  b. Respiratory distress syndrome
  c. Meconium aspiration syndrome
  d. Persistent pulmonary hypertension

Answer to Question 1

ANS: C
Cryotherapy and laser photocoagulation therapy can be used to minimize the vascular proliferation process that causes the retinal damage. Blindness can be prevented with early recognition and treatment. Cryotherapy and laser therapy can be used to stop the process. Surgical intervention can be used to repair a detached retina if necessary. Long-term administration of oxygen is one of the causes. Oxygen should be used judiciously.

Answer to Question 2

ANS: A
The most common cause of anemia in preterm newborns is frequent blood-sample withdrawal and inadequate erythropoiesis in acutely ill newborns. Microsamples should be used for blood tests, and the amount of blood drawn should be monitored. Respiratory distress syndrome, meconium aspiration syndrome, and persistent pulmonary hypertension are not causes of anemia. They may require frequent blood sampling, which will contribute to the problem of decreased erythropoiesis and anemia.
