The fact that females even have to worry about safety issues when traveling alone makes me shake my head at the sad state of affairs our society is in. Every male should protect every female. Always. But enough of that... back on topic.
Remember that you don't have a spare tire. In fact, you aren't even provided with a can of fix-a-flat or a battery operated compressor with your new car.
Unfortunately, even road side assistance isn't necessarily trustworthy, reliable, or safe. Take a look around the forums here, as there are several very good threads with very valuable information on what you'll need to be able to safely change your tire (assuming you've researched and bought a compatible spare), as well as information on using a tire plug kit. Most all "fix-a-flat" type products won't work with the stock tires, as the layer of sound absorbing foam also absorbs the materials from fix-a-flat type products.
That being the case, a good tire plug kit is, IMO at least, a must-have. You'll also want a good compressor, too.
At a minimum, I'd take:
1. flush cutting cutters
2. Vice grips (I carry three different sizes)
3. Rubber cement (to lubricate the plug)
4. Quality tire plug kit
5. Air compressor
6. Air pressure gauge
7. Good quality gloves. Not just nitrile gloves, but gloves that are capable of protecting your hands. It's very easy to slip while removing a nail, screw, etc. from your tire and even easier still to bang up your hands on the wheel well when removing the offending item from your tire.
Your plug kit should include a tool for removing the valve stem, as well as a replacement valve stem itself.
There are a bunch of good YouTube videos on how to use a tire plug kit. Well worth taking a few minutes to watch a few of them.
Some people say that tire plugs are not a permanent repair. Most all of those guys own tire shops, and want to charge you to do a patch repair to make your plug repair "permanent." I've used dozens of tire plugs on vehicle tires since the early '80's, and I have never had one fail. They are as permanent and robust as a professional "tire repair" and will last the lifetime of your tire. That has been my experience, at least, and the experience of a lot of other non tire store owning drivers, too.
A tire plug kit will get you back on the road fast, and without the worry of having to change out a temporary spare or getting the tire "fixed" again.
The only issue with a plug kit is that it can be a bit difficult to use the reaming tool to enlarge the hole to the point that you can actually insert the plug. Believe it or not, rubber cement can help greatly with this. If you're having a hard time using the reaming tool, run a generous amount of rubber cement on the reaming tool, then immediately ream out the hole. Then coat the plug itself in rubber cement prior to inserting it into the tire. Using rubber cement, my wife was able to use a plug kit on her Sequoia out in the middle of the desert one night.
Have a safe journey.
