Foundations of Pathophysiology

Case Study: Scope of Pathophysiology

Mr. Reynolds, age 65, is slowly recovering from a recent heart attack. He has a history of emphysema but is having more difficulty breathing. He dislikes medications and any form of therapy.

Question 1

Using normal anatomy and physiology. Discuss how impaired ventilation can interfere with cardiac recovery and function.

Based on the patient’s medical history and his feelings about recovery programs. In conjunction with the patient’s need for medications and other therapies. Discuss the need for medication and participation in recovery programs and possible strategies. And the roles of other professionals in support of his recovery from the heart attack and to manage his respiratory condition.

Diagnostic Principles

Case Study: Diagnostic Principles – Gastric Ulcer

Ms. W. is a 55-year-old patient who consulted her physician because of recurrent epigastric pain. And nausea and two recent episodes of vomiting. In which the emesis was dark-colored. And granular in appearance. Her history includes heavy alcohol use, cigarette smoking. And persistent headaches. She has not followed all her physician’s previous recommendations. But has been controlling her headaches by taking two aspirins every few hours. Following tests. Ableeding gastric ulcer was diagnosed.

Question 1 , 2, 3, 4Discuss

the factors contributing to Ms. W.’s condition.

synergism, antagonism and potentiation as they apply to this case.

the potential effects of increased bleeding from the ulcer.

issues related to patient compliance.

Case Study: Inflammation and Healing – Fracture and Swelling

JL, a 50-year-old woman, fell. And broke the left tibia at the ankle. She is in the emergency department. Waiting for the fracture to be immobilized. The leg hurts and she notes that the ankle is swelling. A diagnosis of a simple fracture and sprain (damage to ligaments) is made.

Question 1 What is the cause of pain. And swelling? What can JL expect in the days to come as inflammation resolves and healing begins?

Question 2

What is the rationale for immobilizing the fractured bone?

Question 3

She is told to come back to the fracture clinic in 24 hours to have her cast checked. What could happen to the inflamed tissue if the edema increases in the casted area?
