Final answer:
The skin infection with dry or moist lesions that warrants a physician's referral is impetigo, characterized by vesicles, pustules, or bullae that rupture and form encrusted sores.
Step-by-step explanation:
The skin infection that is characterized by dry or moist lesions and indicates that clients should be referred to a physician is impetigo. Impetigo is a contagious infection usually caused by Staphylococcus aureus or Streptococcus pyogenes. It features the formation of vesicles, pustules, or bullae that rupture, leading to encrusted sores often around the nose and mouth. The condition can manifest in nonbullous or bullous forms, with bullae being large, fluid-filled blisters. When they rupture, they result in larger draining lesions with a typical yellowish crust. It is crucial for individuals with impetigo to seek medical treatment, as it requires antibiotic therapy to prevent spread and complications.
