  2. 32-week-gestation infant who needed no oxygen and weighed 1850 grams.
  3. 28-week-gestation infant who has been on long-term oxygen and weighed 1400 grams.

Answer to Question 1

Correct Answer: 3
Rationale: The 28-week-gestation infant on oxygen weighing 1400 grams has the highest risk of retinopathy of prematurity because of gestational age (28 weeks or less), weight (less than 1500 g), and oxygen therapy. The other neonates have fewer risk factors.

Answer to Question 2

Correct Answer: 1
Rationale: The cover/uncover test can detect abnormal musculature of the eye that can lead to asymmetric eye movement. An ophthalmologic eye exam allows the practitioner to view the internal structures of the eye, not abnormal musculature. A vision acuity test is used to test for myopia. A pupil-reaction-to-light test evaluates neurological status.
