When caring for a 3 year old with tetralogy of Fallot, he nurse expects to see fatigue and poor activity tolerance. This is caused by:

  • A. Poor muscle tone
  • B. Inadequate oxygenation of tissues.
  • C. Restricted blood flow leaving the heart
  • D. Inadequate intake of food.
Correct Answer: B

Rationale: Tetralogy of Fallot is a heart defect that involves four specific abnormalities in the heart's structure. One of these abnormalities is a ventricular septal defect, which results in a mixing of oxygenated and deoxygenated blood. This leads to inadequate oxygenation of tissues because some of the blood that is pumped out to the body is not fully oxygenated. As a result, the child may experience fatigue and poor activity tolerance due to the reduced oxygen supply to the tissues and organs. This is why the nurse would expect to see these symptoms in a 3-year-old with tetralogy of Fallot.
