Florida Nursing Assistant Competency Pracrice Exam

Which of the following could indicate a patient is at risk for dehydration?

1. A sudden increase in appetite

2. Dry mucus membranes

3. Frequent urination

4. Increased fluid intake

The correct answer is: Dry mucus membranes

Dry mucus membranes are a key indicator that a patient may be at risk for dehydration. Mucus membranes, such as those found in the mouth and nose, should be moist for optimal health. When a person is dehydrated, these membranes can become dry and sticky, signaling that the body is lacking sufficient fluids. This is particularly important in clinical settings, as it can help nursing assistants and healthcare providers to identify and address dehydration in patients promptly. In contrast, a sudden increase in appetite may be unrelated to hydration status and could indicate other issues. Frequent urination often suggests an adequate or excessive intake of fluids rather than dehydration. Similarly, increased fluid intake is contrary to the state of dehydration, as it typically helps to alleviate this condition. Understanding these signs assists in recognizing the potential risks to a patient's hydration status and enables timely and appropriate interventions.
