The nurse's assessment of a patient with significant visual losses reveals that the patient cannot count fingers. How should the nurse proceed with assessment of the patient's visual acuity?
A) Assess the patient's vision using a Snellen chart.
B) Determine whether the patient is able to see the nurse's hand motion.
C) Perform a detailed examination of the patient's external eye structures.
D) Palpate the patient's periocular regions.
Ans: B
Feedback:
If the patient cannot count fingers, the examiner raises one hand up and down or moves it side to side and asks in which direction the hand is moving. An inability to count fingers precludes the use of a Snellen chart. Palpation and examination cannot ascertain visual acuity.
