Final answer:
The skin infection that should prompt referral to a physician is impetigo, characterized by moist lesions that form crusted sores, while eczema presents as dry. The correct answer is option c).
Step-by-step explanation:
The skin infection characterized by dry or moist lesions that indicates a client should be referred to a physician is impetigo. Impetigo is the skin infection characterized by dry or moist lesions that require a physician's referral. Impetigo presents as vesicles, pustules, or bullae that burst to form crusted sores and is often a result of poor hygiene.
In contrast, eczema is an allergic reaction characterized by dry, itchy patches and flaky rashes that can swell or bleed in severe cases. However, eczema does not necessarily need physician referral unless the symptoms are severe or not responding to over-the-counter treatments.
Impetigo, due to its infectious nature, always requires medical attention to prevent spreading and for appropriate antibiotic treatment.
