Document Content and Description Below

A patient is found to have liver disease, resulting in the removal of a lobe of his liver. Adaptation to the reduced size of the liver leads to ___________ of the remaining liver cells. A. Metaplasia B. Organ atrophy C. Compensatory hyperplasia D. Physiologic hyperplasia--correct ans--C An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include: (Select all that apply.) A. Improved blood flow B. Slowed metabolic rate C. Decreased brain weight D. Improved nerve fiber conduction E. Less respiratory capacity--correct ans--B, C, E A 20-year-old college student has presented to her campus medical clinic for a scheduled Pap smear. The clinician who will interpret the smear will examine cell samples for evidence of: A. Changes in cell shape, size, and organization B. Presence of unexpected cell types C.
