Pt also began developing nausea and vomiting for 3 days x12 times last week. Pt also started developing diarrhea. Pt has states to have a notable generalized pruritic rash for 3 months that has been worsening. He reports he has been seen by dermatology and was told that the rash is due to certain allergies from food and has been using an unknown cream for 1 month that does not relieve his symptoms. Pt recently admitted for management of bleeding permacath and acute hypoxic respiratory failure likely 2/2 COPD requiring intubation and vent support.
