The nurse has admitted a child with tricuspid atresia. The nurse would expect which initial lab result?
A high hemoglobin
A prolonged PTT
A low hematocrit
A low platelet count
The Correct Answer is A
a) A high hemoglobin: Tricuspid atresia typically leads to decreased pulmonary blood flow, causing cyanosis and chronic hypoxemia, which can result in increased hemoglobin levels as the body compensates for low oxygen.
b) A prolonged PTT: While not typically associated with tricuspid atresia specifically.
c) A low hematocrit: Hematocrit levels might be normal or elevated due to chronic hypoxemia.
d) A low platelet count: Platelet count might not be directly affected by tricuspid atresia.
