NEONATAL HEMATOLOGY EXAM 2025|158 QUESTIONS
WITH ACCURATE SOLUTIONS
1. In a clinical scenario, if a neonate presents with thrombocytopenia and
hyperbilirubinemia, what could be a potential underlying cause related to
erythrocyte defects?
Hemolytic anemia due to erythrocyte structural defects
Vitamin K deficiency leading to bleeding disorders
Infection causing sepsis
Dehydration resulting in concentrated blood
2. If a preterm infant's bilirubin levels remain elevated beyond 30 days, what
clinical condition should be investigated further?
Kernicterus
Hemophilia
Thrombocytopenia
Vitamin K deficiency
3. Decisions about undertaking exchange transfusion are based primarily
on the
bilirubin level and the rate of bilirubin accumulation.
level of anti-D and the rate of bilirubin accumulation.
bilirubin level and the development of generalized edema.
level of anti-D and the development of generalized edema.
4. Which of the following is associated with the development of conjugated
hyperbilirubinemia
Excessive production of bilirubin
, Reduced hepatocyte uptake
Impaired conjugation of bilirubin
Impaired bile flow
5. What lab test is considered the gold standard for monitoring low
molecular weight heparins such as enoxaparin?
Fibrinogen
Anti-factor Xa
Activated partial thromboplastin time
International normalized ratio
Adenosine
6. What is the Vitamin K content of human breast milk compared to bovine-
based formula?
More than bovine formula
Less than bovine formula
The same as bovine formula
Not specified in the text
7. One gram of heme produces how much bilirubin?
18 mg
26 mg
34 mg
8. Describe the anatomical position of the liver in a newborn infant and its
clinical significance.
The liver is located in the right upper quadrant, which is
important for assessing liver size and function during
, examinations.
The liver is located in the left upper quadrant, indicating potential
abnormalities.
The liver is located in the lower abdomen, which is typical for
newborns.
The liver is located midline, which is common in infants.
9. If a newborn is diagnosed with kernicterus, which type of cerebral palsy
might they be at risk for developing, and what implications does this have
for their long-term care?
Dyskinetic cerebral palsy, which may require specialized
therapies and interventions.
Spastic diplegic cerebral palsy, which has no impact on mobility.
Ataxic cerebral palsy, which does not require any long-term care.
No cerebral palsy, as kernicterus does not lead to motor
impairments.
10. A child who received multiple blood transfusions after correction of a
congenital heart defect is demonstrating muscular irritability and is
oozing blood from the surgical incision. Which serum value is most
important for the nurse before reporting to the healthcare provider?
CO combining power
Calcium
Sodium
Chloride
11. Describe the significance of elevated fibrin degradation products in the
context of DIC.
Elevated fibrin degradation products indicate increased
fibrinolysis and are a marker of DIC.
, Elevated fibrin degradation products suggest normal coagulation
function.
Elevated fibrin degradation products are unrelated to coagulation
disorders.
Elevated fibrin degradation products indicate a deficiency in
vitamin K.
12. Describe how kernicterus can lead to different types of cerebral palsy in
affected infants.
Kernicterus can damage brain areas responsible for motor
control, leading to various forms of cerebral palsy such as
spastic diplegic or dyskinetic types.
Kernicterus primarily affects the respiratory system, causing
breathing difficulties.
Kernicterus leads to an increase in bilirubin levels without
neurological consequences.
Kernicterus is solely responsible for causing hemophilia in
newborns.
13. If a researcher observes the absence of erythroid and macrophage
progenitor cells by day 19 in an embryo, what potential implications
could this have for the embryo's development?
It could lead to anemia and increased susceptibility to
infections due to impaired blood cell production.
It would have no significant impact on development.
It might enhance the embryo's immune response.
It could result in accelerated neural development.
14. What is the primary cause of conjugated hyperbilirubinemia?
Conjugation of the bilirubin molecule
