What is a recognized long-term risk of cumulative PUVA therapy?
Answer: Increased risk of skin cancer
Long-term cumulative PUVA therapy is associated with an increased risk of squamous cell carcinoma and other UV-induced skin cancers.
Which body area is typically shielded in male patients during full-body phototherapy to reduce cancer risk?
Answer: Genitals
The genitals are shielded during full-body phototherapy to minimize cumulative UV exposure to this area, which is most susceptible to UV-induced carcinogenesis.
What is the role of the dermatology tech during a phototherapy session?
Answer: Set up equipment and monitor patient per physician protocol
The dermatology tech sets up phototherapy equipment, verifies dose settings per physician orders, and monitors patient comfort and safety throughout the session.
Which symptom indicates a phototherapy overdose reaction requiring immediate intervention?
Answer: Severe blistering and pain
Severe blistering and pain indicate a phototherapy overdose and require immediate discontinuation and physician notification.
Which condition is a contraindication for phototherapy due to UV-triggered flares?
Answer: Lupus erythematosus
Lupus erythematosus is a contraindication for phototherapy because UV exposure can trigger or worsen lupus disease activity and systemic flares.
What information must be documented in a phototherapy patient treatment log?
Answer: Treatment dates, UV doses delivered, skin response, and MED
A complete phototherapy log documenting dates, delivered UV doses, skin response, and MED is required for safety monitoring, dose titration, and medicolegal documentation.
