Answer to Question 1

ANS: A
The origin of retinopathy of prematurity, especially with regard to the role of oxygen, is contro-versial. Nonetheless, care should be taken when supplemental oxygen is provided to preterm in-fants (<37 weeks' gestation). it is suggested that oxygen supplementation should not result in a pao2>80 mm Hg.

Answer to Question 2

ANS: A
3 L/min  4 = 12 L/min + 20 = 32 FIO2. The flow is multiplied by 4 because for every 1 L/min of oxygen flowing to a nasal cannula the FIO2 increases by 4. The 20 is the number that the flow multiplied by 4 is added to, in order to get the approximate FIO2.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
