Question 4 of 5
The nurse is caring for a client diagnosed with psoriasis vulgaris who is receiving a psoralen and ultraviolet light (PUVA) treatment. Which assessment finding indicates that the client has been exposed to the treatment?
Correct Answer: A
Rationale: Tenderness upon palpation and generalized erythema indicate exposure to PUVA treatment for psoriasis vulgaris. PUVA combines psoralen (photosensitizing agent) with UVA light, causing skin inflammation and redness as a therapeutic effect to reduce plaques. Thick plaques are the disease itself, not a treatment sign, photosensitivity may occur but isn't specific, and wart-like papules are unrelated. Erythema and tenderness are expected post-PUVA, reflecting its mechanism of action on skin cell turnover.
Question 5 of 5
The nurse assesses an adult client 24 hours after a bowel exploration and formation of a sigmoid colostomy. Which assessment finding should be reported to the surgeon immediately?
Correct Answer: C
Rationale: A purple stoma mucosa 24 hours post-sigmoid colostomy should be reported to the surgeon immediately. This color indicates potential ischemia or necrosis due to inadequate blood supply, a surgical emergency risking stoma failure or perforation. Bright red blood is normal initially, absent bowel sounds are expected post-op, and solid brown fecal matter is typical, but purple mucosa signals compromised tissue viability, necessitating urgent evaluation and possible revision.
