Q1.
A laboring client receiving oxytocin has tachysystole with recurrent late decelerations
despite left lateral positioning and a 500 mL bolus. The provider orders terbutaline 250
mcg subcutaneously. Which physiologic rationale best supports this intervention?
A. Terbutaline increases uterine perfusion by B. Terbutaline is a beta-2 agonist that
selectively dilating the uterine arteries. relaxes uterine smooth muscle, reducing
contraction frequency and restoring
uteroplacental perfusion.
C. Terbutaline accelerates fetal lung maturity D. Terbutaline blocks oxytocin receptors,
by stimulating surfactant release. directly antagonizing the infusion at the
myometrial level.
Correct: B - Terbutaline is a beta-2 agonist that relaxes uterine smooth muscle, reducing
contraction frequency and restoring uteroplacental perfusion.
Rationale:Terbutaline, a beta-2 adrenergic agonist, relaxes myometrial smooth muscle to
reduce contraction frequency and duration, relieving tachysystole and improving
uteroplacental perfusion. It does not dilate uterine arteries, stimulate surfactant, or block
oxytocin receptors (that is atosiban, unavailable in the US).
Q2.
Which finding in a newborn at 12 hours of life most strongly indicates a need for
immediate provider notification rather than routine monitoring?
A. Respiratory rate of 58 breaths/min with B. Apical heart rate of 118 beats/min during
mild substernal retractions that resolve active sleep.
when prone.
C. Central cyanosis of the lips and mucous D. A single episode of emesis after the first
membranes with an SpO2 of 88% on room feeding that is non-bilious.

Correct: C - Central cyanosis of the lips and mucous membranes with an SpO2 of 88% on
room air.

Rationale: Central cyanosis with hypoxemia at 12 hours suggests congenital heart disease or
persistent pulmonary hypertension and requires urgent evaluation. Mild transient retractions,
HR 118, and a single non-bilious emesis are common benign neonatal findings.
Q3.
A postpartum client has a BUBBLE-HE assessment showing a boggy uterus, saturation of
two perineal pads within 15 minutes, and a heart rate increase from 82 to 118. Which initial
action is the priority?
A. Administer methylergonovine 0.2 mg IM B. Perform firm fundal massage and empty
as ordered. the bladder, then reassess.
C. Insert an indwelling urinary catheter and D. Obtain a type and crossmatch and
begin a oxytocin infusion. prepare for blood transfusion.
Correct: B - Perform firm fundal massage and empty the bladder, then reassess.
Rationale:The priority in early postpartum hemorrhage with a boggy uterus is uterine
massage to stimulate contraction and bladder emptying to remove inhibition, the fastest
non-pharmacologic interventions. Methylergonovine is contraindicated in hypertension and is
not first-line before massage; catheterization and transfusion are subsequent steps.
Q4.
A parent reports that their toddler, who was recently started on amoxicillin for otitis
media, now has hives, lip swelling, and audible wheezing. Which medication should the
nurse prepare to administer first?
A. Intramuscular epinephrine 0.01 mg/kg of B. Oral diphenhydramine 1 mg/kg.
1:1000 concentration.
C. Intravenous methylprednisolone 1 mg/kg. D. Nebulized albuterol 2.5 mg.
Correct: A - Intramuscular epinephrine 0.01 mg/kg of 1:1000 concentration.
Rationale:This is anaphylaxis; IM epinephrine is the first-line, life-saving treatment and must
be given before antihistamines, steroids, or beta-agonists. Delaying epinephrine for adjuncts
increases mortality risk.
Q5.
A neonate born at 39 weeks has a maternal history of group B streptococcus positive with
inadequate intrapartum prophylaxis. Which assessment finding most specifically
suggests early-onset GBS sepsis rather than transient tachypnea of the newborn?
A. Grunting and nasal flaring that improve B. Temperature instability, lethargy, and
by 6 hours of life. apnea at 18 hours of life.
