The nurse is educating a student on the proper use of an ophthalmoscope for an eye examination. Which statement by the nurse to the student is accurate?
1. "I'm going to examine the client's right eye with my left eye."
2. "I'm going to advance the ophthalmoscope until the instrument touches the client's cornea."
3. "I'm going to begin with the lens set to the 0 diopter."
4. "I can see the red reflex as the light reflects off of the client's lens."
Correct Answer: 3
The nurse should always begin with the lens set to the 0 diopter. The nurse should prepare to assess the client's eye with an ophthalmoscope by examining the client's right eye with the nurse's right eye. The nurse should advance the ophthalmoscope only until it almost touches the client's eyelashes. The cornea contains many nerve endings and this would be painful for the client. The red reflex is seen as light reflects off of the client's retina, not his lens.
