Leland Norman Holland, Jr., PhD (Norm), over 20 years ago, started out like many scientists, planning for a career in basic science research. Quickly he was drawn to the field of teaching in higher medical education, where he has spent most of his career since that time. Among the areas where he has been particularly effective are preparatory programs in nursing, medicine, dentistry, pharmacy, and allied health. Dr. Holland is both an affiliate and a supporter of nursing and allied health education nationwide. He brings to the profession a depth of knowledge in biology, chemistry, and medically related subjects such as microbiology, biological chemistry, and pharmacology. Dr. Holland's doctoral degree is in Medical Pharmacology. He is very much dedicated to the success of students and their preparation for work-life readiness. He continues to motivate students in the lifelong pursuit of learning. I would like to acknowledge the willful encouragement of Farrell and Norma Jean Stalcup. I dedicate this book to my beloved wife, Karen, and my three wonderful children, Alexandria Noelle, my double-deuce daughter; Caleb Jaymes, my number one son; and Joshua Nathaniel, my number three "O"! -LNH Michael Patrick Adams, PhD, RT(R), is an accomplished educator, author, and national speaker.
