Phenylephrine (Neo-Synephrine) is administered to a client before a diagnostic procedure. The client education about this medication should include:
1. Driving may be difficult.
2. Tears will be yellow.
3. May cause burning.
4. Sunlight will improve vision.
Driving may be difficult.
Rationale: Phenylephrine causes pupillary dilation. The nurse should inform the client that driving with eyes dilated may cause difficulty, especially on a sunny day. Patients should be instructed to wear sunglasses to block ultraviolet (UV) exposure. The pupils are unable to react to or decrease the amount of light entering the eye. Burning is an adverse reaction to phenylephrine. Medications that numb the eye, such as Proparacaine, will cause the tears to be yellow.
