A 24-year-old male arrives at the emergency department via air transport after sustaining a fall while rock climbing. The patient is unresponsive with sluggishly reactive pupils upon arrival. His right arm and bilateral lower extremities have obvious fractures. He was intubated by EMS and requires mechanical ventilation. A CT scan reveals multiple head bleeds and intracranial swelling with a midline shift. The patient is rushed to surgery with the plan to relieve the pressure of the intracranial swelling.
-The generation time for Enterobacter aerogenes during the exponential growth phase is 30 minutes. If a single E.aerogenes cell begins dividing during this phase,how many cells would be present if counted after 5 hours?

The generation time is 30 minutes, so in 5 hours (300 minutes), there are 10 generations (300/30). The number of cells is 2^10, which equals 1024 cells.
