The nurse is caring for clients at a long-term care facility. When considering activities in the summer heat, which physiologic change of renal aging can also result in geriatric dehydration?
A) Decreased ability to concentrate urine
B) Decreased renal blood flow
C) Thickening of the renal tubules
D) Double voiding
A
Feedback:
A gerontologic consideration of aging is the decreased ability to concentrate urine. This consideration leads to an increased susceptibility to dehydration further complicated by a deficit in thirst. Other age-related changes include a decrease in renal blood flow and a thickening of the renal tubules. These changes lead to an alteration in the excretion of drugs in older adults, increasing the risk of drug toxicity. Double voiding is remaining at the toilet after voiding to allow time for additional urine to be excreted.
