Which client is considered unsteady?

A client who is shaking while standing is considered unsteady because the act of shaking typically indicates a lack of control over body movements and can suggest that the individual may have issues with balance or muscle coordination. This situation poses a risk of falling, which is a major concern in a healthcare setting, particularly for vulnerable populations such as the elderly or those with certain medical conditions.

In contrast, the other situations described do not indicate instability. A client reading in bed is typically secure and supported, while a client seated in a chair is also stable as they are not in a position that requires balance or weight-bearing. Similarly, a client lying down is in a safe position that does not involve any risk of falling or instability. Thus, the client who is shaking while standing stands out as the one demonstrating unsteadiness.
