Question 1
A patient suffered multiple traumatic injuries and received many blood transfusions within a few days of the injuries. For which medical condition should the healthcare professional monitor the patient for?
◦ High blood pressure
◦ HIV infection
◦ Hemosiderosis
◦ Kidney damage
Question 2
What is the cause of free calcium in the cytosol that damages cell membranes by uncontrolled enzyme activation?
◦ Activation of endonuclease interferes with the binding of calcium to protein.
◦ Activation of phospholipases, to which calcium normally binds, degrades the proteins.
◦ An influx of phosphate ions competes with calcium for binding to proteins.
◦ Depletion of ATP normally pumps calcium from the cell.
