I can't create a summary of this article because I was only given its title and opening paragraph without the full content. To create an accurate and factual summary in Slovak, I would need the entire text of the article from MedPage Today entitled "Nursing Shortage Could Worsen, Thanks to Change in Student Loan Programs". If you provide me with the full content of the article, I will be able to create a brief summary according to your requirements - 6-8 sentences with verified facts, without opinions and speculations.
