Harvey is a nursing assistant. He works at a hospital providing basic care to patients, such as helping them at meal times, walk
ing, or bathing. He also monitors patients’ conditions by taking their vital signs. Harvey works in A.Biotechnology Research and Development.
B.Diagnostic Services.
C.Health Informatics.
D.Therapeutic Services.
It is clear that Harvey does not any diagnostic work, he just helps with treatment, so B is wrong. Health informatics is the branch where computer science applications are used for health purposes; from the description this is also excluded. Similarly, his job does not involve biotechnology research, even if his patients use some biotechnology themselves. The most apt description of his work is D, therapeutic services. He helps patients get over their disease and he takes care of the most basic measurements of his patients.
