What is moving the hand towards the midline of the body called?

Appeared in: MP CHO -2019 (Shift-1)

Explanation

Adduction is the anatomical term for the movement of a limb or other part toward the midline of the body.
The question describes moving the hand towards the midline, which directly corresponds to the definition of adduction.
A helpful mnemonic is to think of 'adding' the limb to the body.

Option A: Abduction is the opposite of adduction. It describes moving a limb away from the midline of the body.
Option B: Flexion involves decreasing the angle of a joint, such as bending the elbow or knee.
Option D: Extension involves increasing the angle of a joint, essentially straightening it.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical Terms of Movement as background academic context rather than a clinical decision trigger.
Nurses must accurately document patient mobility and any limitations. Using precise terms like 'adduction' and 'abduction' ensures clear and professional communication in patient charts.
These terms are essential when performing passive or active Range of Motion (ROM) exercises to maintain joint function and prevent complications like contractures in immobilized patients.
What if? If a patient has had a stroke affecting their right side and has limited active adduction of the right arm, the nurse would need to perform passive adduction exercises to maintain joint health and prevent 'frozen shoulder'.

How to Approach the Question

First, identify the key action described in the question: 'moving the hand towards the midline'.
Break down the term 'midline'. This is the imaginary vertical line that divides the body into equal right and left halves.
Analyze the directional word: 'towards'. The movement is directed inward, closer to the center of the body.
Recall the definitions of the options. 'Adduction' means to move towards the midline, and 'Abduction' means to move away.
Use a mnemonic: 'Adduction' is like 'adding' a limb to the body. 'Abduction' is like being 'abducted' or taken away.
Based on the definition and mnemonic, select the term that matches the action of moving 'towards the midline'.
