Abstract:

This interrupted case study is based on the real symptoms and laboratory results of a 65-year-old female stroke victim who is obese and on medication for hypertension but has no other significant health issues. The case begins with a description of the first symptoms she experiences while on the telephone with a friend. As the case develops, students are given additional information about the woman’s clinical history and the results of her diagnostic tests. Once a diagnosis is made, students use their knowledge of the cardiovascular system, along with additional information provided by the instructor, to decide if a particular treatment is appropriate. This case study incorporates elements of the anatomy and physiology of both the cardiovascular and nervous systems. Although the case was initially written for upper-level undergraduate human physiology students, it would also be suitable for any pre-health profession students or upper-level biology students with knowledge of these systems.

Objectives:
  • Identify common symptoms of ischemic stroke, beyond the well-known unilateral loss of muscle tone.
  • Explain the physiological causes of ischemic stroke.
  • Outline the connection between brain function and perfusion.
  • Describe the progression of stroke symptoms over hours and days.
  • Describe the process of hemostasis.
