You can use the English/Haitian Creole Medical Dictionary by Maude Heurtelou and Fequière Vilsaint. It is mainly a dictionary. I did browse it once or twice, I don’t remember seeing any sentences for patient communication in there.
Are you in pain? – Eske ou genyen doulè
Where is your pain? – Ki kote doulè ou ye?
Show me where’s your pain – Montre mwen kote doulè ou ye?
Take a deep breath and cough – Pran yon gran souf enpi touse
Roll over onto your right side – vire sou bò dwat ou.
Roll over onto your left side – Vire sou bò goch ou.
Roll over onto your back – Vire enpi kouche sou do ou.
Roll over onto your stomach – Vire enpi kouche sou vant ou.
