Answer to Question 1

ANS: D
Pplateau is measured during mechanical ventilation and represents the amount of pressure needed to maintain the tidal volume within the patient's lungs during a period of no gas flow.

Answer to Question 2

ANS: B
FEV1 and peak expiratory flows are routine measurements during spirometry. Maximum inspira-tory pressure is a common airway pressure measurement made on spontaneously breathing pa-tients. Raw is calculated by subtracting plateau pressure (Pplateau) from peak inspiratory pressure and dividing the resultant pressure by the airflow.

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.
