Question 1

The aging kidney can be described as having:&#10;A) a deceased number of nephrons.&#10;B) an overall increase in the amount of kidney tissue.&#10;C) increased diluting capacity.&#10;D) increased renal blood flow.

Accepted Answer

The aging kidney typically experiences a decrease in the number of nephrons, which are the functional units responsible for filtering blood and producing urine. This reduction in nephron number contributes to a decline in kidney function with age.

Question 2

Conditions linked to age-related bone loss include all of the following EXCEPT:&#10;A) malabsorption&#10;B) alcohol abuse&#10;C) hypoparathyroidism&#10;D) inactivity

Accepted Answer

Hypoparathyroidism is not linked to age-related bone loss. Instead, it typically leads to increased bone density due to decreased bone resorption, which is opposite to the process of bone loss. Conditions like malabsorption, alcohol abuse, and inactivity are associated with increased risk of bone loss as they can lead to decreased bone density and strength.

Question 3

Which of the following is a biological marker of sarcopenia?&#10;A) AST&#10;B) Serum albumin&#10;C) Vitamin E&#10;D) CK

Accepted Answer

Serum albumin is a biological marker of sarcopenia, reflecting nutritional status and inflammation, both of which are related to muscle mass and function.

Question 4

Somatopause is associated with a decreased secretion of:&#10;A) Growth hormone&#10;B) Thyroid hormone&#10;C) Epinephrine&#10;D) Aldosterone

Accepted Answer

Somatopause is associated with a decreased secretion of growth hormone, which typically occurs with aging.

Question 5

The following analytes decrease with age EXCEPT:&#10;A) Total protein&#10;B) Creatinine clearance&#10;C) Total cholesterol&#10;D) Albumin

Accepted Answer

Total cholesterol levels tend to increase with age, while total protein, creatinine clearance, and albumin levels generally decrease as a person gets older.

Question 6

All of the following are physiological variables affecting geriatric patients EXCEPT:&#10;A) Age&#10;B) Sex&#10;C) Medications&#10;D) Physical activity

Accepted Answer

Medications are not physiological variables; they are external factors that can influence physiological variables.
