Body Mechanics: it is important to the nurse to observe the correct body mechanics in order to prevent quick tiring, back problems and muscle pain.
❖Anatomy and Physiology: the conscious knowledge of the normal state and condition of certain parts of the body wherein one would be able to tell any abnormality. The body exerts uneven points of pressure against different areas of the mattress. The sacrum may become the site for pre-assure sore because of the weight of the patient's body and a reduced blood supply over bony prominence.
❖Chemistry: woolen blanket fibers may cause irritation to the patient's skin; there must be always be a sheet to separate the blanket from the patient. Strong detergent, soaps and bleaches used in commercial laundries may cause skin irritation if bed linens are not thoroughly rinsed.
❖Microbiology: pathogenic materials may be transferred from the source to a new host directly by contaminated linen. Hands should be washed before and after making the bed. Bed linen should be folded away from the body to minimize transfer microorganisms to the clothing. Fanning bed clothes stirs up bacteria in the air, and air motion is a method of transfer.
❖Physics: friction can irritate the skin and causes rashes. It is appropriate to keep the lines smooth and wrinkle-free.
❖Psychology: use skill and efficiency in making the bed to minimize undue exertion and fatigue for the patient. If the procedure brings comfort and relaxation, the patient's attitude will improve.
