Positioning involves placing a patient in various body alignments to promote health, comfort, and the ability to perform medical procedures. The goals of positioning are to relieve pressure, improve circulation, prevent deformities, and allow for assessments and interventions. Factors such as a patient's needs, abilities, disease, and consciousness level must be considered when determining the appropriate position. Common positions include supine, lateral, prone, and Fowler's position, each used for different medical purposes and procedures. Careful positioning is important for patient comfort and skin integrity.
