Taking out third party insurance to get accredited to repair vehicles

Q: I have a workshop where I repair vehicles. In order for me to be accredited I have to take out a third party insurance in case any customer's vehicles get damaged at my workshop. If I do not take out this third-party insurance, I will not get accreditation.

Is it permissible for me to take out this third-party insurance?

Woman working as a nurse

Q: I am a Muslim woman who is training to be a nurse. I was wondering if it is halaal to work as a nurse. I will have to work and have contact with male patients. The work clothes are also not completely covering, so men can see my arms.

Is the money I get as a nurse halaal? Should I continue studying as a nurse or switch to another career?
