A patient who is using atropine eyedrops is found to have a poor consensual light response. The nurse recognizes that this finding is considered:
1. abnormal and should be reported to the physician.
2. normal because of the eyedrops.
3. evidence of retinal degeneration.
4. evidence of optic nerve damage.
Correct Answer: 2
Some eye medications may cause unequal dilation, constriction, or inequality of pupil size. Morphine and narcotic drugs may cause small, unresponsive pupils, and anticholinergic drugs such as atropine may cause dilated, unresponsive pupils. This is a normal response and does not need to be reported to the physician. Retinal degeneration is evidenced by an inability of the pupils to respond appropriately to light. Damage to the optic nerve would likely produce visual disturbances.
