The nurse is performing a vision screening for 4-year-old child. Which of the following screening charts would be best for determining the child's visual acuity?
A) Snellen
B) Ishihara
C) Allen figures
D) Color Vision Testing Made Easy (CVTME)
C
Response:
The Allen figures chart is reliable for assessing the visual acuity of a preschool child. The Snellen chart requires that the child has a good knowledge of the alphabet; this is not a realistic expectation for a 4-year-old child. The Ishihara and Color Vision Testing Made Easy (CVTME) charts are designed to assess color vision discrimination, not visual acuity.
