Test bank for introduction to radiologic and imaging sciences and patient care 8th edition by Adler

MULTIPLE CHOICE 1. One of your classmates consistently gets A’s on tests and homework, with no apparent effort or study. In talking with him, you discover he has a good strategy for studying that involves a. staying up late and pulling “all-nighters” before an examination. b. eating a heavy, “high-carb” meal the night before the examination. c. consistently allocating specific times of the day for studying and exercise. d. studying with friends using flashcards. ANS: C Waiting until the last minute to study increases anxiety to a point that it actually may interfere with the ability to learn and recall information. Studies have shown that short, regular periods of study and review result in greater recall than a long period of study followed by a long period of no exposure to the information. REF: p. 28 2. An example of a stress buffer is a. taking antacids the day of a big examination. b. intensive studying with close friends the night before a test. c. agreeing to work more hours a few days before a big test to ease your money problems. d. exercising with friends foN r 45R miI nuteG s thB e. dC ay bM efore a big test. ANS: D People who exercise regularly look forward to the relaxing benefits of the aerobic activity, which usually promotes improved sleep patterns, increased energy, and increased stress tolerance. REF: p. 25 3. The fight-or-flight response is a natural process of the body. It is characterized by a. the release of hormones to increase metabolism. b. decreased metabolism of fats and sugars to conserve available energy for later use by the body. c. a decreased heart rate with rapid respirations. d. increased circulation to the muscles of the digestive tract to hasten digestion in preparation for high energy expenditure. ANS: A The fight-or-flight response readies the body for action. Circulation increases in the long muscles, and the heart rate and respiration rate increase to supply more oxygen to the muscles. Sugars and fats are dumped into the system to supply the needed energy for physical activity. The physiologic responses include the release of hormones to increase metabolism, increases in fats and sugars for energy, and increases in heart rate and respiration. Blood flows at a greater-than-normal rate to the long muscles of the extremities, and the central nervous system is stimulated.
