Which of the following is a common nursing specialty?

Pediatrics is a common nursing specialty focused on providing care for infants, children, and adolescents. Nurses who specialize in pediatrics are trained to understand the unique medical, emotional, and developmental needs of younger patients. This specialty encompasses a wide range of topics, including growth and development assessment, child health issues, and family dynamics, all of which are critical when caring for pediatric patients. Pediatric nurses often work in hospitals, clinics, or community health settings, emphasizing not only medical care but also family education and support.

The other options listed are not nursing specialties. While human resources management, medical coding, and pharmaceutical sales involve medical and health knowledge, they do not focus on direct patient care in the manner that a nursing specialty does. These roles are important in the healthcare system but fall outside the traditional scope of nursing practice.
