And so, a happy ending.
It always makes me smile to see things work out.
One.
Tune in next time when we find out if this will be old dotty great aunt Bedelia’s only stop…
As always, I invite students and non-students to submit multiple choice questions appropriate for the upcoming exam on the Renal System (Physiology and Pathophysiology questions). Post questions with answers (three wrong and one right) in the comments section below.
Also, here’s an opportunity for two points of extra credit on the upcoming exam:
Submit your answer quick – only the first correct response (also posted in comments) earns points. I will try to post several more questions over the weekend – note, these extra credit vignettes may come from any of the chapters we studied this semester)
Presentation
A 62 year old man presented at the ER with sudden sensation of food being caught in his throat while swallowing. The patient is highly agitated and convinced he is choking although he appears to be getting air.
An emergency endoscopy reveals food stuck in the esophagus. With pressure, food bolus passed into the stomach successfully. A subsequent barium swallow and X Ray produced the image here.
What is the diagnosis?
As I’ve been doing lately, I wanted to offer the opportunity to my students (and anyone else who would like to) to submit questions for the Respiratory Unit Exam of my Pathophysiology class. Topics covered on this exam will focus primarily on the outline below. However, I wish to remind students that they are responsible for all the material covered in chapters 21-23 of Porth’s Essentials of Pathophysiology.
To submit questions, please provide a fully worked out multiple choice question in the comments section below. Also indicate the correct answer.
Respiratory Pathophysiology Outline (Please, forgive the formatting below, I’m having trouble fixing this appropriately in the browser):
*The distinction between Typical and Atypical pneumonia appears to be more historic than clinically valuable. For this reason, on our exam we will continue to call S. pneumoniae the most common form of ‘Typical’ pneumonia, but otherwise not use these terms.
Chapter 21 of Carol Porth’s Pathophysiology presents an introduction to respiratory anatomy and physiology. The following two chapters present pathologies that affect the system. I’ve outlined here the basics of lung A&P as notes from my reading of the chapter and I thought I would present that here as a guide for any of my students. I have yet to outline the second and third chapters, but there is a skeleton of conditions that we will cover. It is also worth noting that I expect my students to be able to recognize and identify the structural components of the respiratory system even though I did not include these elements in my outline …
Pulmonology Outline
Ventilation and Perfusion must be matched in order to optimally oxygenate blood in the lungs.
Questions
Pathologies
Like the James Brown of the Body
As I started grading the first Pathophysiology Exam on Cardiovascular Function in Health and Disease, the first material I saw was in answer to my questions about the flow of blood through the heart and to the rest of the body. I can’t say that I was happy with the results, but I want to emphasize that this is very basic material that we discussed and outlined in our class, but that I had also assumed was covered in Anatomy and Physiology last semester. After two passes through this material, it should be easily accessible in every student’s mind.
As a reminder of these functions and the flow of blood, here is Khan Academy’s summary of this material:
I believe that that is important foundational material, and you may have a pop quiz on it at any time.
stay on the scene
My Pathophysiology class is having its first exam coming up soon (February 19th) and it’s time to solicit questions for the exam. Really, this is for my students, however, if non-students want to contribute questions, I’ll entertain those too.
Qualifications to be accepted:
1. Be a well-phrased question with a clear answer (this is helped somewhat by #2)
2. Provide four or five answers (for multiple choice) to the question and indicate which one is correct.
3. Be on topic (i.e. regarding the basic anatomy and physiology of the cardiovascular system, peripheral vascular disease, defects of the heart (congenital), valvular disease, hypertension, or myocardial infarction – other topical questions will be considered, but may appear as extra credit if they were not covered in class)
4. Post here as a reply to this blog entry so that it is visible to others.
Getting Oxygen Where It’s Needed.
This is an older post of mine that I thought I should point back to because my general biology class is now covering cellular respiration.
