NCLEX PN Practice Test Practice Question
A person who has psoriasis is seen in the clinic. The lesions are covered with coal tar. Which instruction should the nurse give the client?
Correct Answer: B
Rationale: Option B is appropriate as coal tar can increase sensitivity to sunlight, making the skin more susceptible to burns. Therefore, protecting the area from sunlight for 24 hours is crucial.
Option A is misleading; while nausea and vomiting are concerning, they are not common side effects of coal tar treatment and do not directly relate to the application instructions.
Option C is incorrect because coal tar is typically left on the skin for longer periods to be effective, often overnight, rather than being washed off after six to eight hours.
Option D is not relevant since darkening of the skin can occur but is usually not a reason for concern during treatment, unless accompanied by other symptoms.
