Unit 2 Role Profile
[Instructor Name]
[Date]
Figures from labor data are bracketed because they are revised each year; the author's reading date is stated in the profile.
Why This Profession
I chose to profile diagnostic medical sonography because sonographers and nurses work side by side in emergency departments, labor and delivery units and outpatient clinics, yet I knew little about how sonographers are trained or what they are allowed to do. The profile below draws on the federal government's occupational data, the accrediting body for educational programs and the main credentialing organization, all read on [date].
What Sonographers Do
Diagnostic medical sonographers use equipment that sends high-frequency sound waves into the body and records the echoes to create images of organs, blood vessels and developing fetuses. They prepare and position patients, select the right transducer and settings, capture images, judge whether the images are good enough for a diagnosis, and write a summary of their findings for the physician who interprets the study. Many specialize, for example in abdominal, obstetric and gynecologic, breast, vascular or cardiac imaging (U.S. Bureau of Labor Statistics, 2024). They do not make the final diagnosis; a radiologist, cardiologist or other physician does.
Education and Accreditation
Most sonographers complete an associate or bachelor's degree, or a certificate program for people who already hold a degree in another health field. Programs combine classroom study of anatomy, physics and instrumentation with supervised clinical scanning. Programs can be accredited by the Commission on Accreditation of Allied Health Education Programs, which reviews curricula and clinical training against published standards (Commission on Accreditation of Allied Health Education Programs, n.d.). Graduating from an accredited program matters because it opens the most direct route to certification.
Credential and Certification
The main credentialing body is the American Registry for Diagnostic Medical Sonography. Its Registered Diagnostic Medical Sonographer credential requires passing an examination on sonography principles and instrumentation and at least one specialty examination, such as abdomen or obstetrics and gynecology. Credential holders must complete continuing medical education to keep the credential active (American Registry for Diagnostic Medical Sonography, n.d.).
Unlike nursing, sonography is not licensed in most states; the credential, not a state license, is usually what an employer checks.
Only a few states require a license to practice sonography. In most, employers require a credential from a recognized body as a condition of hiring, and many insurers and accrediting bodies for imaging departments expect credentialed staff (U.S. Bureau of Labor Statistics, 2024). This is a real difference from nursing, where a state board license is required everywhere.
Settings and Working Conditions
Most sonographers work in hospitals, with others in physician offices, medical and diagnostic laboratories, and outpatient care centers. The work involves long periods of standing, reaching and pressing a transducer against patients, and work-related musculoskeletal injury, particularly of the shoulder and wrist, is a recognized occupational risk. Hospital-based sonographers may work evenings, weekends and on-call shifts for emergencies.
Employment Outlook
Federal labor data projected employment of diagnostic medical sonographers to grow [faster than average] over the coming decade, with a median annual wage of about $[84,000] in the most recent year reported (U.S. Bureau of Labor Statistics, 2024). Demand is linked to an aging population and to the use of ultrasound as an imaging method that does not use ionizing radiation. These figures are revised each year, so they are bracketed here and should be checked against the current edition.
Where Sonographers and Nurses Meet
Nurses often prepare patients for ultrasound, for example by explaining a full-bladder requirement for a pelvic study or ensuring a patient has not eaten before a gallbladder scan. In labor and delivery, nurses and sonographers both care for the same patient during urgent scans. Sonographers may notice a finding that needs immediate attention, such as signs of a ruptured ectopic pregnancy, and must communicate it quickly through the department's process; nurses at the bedside are often the next to act. Understanding each other's preparation steps and limits prevents delays, such as a patient who arrives for a scan without the required preparation.
Questions I Would Still Ask
Written sources answered most of my questions but not all. I would still want to ask a working sonographer how much of the day is spent scanning compared with documenting and waiting for patients, how departments decide when a sonographer should call a physician about an urgent finding rather than simply sending images, and what they do to protect their shoulders over a long career. I would also ask how they talk with a pregnant patient who senses from the room's silence that something is wrong, since sonographers are not the ones who deliver a diagnosis. These questions point to parts of the role that labor data and credential rules cannot show.
What I Learned
Before this profile, I assumed sonographers were licensed the way nurses are. Learning that the credential carries most of the weight changed how I understand quality in imaging, and it showed me the value of checking a profession's own organizations rather than relying on impressions.

Reading the NU 108 Unit 2 instructions
Unit 2 usually asks for a profile of one health profession built from credible sources. Prompts commonly want the education and credential required, the body that regulates or certifies practice, typical settings and duties, the employment outlook, and how the profession works with others, often three to four pages with at least three sources. Instructors look for each factual claim tied to a named, authoritative source such as a federal labor agency, an accrediting body or a credentialing organization, rather than general websites. Figures such as wages and growth rates should be dated, since they are revised regularly. Comparing the profession with your own and noting what you could not learn from documents show deeper engagement.
How this NU108 Unit 2 example is built
The profile opens with why the author chose sonography and which sources were read, with the date. Duties and specialties come from federal labor data, with the point that physicians make the final diagnosis. Education and accreditation follow, then the credential, its examinations and continuing education. The highlighted line marks that most states do not license sonographers, a contrast with nursing. Settings and working conditions include shoulder and wrist injury as a known risk. The outlook section brackets wage and growth figures because they change yearly. Sections on where sonographers and nurses meet and on questions still to ask lead to a short statement of what the author learned. Every claim in the body can be traced to one of the three sources listed at the end.
NU108 Unit 2 rubric: what earns full points
Role profiles in NU 108 are generally graded on accuracy, use of credible sources, completeness, and insight. Accuracy earns credit when education, credentialing and scope are described correctly for the profession. Source points go to profiles that attach each claim to a named, authoritative source cited in APA 7 and dated where figures change. Completeness rewards covering every element the prompt lists, including outlook and interprofessional connections. Insight is judged on comparisons with nursing and on recognizing what documents cannot reveal about daily work. Organization under clear headings and professional writing make up the rest of most rubrics, with deductions for unsupported claims. Where a profession is regulated differently from state to state, saying so accurately is itself a sign of careful research.
Common NU108 Unit 2 mistakes, and how to avoid them
Role profiles often lose points by relying on school marketing pages or general career sites instead of the profession's own credentialing and accrediting bodies. Another common error is assuming the profession is licensed the way nursing is, without checking. Some profiles copy wage figures without a date, which may be out of date by the time the paper is read. Many describe duties but never explain how the profession works with nurses. Use the federal labor agency, the accreditor and the credentialing body, date every figure, check how the profession is regulated in your state, and include at least one point of contact with nursing practice. Finally, list what you still do not know.

You can read the complete NU108 Unit 2 role profile of the diagnostic medical sonographer here, covering duties, education, the credential, settings, outlook, links with nursing and open questions, with three references. We can profile a different profession for you on request.
Are sonographers licensed like nurses?
In most states, no. A few states require a license, but in most the credential from a recognized certifying body is what employers require. Nursing, by contrast, requires a state board license everywhere.
What sources should an NU108 role profile use?
Authoritative ones: the federal Occupational Outlook Handbook for duties and outlook, the profession's accrediting body for education, and its credentialing organization for certification, each cited and dated.
Why are wage figures bracketed in the sample?
Federal labor data are revised every year. Bracketing the figure and stating the reading date reminds the reader to check the current edition before relying on the number.
How do sonographers and nurses work together?
Nurses often prepare patients for scans, such as fasting or a full bladder, and act on urgent findings that sonographers report. Knowing each other's preparation steps and limits prevents delays and repeated scans.
