One Concern with Certain Antibiotics Is How Quickly They Are

question 18

Multiple Choice

One concern with certain antibiotics is how quickly they are excreted via active transport in tubular secretion. Would you expect an older individual to have this same problem with antibiotics?

• A)No. After a certain age, active transport of drugs and other substances completely stops.
• B)No. During the process of aging, tubular functions like secretion become less efficient, so antibiotics will stay in the system longer than usual.
• C)Yes. Aging doesn't really affect tubular secretion as much as it affects the other functions of the kidneys.
• D)Yes. Aging causes renal processing to become unusually fast, with many substances being excessively excreted.
