The nurse considers the patient's level of growth and development when using health beliefs and practices as a basis for planning care. A person's beliefs about health are shaped in part by the person's knowledge, lack of knowledge, or incorrect information about body functions and illnesses, educational background, traditions, and past experiences. These variables influence how a patient thinks about health. When you assess a patient's level of health, gather subjective data about the way the patient perceives physical functioning such as level of fatigue, shortness of breath, or pain. Then obtain objective data about actual functioning such as blood pressure, height measurements, and lung sound assessment. The manner in which a person handles stress throughout each phase of life influences the way he or she reacts to illness. A person who generally is very calm may have little emotional response during illness, whereas another individual may be unable to cope emotionally with the threat of illness and may overreact or deny the presence of symptoms and not take therapeutic action. Spirituality is reflected in how a person lives his or her life, including the values and beliefs exercised, the relationships established with family and friends, and the ability to find hope and meaning in life. Religious practices are one way that people exercise spirituality. Some religions restrict the use of certain forms of medical treatment.
