Which of the following is a method to assess skin integrity?

Checking skin hydration is a direct method to assess skin integrity because it provides insight into the overall health and condition of the skin. Hydrated skin typically appears plump and resilient, while dehydrated skin may show signs of dryness, flakiness, or cracking, which can indicate potential issues such as impaired skin barrier function. Monitoring skin hydration can help identify problems early, allowing for timely interventions that can prevent further skin deterioration.

The other options, while important for overall health assessment, do not directly evaluate skin integrity. Measuring blood pressure primarily assesses cardiovascular health, evaluating muscle strength focuses on musculoskeletal function, and assessing respiratory rate looks at respiratory health. All are critical components of a comprehensive health assessment but do not specifically address the condition of the skin itself.
