Week 2: Altered Physiology

Week 2: Altered Physiology


Week 2: Altered Physiology

With a place squarely in the spotlight for patients diagnosed with all manner of disease, APRNs must demonstrate not only support and compassion, but expertise to guide patients’ understanding of diagnoses and treatment plans.
This expertise goes beyond an understanding of disease and sciences, such as cellular pathophysiology. APRNs must become experts in their patients, understanding their medical backgrounds, pertinent characteristics, and other variables that can be factors in their diagnoses and treatments.
This week, you examine alterations in the immune system and the resultant disease processes. You consider patient characteristics, including racial and ethnic variables, and the impact they have on altered physiology.

Learning Objectives
Students will:
• Evaluate cellular processes and alterations within cellular processes
• Analyze alterations in the immune system that result in disease processes
• Identify racial/ethnic variables that may impact physiological functioning
• Evaluate the impact of patient characteristics on disorders and altered physiology
