Rh factor on red blood cells.

3. Four clients at full term present to the labor and delivery unit at the same time. Which client should a nurse assess first?

Correct answer: C

Rationale: A primipara with vaginal show and leaking membranes requires immediate assessment as she may be in active labor or at risk of infection. The vaginal show and leaking membranes suggest potential rupture of membranes and the start of labor. Assessing her first ensures prompt management and monitoring. The other options, while important, do not indicate immediate or emergent needs. Contractions every three minutes in a multipara can be managed with ongoing monitoring; non-stress tests and biophysical profiles can be scheduled and are not acute needs. Burning on urination and urinary frequency in a primipara may indicate a urinary tract infection, which is important but not as urgent as assessing for active labor or rupture of membranes.

4. A client at 38 weeks of gestation has a prescription for intravaginal misoprostol. Which of the following statements should the nurse make?

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 client at 30 weeks gestation reports that she has not felt the baby move in the last 24 hours. Concerned, she arrives in a panic at the obstetric clinic where she is immediately sent to the hospital. Which assessment warrants immediate intervention by the nurse?

Correct answer: A

Rationale: A fetal heart rate of 60 beats per minute is significantly below the normal range (110-160 bpm) and indicates fetal distress, requiring immediate intervention. This low heart rate can be a sign of fetal compromise or distress, necessitating urgent evaluation and intervention to ensure the well-being of the fetus. Choices B, C, and D do not indicate immediate fetal distress requiring urgent intervention. Ruptured amniotic membrane, onset of uterine contractions, and leaking amniotic fluid are important assessments but do not present an immediate threat to the fetus's life like a severely low fetal heart rate.
