ANS: D
Visual acuity is measured as a fraction, in which the top number is the distance that the patient is
standing from the chart; the bottom number is the distance that an average person can stand and still
read the line.
DIF: Cognitive Level: Analyzing (Analysis)
OBJ: Nursing process assessment MSC: Physiologic Integrity: Physiologic Adaptation
5. The cri erion for de ermining he adeq ac of a pa ien s is al field is:
