In normal range-of-motion, movement of extremity away from midline of body is termed as

Appeared in: ESIC Nursing Officer-7July 2024

Explanation

Abduction is the anatomical term for moving a limb or body part away from the central midline of the body.
The term 'abduct' means to take away, which is a useful mnemonic for remembering this movement.
As shown in the provided image, lifting the arm laterally away from the torso is a clear example of abduction at the shoulder joint.

Option A: Adduction is the opposite of abduction. It describes the movement of a limb toward the midline of the body.
Option B: Eversion is a specific movement of the foot where the sole turns to face outward, away from the body's midline.
Option C: Inversion is a specific movement of the foot where the sole turns to face inward, toward the body's midline.

Visual 1: Diagram: A side-by-side comparison illustrating abduction (moving away) and adduction (moving toward) for both the arm and the leg.
Visual 2: Diagram: A focused view of the foot showing the difference between inversion (sole inward) and eversion (sole outward).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical Terms of Motion as background academic context rather than a clinical decision trigger.
Nurses must accurately document range of motion using these terms to track patient progress, especially after surgery (e.g., hip or shoulder replacement) or a stroke.
Understanding these terms is vital for correctly implementing physical therapy orders, such as using an abduction pillow to keep a patient's legs separated after hip surgery.
What if? If a patient has a rotator cuff injury, their orders might specify 'limit abduction to 45 degrees'. The nurse must know this means the patient should not lift their arm out to the side more than halfway to shoulder level to prevent further damage.

How to Approach the Question

First, identify the key directional phrase in the question stem, which is 'movement of extremity away from midline'.
Analyze the options. Recognize that 'Eversion' and 'Inversion' are specialized terms for foot movement and are less likely to be the answer for a general 'extremity' question.
Focus on the two most likely options: 'Adduction' and 'Abduction'.
Use a mnemonic: 'Abduct' sounds like being taken away, so it means movement away from the body. 'Adduct' sounds like 'add', so it means adding the limb back to the body.
Based on the mnemonic and definition, select the term that matches 'away from midline'.
