Final answer:
The OBRA nurse aide training regulations require a minimum of 100 hours of training.
Step-by-step explanation:
The subject of this question is Health and the grade level is High School.
The correct answer to the question is A) A minimum of 100 hours of training. The OBRA (Omnibus Budget Reconciliation Act) nurse aide training regulations require a minimum of 100 hours of training for nurse aides. This training typically includes both classroom instruction and clinical experience to provide students with the necessary knowledge and skills to work as nurse aides.
Option B is incorrect because clinical experience is an essential component of OBRA training. Option C is incorrect because written examinations are usually part of the nurse aide training process to assess students' understanding and competency. Option D is incorrect because nurse aide training is specific to nurse aides and does not include training for nurses.
