The numerical scale of nausea is a scale that starts with "0 (no nausea)" and ends with "10 (very severe nausea)" and is given a numerical value with 1 cm intervals. The numerical scale is one-dimensional and is mainly used to evaluate the severity of pain.

There are four options in the two-question scale, each with 0, 1, 2, or 3 points. The first question asks whether there is vomiting or retching, if any, and the frequency; the answers are "0" no, "1" once, "2" twice, "3" three times or more, with four options. The second question asks whether there is nausea (feeling of discomfort in the stomach and feeling like vomiting), if any, whether the feeling of nausea affects your ability to get out of bed, move around comfortably in bed, walk normally, or your daily life activities such as eating and drinking; the answers are "0" not very often, "1" sometimes, "2" often or often, and "3" always, with four options. The numerical values of the answers given to the first and second questions are added up and the result is found.
