characteristics of congenital heart disease, the instructor
determines that the teaching has been successful when
the class identifies which defect as an example of a
disorder involving increased pulmonary blood flow?
A. Tetralogy of Fallot
B. Atrial septal defect
C. Hypoplastic left heart syndrome
D. Transposition of the great vessels - Answer-B

A child with heart failure is receiving supplemental oxygen.
The nurse understands that in addition to improving
oxygen saturation, this intervention also has what effect?
A. Cause vasodilation
B. Increase pulmonary vascular resistance
C. Promote diuresis
D. Mobilize secretions - Answer-A
Rationale: Oxygen improves oxygen saturation and also
functions as a vasodilator and decreases pulmonary
vascular resistance. Diuretics promote dieresis. Chest
physiotherapy helps to mobilize secretions.
During a follow-up visit, the parents of a 5-month-old infant
diagnosed with congenital heart disease tell the nurse,
"We're just so tired and emotionally spent. All these tests

A. Risk for delayed growth and development related to
necessary treatments
B. Deficient knowledge related to the care of a child with
congenital heart disease
C. Interrupted family processes related to demands of
caring for the ill child
D. Fear related to infant's cardiac condition and need for
ongoing care - Answer-C
Rationale: The statements by the parents indicate that
there is disruption in the family resulting from the demands
of caring for the ill infant and they verbalized concern
about their older child. The child may be at risk for delayed
growth and development, but this is not indicated by the
parents' statements. The parents may lack knowledge
about their infant's condition and they may be
experiencing fear about the infant's condition, but the
statements reflect issues related to the family functioning.
A nurse is caring for a newborn with congenital heart
disease (CHD). Which finding would the nurse interpret as
indicating distress?
A. Reduced respiratory rate during feeding
, 4|Page
B. Subcostal retraction at the time of feeding
C. Perspiration on body after feeding
D. Feeding lasting for 15-20 minutes - Answer-B
Rationale: Subcostal retraction during feeding is indicative
of distress associated with feeding in newborn infants with
CHD. Feeding can be a stress to newborns with CHD who
are seriously compromised. Additional features indicating
distress in infants with CHD include increased respiratory
rate, perspiration along the hairline during feeding and
feeding time longer than 30 minutes.
The nurse is caring for an infant with suspected patent
ductus arteriosus. Which assessment finding would the
nurse identify as helping to confirm this suspicion?

clavicle
C. Faint pulses
D. Systolic murmur best heard along the left sternal border
