Which type of skin condition would most likely impair a client's sleep quality?

Pruritic skin diseases are characterized by itching, which can significantly disrupt a person's ability to sleep well. The constant urge to scratch can lead to both physical discomfort and aggravation of the skin condition, resulting in a cycle of distress that makes it difficult for individuals to find restful sleep. Itching can cause not only discomfort but also increased anxiety and frustration, further compromising sleep quality.

In contrast, while conditions such as allergic dermatitis, acne, and psoriasis can also cause discomfort and may affect sleep, pruritus is a particularly distressing symptom that is often associated with significant sleep disturbances. The intense itching associated with pruritic skin diseases directly impacts a person's ability to settle down and remain asleep, making it the most likely condition to lead to impaired sleep quality among the options provided.
