Wisconsin Nursing Home Administrators (NHA) Practice Exam

Hot water temperature at plumbing fixtures used by residents should not exceed 115-120 degrees F. This is to prevent scalding, as temperatures above 120 degrees F can cause serious burns in just a few seconds. Option A (105-110 degrees F) is too low and may not provide enough hot water for daily use. Option B (108-112 degrees F) is slightly above the recommended range and may still pose a risk of scalding. Option D (115-120 degrees F) is within the recommended range but is at the upper limit and may still be too hot for some individuals. Therefore, option C (110-115 degrees F) is the most appropriate temperature range to balance safety and comfort.
