Question

stant / quiz: lesson 6 - the physical examination
safe body mechanics includes which of the following?
select one:
a. reaching over a barrier to lift an item
b: keeping legs close together for support
c. never sliding or rolling a heavy object
d. bending at the knees when lifting a heavy object

Explanation:

To determine the correct answer, we analyze each option based on safe body mechanics principles:

• Option a: Reaching over a barrier to lift an item is unsafe as it can strain the back and cause imbalance.
• Option b: Keeping legs close together reduces stability; a wider stance is better for support.
• Option c: Sliding or rolling heavy objects is often recommended to avoid lifting injuries, so "never" doing so is incorrect.
• Option d: Bending at the knees (while keeping the back straight) when lifting heavy objects is a core principle of safe body mechanics, as it uses leg muscles and reduces back strain.

Answer:

d. Bending at the knees when lifting a heavy object
