Q

HESI HINT: Changes in the heart and lungs result in less efficient utilization of O2, which reduces an individual’s capacity to maintain physical activity for long periods. What can be done to help increase this?

A

Physical training for older people can significantly reduce blood pressure and increase aerobic capacity. Exercise and nutrition.

Q

HESI HINT: Why are older people often unable to get sleep at night and do not sleep soundly after they fall asleep?

A
  • This is because they have shorter stages of sleep, particularly shorter cycles between stages 1 and 4 and REM sleep (stage 4 is deep sleep).
  • They are easily awakened by environmental stimuli.
  • They often compensate by napping during the day, which leads to further disruptions of night sleep.
  • A common response is the use of prescription sleeping pills, which can create still further problems of disorientation, etc.

34
Q

HESI HINT: What are the following changes that contribute to chronic constipation with age?

A
  • The number of enzymes in the small intestine is reduced, and simple sugars are absorbed more slowly, resulting in decreased efficiency of the digestive process.
  • The smooth-muscle content and the muscle tone of the wall of the colon decrease. Anatomic changes in the large intestine result in decreased intestinal motility.
  • Psychological factors, as well as abuse of over-the-counter laxatives, are factors.
  • Decreases in fluid intake and mobility contribute to constipation.
35
Q

HESI HINT: Tooth loss

A

Is not a normal aging process.

36
Q

HESI HINT: Why do older people appear to eat small quantities of food at mealtimes?

A

This is because the digestive system of older people features a decrease in the contraction time of the muscles, and more time is needed for the cardiac sphincter to open. Therefore it takes more time for the food to be transmitted to the stomach. Thus the sensation of fullness may occur before the entire meal is consumed.
