Inpatient OB Exam Review with
Complete solutions
A 32-week gestation client presents to the unit with complaint of "my water just broke."
She denies having any contractions. Her prenatal record reveals she has a vasa previa.
The nurse anticipates:
An antihypertensive category that is contraindicated during the second and third
trimester of pregnancy is:
Ace inhibitors
Beta blockers
Calcium channel blockers
Thiazides - ANS-Ace inhibitors
RATIONALE: Angiotensin-converting enzyme (ACE) inhibitors and angiotensin blocking
agents (ARBs) are associated with reduced blood flow to the fetal kidneys, renal
agenesis/dysgenesis, oligohydramnios, calvarial and pulmonary hypoplasia, intrauterine
growth restriction, neonatal renal failure and fetal death.
An umbilical cord blood gas (artery) on a term neonate reveals the following: pH 7.29
pCO2: 47 mmHg HCO3: 23 mEq/L This blood gas indicates:
- The neonate is in a balanced acid-base state
- These values represent metabolic acidosis
- These values indicate respiratory acidosis
- These values indicate respiratory alkalosis - ANS-The neonate is in a balanced acid-
base state
At 32 weeks, a prenatal patient reported decreased fetal movement. A non-stress test is
reported as non-reactive. Which of the following is appropriate for this patient?
Induction of labor
Biophysical profile (BPP)
Contraction stress test (CST)
Amniocentesis - ANS-Biophysical profile (BPP)
BPP measures fetal tone, movement, breathing rate, and amniotic fluid.
, During labor, a woman in pain complains of dizziness, light-headedness, and numbness
and tingling in her lips. The MOST LIKELY cause of these symptoms is: - ANS-
Hyperventilation
During pregnancy, which of the following foods should the woman avoid? - ANS-Raw
meat and uncooked shellfish
RATIONALE:
toxoplasmosis, a parasitic infection which can be transmitted to the fetus and which may
lead to miscarriage. Raw shellfish may have high levels of mercury which can affect
fetal CNS development.
Listeria is another contaminant that may be found in raw or undercooked foods and can
lead to miscarriage, fetal demise, or severe illness in the newborn.
During the second stage of labor, the cardinal movement of restitution describes: - ANS-
Rotation of the fetal head 45 degrees after head delivery
RATIONALE: Restitution is the movement of the baby's head from face-down to facing
sideways in order for the shoulders to fit under the maternal pubic arch.
Following delivery, the mother is found to be in the taking-in phase. Which of the
following behaviors would the nurse expect to see in a mother in the taking-in phase of
maternal role adaptation:
Gaining self-confidence
Adjusting to her new relationships
Being passive and dependent
Resuming control over her life - ANS-Being passive and dependent
RATIONALE: Reba Rubin (1984) described the taking-in maternal role adaptation
phase. She described the mother as being passive and dependent on others the first 24
hours after delivery.
In the low-risk patient who is in the active stage of labor and being monitored
electronically, the fetal heart should be assessed every: - ANS-30 minutes
One theory of labor initiation is an increase in:
Follicular stimulating hormone (FSH)
Progesterone
Prostacyclin
Estrogen - ANS-Estrogen
