rotation

 [ro-ta´shun]
1. the process of turning around an axis.
2. in obstetrics, the turning of the fetal head (or presenting part) for proper orientation to the pelvic axis. It should occur naturally, but if it does not it must be accomplished manually or instrumentally by the obstetrician or manually by the nurse-midwife.
3. a clinical assignment for students in a specific clinical area.
4. in dentistry, the turning of a malturned tooth into its proper position.
pelvic rotation movement of the pelvis around an imaginary axis.
site rotation the selection of sequential injection locations for a patient receiving multiple injections. A chart is frequently utilized to guide the nurse in rotating sites so that the same location is not used repeatedly, which would lead to tissue damage and irregular absorption of drugs.

ro·ta·tion

(rō-tā'shŭn),
1. Turning or movement of a body around its axis.
2. A recurrence in regular order of certain events, such as the symptoms of a periodic disease.
3. In medical education, a period of time on a particular service or specialty.
[L. rotatio, fr. roto, pp. rotatus, to revolve, rotate]

rotation

Movement around an axis Graduate education A period of time during which a medical student, or a physician in an early period of his training works in a particular service. See Audition rotation, Clinical rotation, Extern, Intern Obstetrics The turning of a fetus around its long axis such that the presenting part changes. See External rotation, Internal rotation, Limb rotation.
