A 92-year-old client is scheduled for a colectomy. Which normal physiological change that ac-companies the aging process increases this client’s risk for surgery?

1. An increased tactile sensation
2. An increased metabolic rate
3. A relaxation of arterial walls
4. Reduced glomerular filtration rate

ANSWER

ANS: 4
An older adult is likely to have a reduced glomerular filtration rate. This limits the body’s ability to eliminate drugs or toxic substances. An older adult has reduced tactile sense, which decreases the client’s ability to respond to early warning signs of surgical complications, including sensing pressure over bony prominences. An older adult has a lower basal metabolic rate, reducing total oxygen consumption. The nurse should ensure the client obtains adequate nutritional intake when diet is resumed, but the client should avoid intake of excess calories.
