Question 1

A laboring patient at 34 weeks gestation presents with preterm labor. After confirming the diagnosis, which medication would the nurse anticipate giving to promote fetal lung maturity?

Accepted Answer

Betamethasone 12 mg IM given in two doses 24 hours apart

Answer

Betamethasone (a corticosteroid) administered to the mother between 24 and 34 weeks promotes fetal surfactant production and lung maturity, reducing neonatal respiratory distress.

Question 2

What does a Bishop score of 3 indicate in a patient scheduled for labor induction?

Accepted Answer

The cervix is unfavorable and cervical ripening agents are indicated before induction

Answer

A Bishop score of 6 or less (especially ≤3) indicates an unfavorable cervix, and cervical ripening with prostaglandins or a mechanical device is recommended before oxytocin induction.

Question 3

A nurse is preparing to insert an intrauterine pressure catheter (IUPC). Which clinical indication is MOST appropriate for this intervention?

Accepted Answer

There is inadequate tracing quality and the need to assess contraction strength in Montevideo units

Answer

An IUPC is indicated when contraction quality cannot be adequately assessed externally and Montevideo units (MVUs) are needed to determine the adequacy of uterine activity.

Question 4

During delivery, the fetal head is born but the shoulders do not deliver with the next contraction. The nurse recognizes shoulder dystocia and initiates HELPERR. What does the first maneuver 'H' represent?

Accepted Answer

Hyperflexion of maternal thighs (McRoberts maneuver)

Answer

In the HELPERR mnemonic for shoulder dystocia, 'H' stands for McRoberts maneuver — hyperflexing the maternal thighs onto the abdomen to flatten lumbar lordosis and widen the pelvic outlet.

Question 5

A multiparous patient delivers within 2 hours of the onset of regular contractions. Her birth is classified as:

Accepted Answer

Precipitous labor

Answer

Precipitous labor is defined as labor and delivery completed in less than 3 hours from the onset of regular contractions and carries risks of perineal trauma and fetal hypoxia.
