HESI Maternity 55 Questions Quizlet

1. In planning care for a client at 30-weeks gestation experiencing preterm labor, what maternal prescription is most important in preventing this fetus from developing respiratory syndrome?

Correct answer: A

Rationale: The administration of Betamethasone (Celestone) is crucial in cases of preterm labor to promote fetal lung maturation and reduce the risk of respiratory distress syndrome in the newborn. Betamethasone helps enhance the production of surfactant in the fetal lungs, improving their functionality and decreasing the likelihood of respiratory complications upon birth. Butorphanol is an analgesic and not indicated for preventing respiratory syndrome in preterm infants. Ampicillin is an antibiotic used for infection prevention and treatment, not for fetal lung maturation. Terbutaline is a tocolytic agent used to inhibit contractions, but it does not have a direct effect on fetal lung maturity.

2. When can a woman who thinks she may be pregnant use a home pregnancy test to diagnose pregnancy?

Correct answer: A

Rationale: The correct answer is A. Home pregnancy tests detect hCG, a hormone produced during pregnancy, and are most accurate after the first missed period when hCG levels are higher. Testing too early may result in a false negative. Waiting until after the first missed period increases the reliability of the test results. Choice B is incorrect as waiting until after the second missed period is unnecessary and may delay seeking appropriate healthcare. Choice C is incorrect as home pregnancy tests are generally reliable when used correctly. Choice D is incorrect because ovulation occurs before the period, and testing immediately after ovulation may not provide accurate results.

3. How can a nurse make a blind 8-year-old girl admitted to the hospital more comfortable?

Correct answer: A

Rationale: The correct answer is to bring familiar toys from home, such as a bear or doll. This action provides comfort and a sense of security for the child, as it allows her to have familiar objects around her in an unfamiliar environment, which can help reduce anxiety and stress during her hospital stay.

4. While preparing a 10-year-old with a lacerated forehead for suturing, the nurse notices both parents and a 12-year-old sibling at the child’s bedside. Which instruction best supports the family's involvement?

Correct answer: D

Rationale: Involving the family by letting them decide who will stay during the suturing process promotes family engagement and comfort, ensuring the presence of a familiar person for the child during the procedure.

5. While caring for a laboring client on continuous fetal monitoring, the nurse notes a fetal heart rate pattern that falls and rises abruptly with a 'V' shaped appearance. What action should the nurse take first?

Correct answer: A

Rationale: In cases of fetal heart rate patterns showing abrupt falls and rises with a 'V' shaped appearance, it indicates possible cord compression. Changing the maternal position, such as moving the mother onto her side, can relieve the pressure off the cord and help improve fetal oxygenation, making it the priority intervention to address the decelerations.
