NSPN 7100 (Obstetrics Medicine) FINAL
EXAM QUESTIONS AND CORRECT
ANSWERS.
When ventilation and perfusion is mismatched impaired gas exchange
occurs.
True or false?
True.
Fetal hemoglobin has a higher affinity for binding with 02 than adult
hemoglobin.
True or false?
True.
A right shift in the oxyhemoglobin dissociation curve means that the
affinity of hemoglobin for oxygen is reduced. This is commonly due to low
temperature, alkalosis, and low PaC02.
True or false?
False.
The main determinants of oxygen supply are:
a) The amount of oxygen in arterial blood when it leaves the lungs, the
capacity of the blood to transport 02 to the cells, the effectiveness of the
pump that circulates the blood throughout the body
b) Adequate cardiac output, normal blood pressure, Fi02
c) The capacity of the blood to transport 02, the amount of oxygen the cells
require, temperature level, activity, and stress
d) All of the above
,A. The amount of oxygen in arterial blood when it leaves the lungs, the
capacity of the blood to transport 02 to the cells, the effectiveness of the
pump that circulates the blood throughout the body.
The term IUGR should be used when there is evidence of abnormal genetic
or environmental influences affecting growth.
True or false?
True
Secondary apnea is NOT responsive to stimulation in the delivery room. It
requires IPPV.
True or false?
True
Oral immune therapy can only be used in infants with an intact
suck/swallow reflex?
True or false?
False
It is not possible for an adolescent mother to have a healthy pregnancy,
birth, and postpartum period.
True or false?
False
Oral immune therapy:
a) Is not evidence-based
b) Is a powerful antimicrobial agent and by coating the infant's mouth
with milk, a front-line defense is provided
c) Is a rich source of cytokines, and these cytokines may be absorbed
through the infant's buccal mucosa, thus positively impacting the infant's
, immune system
d) Is only appropriate in infants over 32 weeks
e) B and C
E: B and C.
Necrotizing enterocolitis affects only preterm infants.
True or false?
False
Early and adequate nutritional support of preterm infants:
a) Improves neurodevelopmental outcomes
b) Is not possible to achieve in the NICU environment
c) Is only possible with the addition of formula
d) Should be delayed as early enteral feeding is associated with increased
risk for NEC
A. Improves neurodevelopmental outcomes
Infants of teen mothers are at a greater risk of being born low birth weight,
premature, and with other poor pregnancy outcomes.
True or false?
True.
Neonates have a unique response to hypoxemia and C02 retention. Adults
will have a sustained increase in ventilation, but infants will have a brief
period of increased ventilation followed by respiratory depression?
True or false?
True
Probiotic use is NOT appropriate for use in preterm infants.
True or false?
