Does you course have specific objectives for each lecture? The amount of reading is definitely doable, we sometimes have double that amount between lectures, or 7 days apart. I would read the material, with an eye on the objectives, and in particular study your class powerpoints or handouts very thoroughly. If you taped the lectures, it will be helpful to listen to them at least once more, and then again while you are re-reading your notes that you took during the original lecture.
You say you aced the first test? If that's the case, then do all the same things you did then for this test. You have time to do it, just study smart. If there are review questions in your textbook or study guide, do those, and also go online to the textbook's website, and take those review questions as well. If you have a HESI review book or NCLEX review book, you can do all the renal questions there too.
Your 110 questions are going to all be renal? I think that's great, it's tougher to study 5 big systems and try to figure out what 50 or 60 questions they can narrow it down to, IMO. That's what our tests are like.
Good luck, you've already proven you can do it!
