Questions and Answers

In the context of Tetralogy of Fallot, what compensatory mechanism primarily contributes to the occurrence of 'Tet spells'?

  • Progressive dilation of the aorta overriding the ventricular septum, reducing systemic blood return
  • Spasms of the infundibular septum, causing increased obstruction of the right ventricular outflow tract (correct)
  • Increased systemic vascular resistance due to polycythemia
  • Sudden decrease in pulmonary vascular resistance leading to increased pulmonary blood flow

Why is it critical to avoid palpating the abdomen in a child diagnosed with Wilms tumor?

  • To minimize the spread of the tumor to adjacent organs
  • To prevent exacerbation of pain and discomfort
  • To prevent potential rupture of the tumor capsule and subsequent seeding (correct)
  • To avoid stimulating catecholamine release causing hypertensive crisis

What is the primary rationale for initiating strict infection control measures in pediatric patients undergoing chemotherapy?

  • Chemotherapy compromises the patient's immune system, increasing vulnerability to opportunistic infection. (correct)
  • Chemotherapy drugs are directly toxic to common environmental pathogens.
  • Chemotherapy increases the risk of transmitting infections to hospital staff.
  • Chemotherapy disrupts the normal flora, creating an environment conducive to fungal overgrowth.
