Dr. Singh asks the eye bank for more information about the donor. She finds out that the cornea donor was a previously healthy 30-year-old victim of a motorcycle crash who was on ventilator support for 4 days before his death. The donor’s corneas were harvested 3 days before the transplantations took place and were stored in a buffered medium containing 100 μg/mL gentamicin at 4°C.

How would you determine susceptibility of this P. aeruginosa to gentamicin?

In order to stay up all night to write the paper due tomorrow that she put off for the last month, Jillian takes Adderall, a powerful adrenergic agonist. What would be the impact on her stroke volume, heart rate and mean arterial pressure?

Describe 2 consequences in the body (think of organ or tissue damage) of high blood pressure.

A patient lost a lot of blood during surgery and his blood pressure dropped from 120/80 to 90/50. Given a drop in blood pressure, describe in detail and all steps of how the kidney renin-angiotensin-aldosterone system responds to this change in blood pressure. Include the four effect of angiotensin II. Name two medications that would block this pathway and where. (This is an incredibly important question for your exam! If handwritten, this question would fill most of the page.)
