One can never be too careful. We recently admitted a client with a SPMI diagnosis and are seeing him for medication delivery and administration. He also has diagnosis of Hepatitis C. He does not receive any injections or had any sharps issues. The nurse went for her visit. We usually sit and discuss their symptoms and medication side effects etc. Well, the nurse sat on a chair that had a chair tack sticking out of it and punctured her buttock. When she jumped up he commented that he had sat on that same chair earlier and bled. It isn't just needles. Be careful of where you sit!
