A nurse working in an urgent care clinic is collecting data from a client who takes montelukast.
Which of the following is an expected therapeutic effect of this medication?

Choice A rationale:

Fever is not a common side effect of acetaminophen. In fact, acetaminophen is often used to reduce fever.

Choice B rationale:

Jaundice, which is a yellowing of the skin or eyes, can be a sign of liver damage, a rare but serious side effect of acetaminophen.

Choice C rationale:

Diarrhea is not a common side effect of acetaminophen.

Choice D rationale:

Tinnitus, or ringing in the ears, is not a common side effect of acetaminophen.

Choice A rationale:

Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.

Choice B rationale:

Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.

Choice C rationale:

Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.

Choice D rationale:

Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.
