A Nurse Uses Which Technique to Assess a Patient's Peripheral

A nurse uses which technique to assess a patient's peripheral vision?

A) The nurse asks the patient to keep the head still and by moving the eyes only, follow the nurse's finger as it moves side to side, up and down, and obliquely.
B) The nurse covers one of the patient's eyes with a card and observes the uncovered eye for movement, then removes the card and observes the just uncovered eye for movement.
C) With the patient and nurse facing each other and a card covering their corresponding eyes, the nurse moves an object into the visual field and the patient reports when the object is seen.
D) The nurse shines a light on both corneas at the same time and notes the location of the reflection in each eye.
