Can anyone help me: I'm a student and i don't understand. my pt had a diagnosis "S/P ventriculoperitoneal shunt", I know what a ventriculoperitoneal shunt is and I know that s/p means status post, but can anyone tell me how being S/P VT is a diagnosis? Because I have a care plan due and I can't define my diagnosis and explain why my pt has it. Please...anyone...
