This care study, using the Roper, Logan and Tierney Model of Nursing, examines the presentation of a patient with a history of drug misuse and a current diagnosis of infective endocarditis and hepatitis C. While this particular model of nursing incorporates 12 activities of daily living, this care study will deal with three specific activities: maintaining a safe environment, communication and breathing. One of the main concerns arising from this care study was the inadequate management of pain for the patient. It is suggested in the literature that healthcare professionals do not always adequately address pain management, primarily because of fear of causing addiction. The authors suggest that the patient's history of drug misuse in this study may have further mitigated against him receiving adequate pain control.
