Fatigue refers to the pervasive feeling of tiredness. The tiredness can either be mental or physical forming the basis of its classification. Mental fatigue refers to the inability of an individual to maintain optimal cognitive functioning, whereas, physical fatigue is the inability to maintain optimal muscular functionality. Both kinds of fatigue can mild and fade with instances of rest or persistent transforming to chronic fatigue (Meirleir & McGregor, 2003) . This paper discusses the visual analogue scale for fatigue (VAS-F) one of the fatigue's measuring instrument and its usage in nursing, the manifestation of fatigue across different categories of individuals and two interventions that can be used in its alleviation.
The visual analogue scale for fatigue (VAS-F) is preferred for the assessment of fatigue. The tools consist of items that relate to the subjective feeling of fatigue and bear an analogue scale. The analogue scale consists of numbers that represent the level of the patients feels. The numbers range from zero to ten. Zero represents the least feeling of the subjective feeling while ten corresponds the extreme feeling. Some of the subjective feelings evaluated include tiredness, sleepiness, fatigue, energy level, feeling worn out, level of activity, vigor, desire to keep eyes open, desire to keep eyes closed, and desire to keep eyes open. The (VAS-F) is appropriate, and it preferred especially if the patient is able to discriminate the different levels of the subjective feeling (Ohsugi, Tanaka, Kodama & Murata, 2014) .

The subjective feelings target the different forms of fatigue manifest. Some of the common manifestations of fatigue include the feeling of being worn out. The patient in a worn-out state, looses their optimal functionality of the muscular and mental states, As such, there is a feeling wanting to close their eyes, avoid engaging in any activity, feeling less active, less energetic, less concentrated, and have an increased desire to lie down. Manifestation occurs in children and even adult patients (Meirleir & McGregor, 2003) .
Fatigue can be alleviated using two techniques. First, the patient needs administration of rest. It is particularly useful if the fatigue has no other underlying medical. The patient is prescribed to a certain amount of rest depending on the level of fatigue. On the other hand, fatigue can be treated using a combination of medication and rest. Some ailments such as cancer are known to manifest fatigue in their patients. Therefore, the patient should receive treatment based on the symptoms in addition to prescription of rest (Jelsness-Jørgensen, Bernklev & Lundin, 2018) .
In conclusion, this paper in addition to discussing the classification of fatigue, it also discusses (VAS –F) of one of the instruments for measuring fatigue and its usage in nursing, the manifestation of fatigue across different categories of individuals and two interventions that can be used to alleviate it. The (VAS-F) has an analogue scale that measures the subjective feeling of fatigue. It is preferred because the patient gives the level of the feeling. Fatigue manifest by the manifestation of the subjective feeling such as feeling worn out. As such it calls for administration of rest or a combination of rest and medication.
