Which of the following is a primary responsibility of nail technicians regarding client health?

Identifying and referring infections is a primary responsibility of nail technicians regarding client health because it involves recognizing potential issues that could be harmful to the client or others. Nail technicians are trained to observe and identify signs of nail and skin conditions, such as fungal infections, bacterial infections, or other anomalies that could affect the client's health.

When a technician suspects an infection, they should refer the client to a medical professional for further evaluation and treatment. This referral process is crucial in ensuring the client receives appropriate care and helps prevent the spread of infections. By staying vigilant and knowledgeable about these health concerns, nail technicians play a significant role in maintaining the safety and health of their clientele.

The other options involve responsibilities that are outside the scope of practice for a nail technician. Performing surgeries and administering medication require medical training and are typically reserved for licensed healthcare professionals. Providing nutritional advice, while beneficial in a holistic health context, is generally not within the purview of a nail technician's training and focus on nail care and hygiene.
