Nurses use scales to quantify subjective experiences and physiological parameters. For instance, the Numeric Pain Rating Scale allows patients to express their pain intensity on a scale from 0 to 10. Similarly, the Braden Scale is employed to predict pressure ulcer risk by assessing factors like sensory perception, moisture, activity, mobility, nutrition, and friction/shear. By utilizing these standardized tools, nurses can tailor care plans to meet the unique needs of each patient.
