The advice will be to shelter at home. Staying at home and sheltering may protect us from the initial blast if we are more than 5-6 miles from where the explosion occurs. With enough advance warning, we may be able to make one room better protected from radiation. In our own homes, we will have some access to food and fluids and whatever else we need for basic comfort. Also, we will be known to whatever local administration is established in a post-nuclear situation so that emergency aid, such as clean water, can be provided if available.
Suppose we survive the initial nuclear attack because we are well away from its epicentre, we still face the problem of a radioactive environment because of fall-out. This means we will have radioactive water supplies and radioactive food crops. Radiation poisoning could still kill us or leave us susceptible to various cancers, and either sterility or a raised risk of having damaged babies in the future. Some people would die from radiation poisoning.
Some of us lived through the Cuban missile crisis in the 1960s and the government 'public information' programme (called 'Protect and Survive') in the 1970s. In case you are interested, here is a link to one of the government information films from the 1970s.
