Which action best describes maintaining a side-lying position with proper knee alignment?

• A. Leave resident positioned on side with upper knee bent in front of the lower leg
• B. Leave resident positioned on side with back leg tucked under the front leg
• C. Leave resident positioned on side with upper knee straight
• D. Place device/padding between legs so that bony prominences of the knees and ankles are separated

Answer: (D)

In side-lying, keeping the legs in proper alignment is essential to prevent pressure and friction on the knee and ankle joints and to maintain a straight spine and hips. Placing a padding or device between the legs separates the knees and ankles so they don’t press against each other, which helps distribute weight more evenly and reduces the risk of skin breakdown or joint strain.

The other positions either twist or compress the legs—bending the upper knee in front of the lower leg can misalign the hip and put uneven pressure on one knee; tucking the back leg under the front leg can force an awkward, unstable position; and leaving the upper knee straight can allow the knees to rest against each other or the bed, increasing pressure.
