According to the March of Dimes, there may be four main routes to spontaneous premature labor.
They include all except which of the following?
a. infections or inflammation
b. maternal or fetal stress
c. diabetes
d. bleeding - CORRECT ANSWER-c. diabetes
Diabetes is not a route considered. The fourth route is uterine stretching. Overdistention of the
uterus due to multiple gestation, or placental abnormalities can lead to the release of chemicals that
stimulate uterine contractions.
The presence of 10^5 or more bacterial colonies per milliliter of urine on two consecutive, clean
catch, midstream voided specimens is an indication of:
a. pyelonephritis
b. cystitis
c. thrombophlebitis
d. bacteriuria - CORRECT ANSWER-d. bacteriuria
Bacteriuria is defined as the presence of 10^5 or more bacterial colonies per milliliter of urine on
two consecutive, clean catch, midstream voided specimens. Risk is associated with sickle cell trait,
lower socio-economic status, increased parity, and reduced availability of medical care.
A marked danger of aspiration in the preterm newborn exists due to all but which of the following?
a. poorly developed gag reflex
,b. poor sucking reflex
c. poor swallowing reflex
d. small stomach capacity - CORRECT ANSWER-d. small stomach capacity
A small stomach capacity is not a reason for aspiration in the preterm newborn. Difficulty in meeting
high caloric and fluid needs for growth is due to small stomach capacity. An incompetent esophageal
cardiac sphincter is also a factor in the danger of aspiration in the preterm newborn.
A blood loss of 1500-2000 mL from postpartum hemorrhage (PPH) would be considered which of the
following?
a. mild
b. moderate
c. severe
d. compensated - CORRECT ANSWER-b. moderate
Moderate postpartum hemorrhage also includes HR > 120 bpm, systolic blood pressure of 70-80
mmHg, tachypnea, urine output of 5-20 mL/hr, restlessness, pallor, and confusion.
You are measuring the heart rate of a newborn female. When you measure her resting heart rate,
the average beats per minute should fall into which of the following ranges?
a. 60-110
b. 80-140
c. 120-180
d. 60-115 - CORRECT ANSWER-c. 120-180
Which of the following is NOT a single-gene disorder?
a. Tay-Sachs disease
b. cystic fibrosis
c. Trisomy 18
d. hemophilia A - CORRECT ANSWER-c. Trisomy 18
Trisomy 18, or Edwards syndrome, results from a chromosome abnormality. The other three choice
are single-gene (Mendelian) disorders.
Whitish-yellow cysts containing epithelial cells may be present on the hard palate at birth. These are
called
,a. nevus simplex
b. Epstein's pearls
c. milia
d. thrush - CORRECT ANSWER-b. Epstein's pearls
Epstein's pearls disappear within a few weeks.
Which of the following statements about ABO incompatibility is accurate?
a. ABO incompatibility is uncommon in preterm infants
b. ABO incompatibility becomes more severe in further pregnancies
c. ABO incompatibility cannot occur in first-born babies
d. Significant problems with ABO incompatibility occur mostly with babies whose mothers have O
blood type and the baby has either A or B blood type - CORRECT ANSWER-d. Significant problems
with ABO incompatibility occur mostly with babies whose mothers have O blood type and the baby
has either A or B blood type
ABO incompatibility is a common and generally mild type of hemolytic disease in babies. Premature
babies are much more likely to experience severe problems with ABO incompatibility. Unlike
hemolytic disease that can result in subsequent babies when a mother has a negative blood group,
ABO incompatibility can occur in first-born babies and does not become more severe in further
pregnancies.
Which of the following is least likely to be a risk factor for postpartum hemorrhage?
a. augmented labor
b. slow labor
c. preeclampsia
d. Asian ethnicity - CORRECT ANSWER-b. slow labor
Rapid labor rather than slow labor is a risk factor for postpartum hemorrhage. Other risk factors
include a history of postpartum hemorrhage, episiotomy (especially mediolateral), overdistended
uterus, chorioamnionitis, and operative delivery.
Anatomical closure of the foramen ovale occurs by
a. one hour
b. one day
c. one month
d. one year - CORRECT ANSWER-d. one year
, Following increased lung perfusion at birth, the pressures in the two atria equalize causing the
foramen ovale valve to close. This closure is functional and a patent foramen ovale may persist until
pressures stabilize over the next 24-48 hours. Anatomical closure occurs by one year.
Neutral thermal environment (NTE) is the temperature range in which normal body temperature can
be maintained with minimal metabolic demands and oxygen consumption. One of the ways to
achieve NTE is with a single-walled plastic crib that warms the infant by convection. This is which of
the following?
a. radiant warmer
b. incubator
c. open warmer
d. open crib - CORRECT ANSWER-b. incubator
Persistent bradycardia in a newborn may be the result of all of the following pathologies EXCEPT
a. congenital heart block
b. sepsis
c. congestive heart failure
d. increased intracranial pressure - CORRECT ANSWER-c. congestive heart failure
CHF is a pathology for tachycardia rather than bradycardia. Bradycardia in a newborn is considered a
heart rate of less than 100 beats per minute. Other pathologies include hypoxemia and asphyxia.
Sole creases can help determine gestational age. However, skin dries to a point where sole creases
are no longer a valid indicator of gestational age. This occurs at what time after birth?
a. by 12 hours after birth
b. by 8 hours after birth
c. by 6 hours after birth
d. by 2 hours after birth - CORRECT ANSWER-a. by 12 hours after birth
Which of the following diagnoses is most consistent with a bifid uvula in a newborn?
a. hypothyroidism
b. renal disease
c. cleft lip and palate
d. submucous cleft - CORRECT ANSWER-d. submucous cleft
