Nursing Theory

The purpose of this discussion is to compare and contrast two theories that were used as the basis for articles in the readings for this week. The first article applies Virginia Henderson’s grand theory of Activities of Living to organ donation after brain death (Nicely & DeLario, 2011). The second article tests a theory of health promotion for preterm infants based on Myra Levine’s Conservation Model of Nursing (Mefford & Alligood, 2011). This student will give a brief overview of each article and then she will compare and contrast the two.
Nicely & DeLario’s article relates each of the fourteen activities of Henderson’s theory to an intervention the nurse must perform for the brain-dead patient if the neurological injuries prevent the body from functioning properly (2011). For instance, Henderson’s first activity is normal breathing. In a brain-dead patient, there will be no spontaneous respirations. In applying Henderson’s theory, the nurse must be certain that intubation and ventilation is performed early to maintain organ viability. By executing all fourteen of Henderson’s activities for not only the patient but the patient’s family, the nurse will be “contributing significantly to transferring the gift of life from one human being to one of more patients the next phase of the donation process (Nicely & DeLario, 2011).

Levine’s model consists of four conservation principles that include conservation of energy, conservation of structural integrity, conservation of personal integrity and conservation of social integrity (as cited in Mefford & Alligood, 2011). According to Mefford & Alligood (2011), each of Levine’s principles can be applied to the health promotion of preterm infants. An example of this is reflected in the capacity of the family to adapt to the extreme stress of having a preterm infant. The family adaptation is related to Levine’s concept of social integrity (Mefford & Alligood, 2011).
Both theories have a similar framework in
