Part 1
Quality of life (QOL) is a multidimensional concept that is influenced by culture,
judgments, individuals’ perceptions, beliefs, purposes, expectations, experiences, as well as
perceptions. The quality of life concept perceptions can demonstrate changes over time and it
entails mental, physical, as well as social relations in the family and outside the family,
environmental actions too. Health is seen by the public health community as a multidimensional
construct, which comprises mental, physical, and social domains. Consequently, as medical and
public health developments have resulted in cures along with better treatments of current
diseases along with delayed mortality, it was reasonable that those who measure health outcomes
would start to assess the population’s health not only based on saving lives, but on improving the
quality of lives. This assessment has become fundamental in the use of QOL in measuring the
level of satisfaction among the patients by the nurses that make it an important concept in the
healthcare settings. Though health is one of the vital domains of overall QOL, there exist other
domains that include housing, jobs, schools, and the neighbourhood. The elements of culture,
values, as well as spirituality, are also crucial domains of QOL, which add to the complexity of
its measurement. However, researchers have established important methods, which have helped
to conceptualize along with measuring the multiple domains. This has influenced the manner that
nurses and other professionals in health care have measures the QOL among their clients
(McCaffrey, Bradley, Ratclife & Currow, 2016).

In the contemporary nursing practice, the QOL has increasingly become important in
promoting the acquisition of knowledge among nurses in promoting the health outcomes in the
healthcare setting. The QOL is a concept worth exploring because it has no definite definition
because it changes over time. Many studies have not developed a concrete definition of this
concept for many decades making it an ambiguous concept, especially in the application of the
contemporary nursing theories (Shahidi, Bernier & Cohen, 2010). Nonetheless, QOL is
important in the nursing practice because it will help patients with different conditions because
the perceptions of the patients can change with disease stage and kind of necessary interventions.
Furthermore, the QOL instruments that measure the level of patient satisfaction has been
developed. The capability of the QOL tool to identify clinically vital changes in the patient is
crucial, especially when contrasting the relative costs along with gains of alternative
interventions in the healthcare environment. This is designed to improve the patient outcomes,
particularly improving the quality of life among the patients. This is important in making sure
that the patient makes informed decisions regarding life based on the outcomes of the QOL
instruments. This makes QOL an important nursing instrument in the healthcare setting towards
improving the patient outcomes and also helps to inform the contemporary nursing theories.

The Mishel's Uncertainty in illness theory is one the middle range theories that explain
the way patients cognitively progression illness-related spurs plus the way they structure
meaning for the occurrences surrounding the illness or disease. The theory has its strongest
support amongst people that are experiencing an acute stage of disease or are in downward
