Question 1
A laboring patient’s fetal heart rate monitor notes a sudden drop below the baseline that
occurs rapidly, looks like a sharp "V" shape, and does not align with uterine
contractions. What is the primary cause of this deceleration pattern?
A) Fetal head compression during a contraction
B) Umbilical cord compression
C) Uteroplacental insufficiency
D) Maternal hyperthermia
Answer: B) Umbilical cord compression
Rationale: Variable decelerations are defined by a rapid drop below baseline with a
sharp, angular visual profile resembling a "V", "U", or "W" shape. They are caused
strictly by mechanical umbilical cord compression, requiring immediate patient position
shifts to relieve pressure.
Question 2
A nurse notes late decelerations on a fetal heart rate monitor strip during active labor.
Which physiological breakdown causes this specific deceleration pattern?
A) Fetal head compression against the pelvic floor
B) Uteroplacental insufficiency
C) Umbilical vein occlusion from a tight cord knot
D) Maternal hypotonic uterine dysfunction
Answer: B) Uteroplacental insufficiency
Rationale: Late decelerations feature a gradual decrease and return of the fetal heart
rate baseline that begins after the peak of a contraction. This pattern indicates
uteroplacental insufficiency, which compromises fetal oxygenation during uterine
contractions.
,Question 3
A laboring patient is experiencing consistent late decelerations on the fetal monitor.
Which intervention must the nurse execute first?
A) Instruct the patient to perform deep valsalva pushing.
B) Reposition the patient to a lateral side-lying position.
C) Increase the primary intravenous Oxytocin infusion rate.
D) Prepare immediate instrumentation for a low-vacuum delivery.
Answer: B) Reposition the patient to a lateral side-lying position.
Rationale: Late decelerations require immediate intrauterine resuscitation.
Repositioning the patient to a lateral (preferably left) side-lying position removes uterine
weight from the vena cava, boosting maternal venous return, cardiac output, and
placental perfusion.
Question 4
A fetal heart rate monitor strip displays early decelerations that mirror the starting,
peaking, and ending points of the mother's uterine contractions. What is the correct
nursing action for this pattern?
A) Discontinue the Oxytocin infusion immediately.
B) Administer oxygen at 10 L/min via a non-rebreather mask.
C) Continue normal monitoring as this is a benign finding.
D) Place the patient in a steep Trendelenburg position.
Answer: C) Continue normal monitoring as this is a benign finding.
Rationale: Early decelerations result from mechanical fetal head compression during a
contraction, which triggers a transient vagal response. This is a benign, non-
pathological finding that requires no corrective medical intervention.
Question 5
A postpartum patient who delivered 4 hours ago is experiencing heavy vaginal bleeding.
Palpation reveals a soft, boggy, non-contracted fundus located 2 cm above the
umbilicus. Which action should the nurse perform first?
A) Notify the on-call obstetric provider immediately.
B) Catheterize the bladder to assess for urinary retention.
C) Perform aggressive fundal massage until the uterus firms up.
D) Insert a secondary large-bore intravenous line.
Answer: C) Perform aggressive fundal massage until the uterus firms up.
Rationale: Uterine atony is the leading cause of early postpartum hemorrhage (PPH)
,within the first 24 hours. The immediate priority is external fundal massage to stimulate
myometrial contractions and close the bleeding spiral arteries.
Question 6
During a postpartum assessment 6 hours after birth, the nurse notes that the patient's
fundus is firm but deviated to the right side of the abdomen and located above the
umbilicus. What is the cause of this finding?
A) Uterine atony from prolonged labor induction
B) Retention of thick placental tissue fragments
C) A distended, full bladder
D) Localized broad ligament hematoma
Answer: C) A distended, full bladder
Rationale: A postpartum fundus that is high and deviated to the right is the hallmark
indicator of a distended, full bladder. A full bladder physically displaces the uterus
upward and laterally, interfering with uterine contraction and increasing hemorrhage
risks.
Question 7
A postpartum mother who is formula feeding her infant asks the nurse how to manage
breast engorgement discomfort. Which instruction should the nurse provide?
A) Pump the breasts every two hours to clear stagnant milk.
B) Wear a tight, supportive sports bra continuously and apply cold ice packs.
C) Let warm water strike the breasts directly during a shower.
D) Manually express small volumes of milk when pain peaks.
Answer: B) Wear a tight, supportive sports bra continuously and apply cold ice
packs.
Rationale: For formula-feeding mothers, lactation suppression is achieved by avoiding
all forms of nipple stimulation. The nurse should recommend a snug, supportive sports
bra, cold ice packs, and avoiding warm water streams on the chest to dry up milk
production.
Question 8
A patient with severe preeclampsia is receiving a continuous intravenous infusion of
Magnesium Sulfate for seizure prophylaxis. Which finding indicates localized
magnesium toxicity?
A) Hyperactive deep tendon reflexes (+4) with sustained clonus
B) Absent deep tendon reflexes and a respiratory rate of 10 breaths/min
, C) A sudden spike in core maternal temperature to 101°F
D) Total urine output measuring 50 mL over the last hour
Answer: B) Absent deep tendon reflexes and a respiratory rate of 10 breaths/min
Rationale: Magnesium Sulfate is a central nervous system depressant. Signs of clinical
toxicity include the loss of deep tendon reflexes (DTRs), respiratory depression (\(<12
\text{ breaths/min}\)), and a drop in urine output.
Question 9
A nurse identifies signs of severe Magnesium Sulfate toxicity in a preeclamptic patient.
Which medication must the nurse prepare to administer immediately?
A) Naloxone
B) Terbutaline Sulfate
C) Calcium Gluconate
D) Protamine Sulfate
Answer: C) Calcium Gluconate
Rationale: Calcium Gluconate is the direct physiological antidote for Magnesium Sulfate
toxicity. It works by antagonizing the neuromuscular blocking effects of excess
magnesium ions.
Question 10
A postpartum patient who received a Magnesium Sulfate infusion for preeclampsia
during labor is at an increased risk for which postpartum complication?
A) Precipitous bowel elimination
B) Postpartum hemorrhage from uterine atony
C) Premature mastitis infection
D) Pathological deep vein thrombosis
Answer: B) Postpartum hemorrhage from uterine atony
Rationale: Magnesium Sulfate acts as a smooth muscle relaxant. This pharmacological
action directly relaxes the myometrium, placing the postpartum patient at a significantly
higher risk for uterine atony and hemorrhage.
Question 11
A nurse is assessing a newborn 15 minutes after birth. Which finding represents an
operational sign of neonatal respiratory distress?
A) Irregular breathing pattern with short pauses under 10 seconds
B) Acrocyanosis noted on the hands and feet surfaces
