For partners: how to help
Your partner is new to the UK and reading the Nhà guide in Vietnamese. Here is what each page says, and how you can help, in English. Send her the Vietnamese link; read the English here.
Đăng ký với bác sĩ gia đình (GP)
Registering with a GP is free in England, and she doesn't need ID, proof of address or proof of immigration status. Help her find a nearby surgery on the NHS website and do the online form together (about 15 minutes), or go in with her to fill in the paper form. In Wales the form is called GMS1. If she wants an interpreter at appointments, ask the surgery to record that she needs a Vietnamese interpreter; it's the surgery's job to arrange it, not yours.

Phiên dịch miễn phí khi đi khám bệnh
She has the right to a professional interpreter in NHS care, free of charge, and it's the surgery or hospital's job to arrange it. You can come with her, but you shouldn't be the interpreter, even if your Vietnamese is good: gaps and mistakes happen, and a professional lets you be there just to support her. Never use a child to interpret. Ask the surgery to record "Vietnamese interpreter needed" on her notes so it's booked every time.

Số khẩn cấp: 999, 111 và 101
Make sure she knows the three numbers and the difference: 999 (or 112) for danger, injury or a life at risk; 111 for an urgent health problem when she isn't sure what to do, or when the GP is closed; 101 for non-urgent police matters. On 111 she can ask for an interpreter. Practise the first sentence with her ("Ambulance, please", "Police, please") and make sure she can say your home address in English.
