A patient is undergoing psoralen plus ultraviolet A light (PUVA) therapy for treatment of psoriasis. What action should the nurse take to prevent adverse effects from this procedure?
a. Cleanse the skin carefully with an antiseptic soap.
b. Shield any unaffected areas with lead-lined drapes.
c. Have the patient use protective eyewear while receiving PUVA.
d. Apply petroleum jelly to the areas surrounding the psoriatic lesions.
ANS: C
The eyes should be shielded from UV light (UVL) during and after PUVA therapy to prevent the development of cataracts. The patient should be taught about the effects of UVL on unaffected skin, but lead-lined drapes, use of antiseptic soap, and petroleum jelly are not used to prevent skin damage.
