Which of the following are common signs of dehydration?

The signs of dehydration are crucial for a Certified Nursing Assistant (CNA) to recognize, as they indicate the body's need for fluids. Dark urine, dry mouth, fatigue, and weakness are all classic indicators of dehydration.

Dark urine is a direct sign that the body is conserving water and concentrating waste products, resulting in a deeper color. A dry mouth suggests a lack of moisture in the body, which is a common effect of decreased fluid intake. Fatigue and weakness often accompany dehydration because insufficient fluid levels can impair bodily functions and reduce energy levels, making individuals feel tired and weak.

These symptoms highlight the importance of monitoring fluid intake and ensuring patients stay hydrated, especially in settings where inhabitants may not recognize their need for fluids. Being able to identify these signs can prompt timely intervention, preventing complications associated with severe dehydration.

The other options, while they may be associated with different conditions, are not primary signs of dehydration. Redness of the skin can indicate various issues, including inflammation or allergic reactions. Rapid heartbeat might occur with multiple health challenges, such as stress or cardiovascular issues, and excessive sweating is not a sign of dehydration but rather an indication of heat regulation or exertion.
