Which condition is listed as a contraindication to UV light therapy?

• A. Tuberculosis
• B. Asthma
• C. Hypertension
• D. Recent Sun Exposure

Answer: (A)

UV light therapy is used to treat certain skin conditions by delivering controlled UV radiation, but not everyone is a candidate. The main safety concerns are active infections, photosensitivity, and overall health status. An active tuberculosis infection is a listed contraindication because it represents an infectious disease that raises infection-control concerns and suggests the patient may not tolerate additional procedures or exposures right now. Treating such a patient with UV light in a shared clinical space could pose risks to others and to the patient, so it’s avoided.

Asthma and hypertension don't inherently worsen with UV exposure, so they aren’t considered absolute contraindications. Recent sun exposure is a caution because the skin could already be photosensitive or sunburned, increasing risk, but it’s not treated the same way as an active infection.
