A) "I should apply the coal tar in a thin layer and rub it in well."
B) "I can use coal tar on my scalp if my psoriasis is affecting that area."
C) "I should avoid prolonged exposure to sunlight while using coal tar."
D) "The medication can cause systemic effects."

Answer 1

The client needs further teaching if they think coal tar should be rubbed into the skin.

Step-by-step explanation:

The correct answer is A) 'I should apply the coal tar in a thin layer and rub it in well.'

This statement indicates a need for further teaching because coal tar should not be rubbed into the skin. It should be applied in a thin layer without rubbing it in. Rubbing can cause skin irritation and worsen the condition.

Coal tar is commonly prescribed for psoriasis because it helps to slow down the excessive growth of skin cells and reduce inflammation. It can be used on the scalp if needed. However, it is important to note that coal tar can stain the hair and scalp.
