Explanation

The primary goal of body mechanics is to perform work safely and efficiently, which minimizes physical stress (strain) and conserves energy (reducing fatigue).
This directly reduces the risk of musculoskeletal injuries (MSIs), such as back injuries, which are a major occupational hazard in nursing.
Using proper techniques ensures that movements are coordinated and balanced, placing the least amount of stress on the body's structures.
Conserving energy allows the nurse to maintain performance and alertness throughout their shift.

Option A: Maintaining good posture is a fundamental principle or component of body mechanics, but it is the means to an end, not the ultimate objective itself.
Option B: While beneficial, muscle strength alone is insufficient to prevent injury. Proper technique is more critical. The objective is to use the body correctly, regardless of individual strength.
Option D: This is a cognitive outcome, not a direct physical objective of body mechanics. While physical fatigue can lead to cognitive errors, the immediate goal of body mechanics is physical safety and efficiency.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Objective of Body Mechanics in Nursing as background academic context rather than a clinical decision trigger.
Nurses have one of the highest rates of work-related musculoskeletal injuries (MSIs), particularly back injuries. Applying proper body mechanics is a critical competency to ensure both nurse and patient safety.
Correct body mechanics is not just about lifting; it applies to all movements, including pushing, pulling, and repositioning patients, which are frequent nursing tasks.
What if the patient is bariatric and unable to assist with a transfer? The principles of body mechanics (e.g., keeping the center of gravity close) still apply, but they must be supplemented with appropriate bariatric assistive devices (e.g., a ceiling lift, air-assisted transfer device) and adequate help from other staff. Manual lifting in such situations is unsafe and should be avoided.

How to Approach the Question

First, identify the core concept of the question: the 'objective' or 'main purpose' of body mechanics for a nurse.
Analyze the options to differentiate between the ultimate goal, the methods to achieve that goal, and any prerequisites or indirect benefits.
Recognize that 'maintaining posture' and 'having good muscle strength' are methods or contributing factors, not the end goal.
Identify that 'making fewer mistakes' is an indirect, secondary benefit of being less fatigued, not the primary physical objective.
Conclude that 'avoiding strain and fatigue' best describes the primary purpose of using the body efficiently and safely, which is the essence of body mechanics.
