Questions and Answers

How does phototherapy benefit newborns with jaundice?

  • It decreases the level of RBCs in the bloodstream.
  • It causes an increase in red blood cell destruction.
  • It promotes bilirubin excretion by inducing lipolysis.
  • It converts bilirubin to a soluble form, aiding in excretion. (correct)

    • In newborns, why does jaundice occur more frequently?

  • As a result of an increased number of platelets in the bloodstream.
  • Due to excessive exposure to sunlight after birth.
  • As a protective mechanism against potential infections.
  • Because of an immature liver unable to excrete excess bilirubin. (correct)

    • What collectively dictates the risk level in newborns when assessing serum bilirubin levels?

  • The baby's response to external stimuli.
  • The matched total serum bilirubin values and hours of life. (correct)
  • The mother's blood type and Rh factor.
  • The presence of red blood cells at specific hours after birth.
