Arizona Certified Nursing Assistant (CNA) Practice Test

Before weighing a resident, it is crucial to ensure that the scale is balanced or calibrated. A properly calibrated scale guarantees the accuracy of the weight measurement. If the scale is not balanced, it could lead to incorrect weight readings, which could impact the care and treatment of the resident. Accurate weight measurements are important for assessing hydration status, nutritional needs, and determining medication dosages that may depend on the resident's weight.

While the resident's clothing, the time of day, and their recent meal can influence the weight measurement, they do not affect the fundamental operation and accuracy of the scale itself. Ensuring that the scale is appropriately set up is the primary step to obtaining a reliable weight. This foundational practice is essential for healthcare professionals to provide safe and effective care.
