Maternity HESI Quizlet

HESI RN

1. One hour after giving birth to an 8-pound infant, a client's lochia rubra has increased from small to large, and her fundus is boggy despite massage. The client's pulse is 84 beats/minute, and blood pressure is 156/96. The healthcare provider prescribes Methergine 0.2 mg IM × 1. What action should the healthcare provider take immediately?

A. Give the medication as prescribed and monitor for efficacy.
B. Encourage the client to breastfeed rather than bottle-feed.
C. Have the client empty her bladder and massage the fundus.
D. Call the healthcare provider to question the prescription.

Correct answer: D

Rationale: The correct action for the healthcare provider to take immediately is to call the healthcare provider to question the prescription. Methergine is contraindicated in clients with hypertension due to its potential to elevate blood pressure further. In this scenario, the client's blood pressure is already elevated at 156/96, making it unsafe to administer Methergine. The LPN/LVN should advocate for the client's safety by questioning the prescription to prevent potential harm.

2. The nurse is caring for a 2-day old neonate who has not passed meconium and has a swollen abdomen. The healthcare provider reviews the flat plate X-ray of the abdomen and makes a tentative diagnosis of Hirschsprung's disease. Which pathophysiological process is consistent with this neonate's clinical picture?

A. The congenital absence of parasympathetic ganglion cells to large intestine produces no peristalsis.
B. Pyloric obstruction causes reflux and projectile hematemesis.
C. Partial imperforated anal opening limits passage of stools.
D. Peristalsis moving against the intestinal obstruction causing hyperactivity of the bowel.

Correct answer: A

Rationale: Hirschsprung's disease is caused by the absence of parasympathetic ganglion cells in the large intestine, leading to a lack of peristalsis and obstruction.

3. A multiparous client is involuntarily pushing while being wheeled into the labor triage area. The nurse observes the fetal head presenting at the perineum. Which action should the nurse take?

A. Support the infant as it emerges.
B. Review prenatal laboratory results.
C. Obtain fetal heart tones.
D. Apply suprapubic pressure.

Correct answer: A

Rationale: When the fetal head is visible at the perineum, the priority is to support the infant's birth to prevent injury. Providing support as the infant emerges helps ensure a safe delivery process and reduces the risk of complications associated with rapid or uncontrolled birth.

4. The LPN/LVN should explain to a 30-year-old gravida client that alpha fetoprotein testing is recommended for which purpose?

A. Detect cardiovascular disorders.
B. Screen for neural tube defects.
C. Monitor placental functioning.
D. Assess for maternal pre-eclampsia.

Correct answer: B

Rationale: The correct answer is B: Screen for neural tube defects. Alpha fetoprotein testing is primarily used to screen for neural tube defects and other fetal abnormalities. It is not used to detect cardiovascular disorders, monitor placental functioning, or assess for maternal pre-eclampsia.

5. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

A. Betamethasone (Celestone).
B. Magnesium sulfate.
C. Terbutaline (Brethine).
D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.
